If this is the<br>case, reconsider the detection method.| Unlike conventional Photoelectric Sensors, the variation in the sensitivity of E3S-A Photoelectric Sensors is minimal. This means the sensitivity can be adjusted on only a single Photoelectric Sensor, and then the adjusters on the other Photoelectric Sensors can be set to the same scale position. There is no need to adjust the sensitivity of each Photoelectric Sensor individually. **9** (c)Copyright OMRON Corporation 2007 All Rights Reserved. http://www.ia.omron.com/ **E3S-A** ## **Safety Precautions** ## **WARNING** **This product is not designed or rated for ensuring safety of persons. Do not use it for such purposes.** ## **Precautions for Correct Use** Do not use the product in atmospheres or environments that exceed product ratings. ## **Mounting** ## **Position of Optical Axis of Through-beam Model** Unlike conventional through-beam sensors, the E3S-A Through-beam Photoelectric Sensor incorporates 2 lenses. The lens actually in use is the one marked with an arrow indicating the position of the optical axis. When using a Slit, attach it to the lens marked with the arrow. **==> picture [149 x 72] intentionally omitted <==** **----- Start of picture text -----**<br> Unused lens<br>Optical axis indicator arrow<br>**----- End of picture text -----**<br> Arrow indicating optical axis position Lens actually in use (attach the Slit to this lens) ## **Position of Arrow Indicating Optical Axis** |**Model**|**Position of lens in use**| |---|---| |E3S-A<br>(Vertical Sensors)|Top| |E3S-A<br>(Horizontal<br>Sensors)|Bottom| ## **Mounting Bracket (Provided)** The direction of the optical axis coincides with the machine axis of the E3S-A when the mounting screw is inserted into the lock hole of the Mounting Bracket. If the mounting surface and the screw hole are correctly aligned toward the sensing object (or toward the Retroreflector for a Through-beam Sensor), the mechanical axis and optical axis will be aligned when the screw is inserted into the hole. Incident light will be detected, and time-consuming adjustment will not be necessary. (If, however, the mounting surface is not flat, adjustment of the optical axis may still be required.) Adjust the position of the Sensor so that incident light points at the center. Make sure that the incident light is at a fixed position. The maximum tightening torque of the screw is 0.53 N.m max. **==> picture [169 x 53] intentionally omitted <==** **----- Start of picture text -----**<br> Base of mounting<br>bracket<br>Optical axis<br>Bracket can move<br>Machine axis in this direction<br>Optical axis lock hole (M3)<br>**----- End of picture text -----**<br> ## ● **Adjustments** ## **E39-S46 Through-beam Slits** (Accessory, order separately) Use the rubber attachment with the metal cover if a slit width of 2 mm is required. (A Slit is not required in this case.) Insert the 0.5- or 1-mm Slit between the metal cover and rubber attachment if a slit width of 0.5 or 1 mm is desired. These Slits fit into the rubber attachment. ## **Tightening the Connector** Manually tighten the connector until the threads have completely disappeared. If tightening is insufficient, the degree of protection may not be maintained, or the connector may become loose when it is subjected to vibration. Using pliers to tighten the connector may damage it. **==> picture [16 x 5] intentionally omitted <==** **----- Start of picture text -----**<br> Screw<br>**----- End of picture text -----**<br> **==> picture [128 x 34] intentionally omitted <==** Use the E39-L60 Close Mounting Plate (provided) if the Sensor is mounted using mounting brackets or if it is mounted directly.

