**SA1E** 

**SA1E Miniature Photoelectric Switches** 

## **Key features:** 

- Seven sensing methods: through-beam, polarized retroreflective, small beam reflective, diffuse, background suppression, convergent, and transparent. 

- 2m cable type and M8 connector. 

- NPN output, PNP output, light ON, dark ON can be selected. 

- Coaxial polarized retro-reflective type (SA1E-X) available for sensing transparent objects. 

- Background suppression (SA1E-B) type detects objects only, ignoring the background. 

- Red LED available for easy alignment in long distance applications (SA1E-T, -P, -N, and -B) 

- Convergent reflective type (SA1E-G) is ideal for detecting objects at a short distance with a background. 

- Also available without sensitivity adjustment (SA1E-T, -P) 

- Air blower mounting block for installing an air blower to clean the lens sur face. Ideal to maintain a clean lens surface and sensor performance. 

- UL Listed and CE marked 

- IP67

1. Maintain at least the distance shown below between the SA1E photoelectric switch and reflector. 

- IAC-R5/R6/R7  /R8: 100 mm 

- IAC-RS1/RS2: 150 mm The detection distance cannot be guaranteed if the reflector is deformed or the tape type reflector is applied on uneven surface. 

2. Cable length: 1m (50g when the cable length is 2m, 55g for laser models. 110g when the cable length is 5m, 120g for laser models.) 

3. Cable length: 1m (55g when the cable length is 2m. 120g when the cable length is 5m.) 

4. For laser models insert L in place of  . 

## **Slit and Sensing Range** 

A slit, which changes the beam size of through-beam sensors, can easily be attached to the sensing side of the through-beam projector and receiver. Three different slit widths are available.

## **Safety Precautions** 

Turn off power to the SA1E Miniature Photoelectric Switches before installation, removal, wiring, maintenance, and inspection. Failure to turn power off may cause electrical shock or fire hazard. 

## **Instructions** 

## **1. Indicator and Output Operation** 

(except for background suppression type) 

**==> picture [53 x 7] intentionally omitted <==**

**----- Start of picture text -----**<br>
Stable LED (green)<br>**----- End of picture text -----**<br>


Sensitivity Control Operation LED (yellow) 

|Operation<br>Level|1.2 and<br>over<br>1.0<br>0.8 and<br>below|Stable Incident<br>Unstable Incident<br>Unstable<br>Interruption<br>Stable<br>Interruption|ON<br>OFF<br>ON|ON<br>OFF|OFF<br>ON|PLCs|
|---|---|---|---|---|---|---|



- The operation LED turns on (yellow) when the control output is on. 

- The stable LED turns on (green) either at stable incident or stable interruption. Make sure to use the photoelectric switch after the stable operation is ensured. 

- In the light ON operation, the output turns on when the receiving light intensity level is 1.0 or over as shown on the right. 

- In the dark-ON operation, the output turns on when the receiving light intensity level is 1.0 or less as shown on the right. 

## **2. Optical Axis Alignment (Light ON)** 

## Through-beam 

Fasten the receiver temporarily. Place the projector to face the receiver. Move the projector up, down, right and left to find the range where the operation LED turns on. Fasten the projector in the middle of the range. Next, move the receiver up, down, right and left in the same manner and fasten in the middle of the range where the operation LED turns on. Make sure that stable LED turns on at stable incident