Order one for every two sets of Photoelectric Sensors. - For mounting, refer to the figure of the Through-beam Slits. **==> picture [235 x 128] intentionally omitted <==** **----- Start of picture text -----**<br> Emitter<br>Receiver<br>Up to two units<br>Y = 0 can be attached.<br>Note: The arrows on the Filters can be attached in<br>either direction when two Sensors are<br>mounted next to each other. The Filter<br>attached to an Emitter and to the<br>corresponding Receiver must be the same<br>in direction of polarization or the Sensor will<br>not function.<br>**----- End of picture text -----**<br> - The arrow printed on the cover indicates the direction of polarization. By attaching the Filters opposite to each other in polarization to the Emitters and the Receivers in rows, mutual interference can be prevented (in any case, the Filter attached to an Emitter and to the corresponding Receiver must be the same in direction of polarization or the Photoelectric Sensor will not function). ## **Operating Mode Selection** ## Turbo **Function (** Turbo **Switch)** The turbo function is effective with the turbo switch pressed, and the function is reset automatically when released. With the turbo function switched ON, the light spot is visible even at a distance of 200 mm, making it easy to check the sensing position and the angle of the optical axis. ## **Precautions** - (1)Do not keep the turbo switch pressed for longer than 3 minutes. (It will not break even if it is pressed for an extended period.) - (2)Pressing the switch may change the timer delay settings. Set the timer after using the turbo function to check the optical axis. - (3)To press the switch, use a force of 9.8 N max. **==> picture [137 x 126] intentionally omitted <==** **----- Start of picture text -----**<br> The intensity of the<br>red spot will be<br>increased, making<br>visual confirmation<br>much easier.<br>PUSH<br>Sensitivity adjuster<br>The OFF-delay timer adjuster is<br>used as a turbo switch (black).<br>**----- End of picture text -----**<br> As shown in the following illustration, the E3S-A has an operating mode selector on the panel where the Receiver connector is located.

When this switch is ON, the intensity of the red LED light source can be increased to make a brighter spot. ## **Using the E39-R5 Optical Axis Reflector for Throughbeam Sensors** (Accessory, order Separately) Use this attachment when the set distance is long and adjustment is mechanically difficult with a sensing object. **==> picture [189 x 93] intentionally omitted <==** **----- Start of picture text -----**<br> E3S-AT@@<br>Eye Receiver<br>E39-R5<br>Optical Axis Confirmation Reflector<br>E3S-AT@@<br>Emitter<br>**----- End of picture text -----**<br> - Attach the Reflector to the Receiver. - Look at the Reflector from right behind the Emitter. The Reflector should be bright with red light when the optical beam strikes the Reflector. If the Emitter has a turbo function, the Reflector looks brighter with the function switched ON. - When the Reflector is removed, the light beam strikes the Receiver. **11** (c)Copyright OMRON Corporation 2007 All Rights Reserved. http://www.ia.omron.com/ **E3S-A** (Unit: mm) ## **Dimensions** ## **E3S-A Built-in Amplifier Photoelectric Sensor** **Through-beam Sensors (Horizontal) Pre-wired Sensors** **==> picture [512 x 601] intentionally omitted <==** **----- Start of picture text -----**<br> E3S-AT11/21/31/41 (Receiver) Sensitivity adjuster (white) 4-dia. vinyl-insulated round cable with<br>4 conductors<br>Timer adjuster (black) *1<br>(Conductor cross<br>With Mounting Bracket Attached Light indicator (red) 40 (4) Insulator diameter: section: 0.2 mm [2] ,<br>12.9 7 5.5 1.1 mm),<br>Optical Standard length: 2 m *2<br>axis<br>12.4 12 8.8 dia.<br>28.9 16.9<br>3.1 7.2 Stability indicator (green)<br>Emitter: E3S-AT@@-L *1.

(2) Do not use the Sensor in environments where the cables may become immersed in oil or other liquids or where liquids may penetrate the Sensor. Doing so may result in damage from burning and fire, particularly if the liquid is flammable. **C-1** (c)Copyright OMRON Corporation 2007 All Rights Reserved. http://www.ia.omron.com/ **Photoelectric Sensors Technical Guide** ## **Precautions for Correct Use** ## ● **Design** ## **Power Reset Time** The Sensor will be ready to detect within approximately 100 ms after the power is turned ON. If the Sensor and the load are connected to separate power supplies, turn ON the Sensor power before turning ON the load power. Any exceptions to this rule are indicated in _Safety Precautions_ in individual product information. ## **Turning OFF Power** An output pulse may be generated when the power is turned OFF. It is recommended that the load or load line power be turned OFF before the Sensor power is turned OFF. ## **Power Supply Types** An unsmoothed full-wave or half-wave rectifying power supply cannot be used. ## **Mutual Interference** Mutual interference is a state where an output is unstable because the Sensors are affected by light from the adjacent Sensors. The following measures can be taken to avoid mutual interference. |**Counter-**<br>**measure**|**Concept**|**Through-beam Sensors**|**Reflective Sensors**|**Reflective Sensors**| |---|---|---|---|---| |1|Use a Sensor<br>with the<br>interference<br>prevention<br>function.|If Sensors are mounted in close proximity, use Sensors with the interference prevention function.<br>10 or fewer Sensors: E3X-DA@-S, E3X-MDA, E3C-LDA Fiber Sensors<br>Performance, however, will depend on conditions.

Exceptions are indicated in _**Safety Precautions**_ in individual product information. ## **Separation from High Voltage (Wiring Method)** Do not lay the cables for the Sensor together with high-voltage lines or power lines. Placing them in the same conduit or duct may cause damage or malfunction due to induction interference. As a general rule, wire the Sensor in a separate system, use an independent metal conduit, or use shielded cable. ## **Cable Tensile Strength** When wiring the cable, do not subject the cable to a tension greater than that indicated in the following table. |**Cable diameter**|**Tensile strength**| |---|---| |Less than 4 mm|30 N max.| |4 mm orgreater|50 N max.| Note: Do not subject a shielded cable or coaxial cable to tension. ## **Repeated Bending** **==> picture [33 x 6] intentionally omitted <==** **----- Start of picture text -----**<br> Power line<br>**----- End of picture text -----**<br> ## **Work Required for Unconnected Leads** Unused leads for self-diagnosis outputs or other special functions should be cut and wrapped with insulating tape to prevent contact with other terminals. Normally, the Sensor cable should not be bent repeatedly. (For bending-resistant cable, see _**Attachment to Moving Parts**_ on page **C-4** .) **C-3** (c)Copyright OMRON Corporation 2007 All Rights Reserved. http://www.ia.omron.com/ **Photoelectric Sensors Technical Guide** ## **Power Supply** When using a commercially available switching regulator, ground the FG (frame ground) and G (ground) terminals.

Use the following methods to attach and remove Fiber Units. ## **(1) Attaching Fibers** Open the protective cover, insert the fiber up to the insertion mark on the side of the Fiber Unit, and then lower the lock lever. **==> picture [232 x 99] intentionally omitted <==** **----- Start of picture text -----**<br> Lock released position<br>Protective cover<br>Lock lever Locked<br>position Insertion<br>position<br>SSA<br>\ Fiber insertion mark <a<br>Fiber<br>9mm<br>**----- End of picture text -----**<br> ## **(2) Removing Fibers** Open the protective cover, lift up the lock lever, and pull out the fibers. **==> picture [164 x 24] intentionally omitted <==** **----- Start of picture text -----**<br> Lock released Protective cover<br>position<br>Locked position<br>**----- End of picture text -----**<br> ## **Optical Axis Adjustment** Move the Photoelectric Sensor both vertically and horizontally and set it in the center of the range in which the operation indicator is lit or not lit. For the E3S-C, the optical axis and the mechanical axis are the same, so the optical axis can be easily adjusted by aligning the mechanical axis. **==> picture [231 x 189] intentionally omitted <==** **----- Start of picture text -----**<br> Receiver<br>Incident indicator or Operation indicator<br>ON OFF<br>Emitter<br>l Optimum value<br>1<br>2 Incident indicator or Operation indicator<br>ON > OFF<br>The axis from the center of the lens to the center of<br>the beam for the Emitter and the axis from the<br>center of the lens to the center of the reception area<br>for the Receiver.<br>Mechanical axis: The axis perpendicular to the center of the lens.<br>Emitter Optical axis Optical axis Receiver<br>Mechanical axis<br>Emission beam Reception area<br>**----- End of picture text -----**<br> Optical axis: The axis from the center of the lens to the center of the beam for the Emitter and the axis from the center of the lens to the center of the reception area for the Receiver. Mechanical axis: The axis perpendicular to the center of the lens. Note:1.To maintain the fiber characteristics, make sure that the lock is released before removing the fibers. 2. Lock and unlock the fibers at an ambient temperature of −10 to 40°C. **C-5** (c)Copyright OMRON Corporation 2007 All Rights Reserved. http://www.ia.omron.com/ **Photoelectric Sensors Technical Guide** ## ● **Operating Environment** ## **Water Resistance** Do not use in water, in rain, or outside. ## **Ambient Conditions** Do not use this Sensor in the following locations. Otherwise, it may malfunction or fail. - (1) Locations exposed to excessive dust and dirt - (2) Locations exposed to direct sunlight - (3) Locations with corrosive gas vapors - (4) Locations where organic solvents may splash onto the Sensor - (5) Locations subject to vibration or shock - (6) Locations where there is a possibility of direct contact with water, oil, or chemicals - (7) Locations with high humidity and where condensation may result ## **Environmentally Resistive Sensors** The E32-T11F/T12F/T14F/T81F-S/D12F/D82F and E3HQ can be used in locations (3) and (6) above. ## **Optical Fiber Photoelectric Sensors in Explosive Gas Atmospheres** The Fiber Unit can be installed in the hazardous area, and the Amplifier Unit can be installed in a non-hazardous area. ## **<Reason>** For explosion or fire due to electrical equipment to occur, both the hazardous atmosphere and a source of ignition must be in the same location. Optical energy does not act as an ignition source, thus there is no danger of explosion or fire. The lens, case, and fiber covering are made of plastic, so this setup cannot be used if there is a possibility of contact with solvents that will corrode or degrade (e.g., cloud) the plastic. ## **<Ignition Source>** Electrical sparks or high-temperature parts that have sufficient energy to cause explosion in a hazardous atmosphere are called ignition sources. **==> picture [193 x 93] intentionally omitted <==** **----- Start of picture text -----**<br> Hazardous area Non-hazardous area<br>Fiber Unit<br>Amplifier Unit<br>Sensing object<br>**----- End of picture text -----**<br> ## **Influence from External Electrical Fields** Do not bring a transceiver near the Photoelectric Sensor or its wiring, because this may cause incorrect operation. ## ● **Maintenance and Inspection** ## **Points to Check When the Sensor Does Not Operate** - If the Sensor does not operate, check the following points. - (1) Are the wiring and connections correct? - (2) Are any of the mounting screws loose? - (3) Are the optical axis and sensitivity adjusted correctly? - (4) Do the sensing object and the workpiece speed satisfy the ratings and specifications? - (5) Are any foreign objects, such as debris or dust, adhering to the Emitter lens or Receiver lens? - (6) Is strong light, such as sunlight (e.g., reflected from a wall), shining on the Receiver? - (7) Do not attempt to disassemble or repair the Sensor under any circumstances. - (8) If you determine that the Sensor clearly has a failure, immediately turn OFF the power supply. ## **Lens and Case** The lens and case of the Photoelectric Sensor are primarily made of plastic. Dirt should be gently wiped off with a dry cloth. Do not use thinner or other organic solvents. - The case of the E3ZM, E3ZM-C and E3S-C is metal. The lens, - however, is plastic. ## ● **Accessories** ## **Using a Reflector (E39-R3/R37/RS1/RS2/RS3)** ## **During Application** - (1) When using adhesive tape on the rear face, apply it after washing away oil and dust with detergent. The Reflector cannot be mounted if there is any oil or dirt remaining. - (2) Do not press on the E39-RS1/RS2/RS3 with metal or a fingernail.This may weaken performance. - (3) This Sensor cannot be used in locations where oil or chemicals may splash on the Sensor. ## **M8 and M12 Connectors** - Be sure to connect or disconnect the connector after turning OFF the Sensor. - Hold the connector cover to connect or disconnect the connector. - Secure the connector cover by hand. Do not use pliers, otherwise the connector may be damaged. - If the connector is not connected securely, the connector may be disconnected by vibration or the proper degree of protection of the Sensor may not be maintained. ## ● **Others** ## **Values Given in Typical Examples** The data and values given as typical examples are not ratings and performance and do not indicate specified performance. They are rather values from samples taken from production lots, and are provided for reference as guidelines. Typical examples include the minimum sensing object, engineering data, step (height) detection data, and selection list for specifications. ## **Cleaning** - Keep organic solvents away from the Sensor. Organic solvents will dissolve the surface. - Use a soft, dry cloth to clean the Sensor. **C-6** (c)Copyright OMRON Corporation 2007 All Rights Reserved. http://www.ia.omron.com/ ## **Read and Understand This Catalog** Please read and understand this catalog before purchasing the products.
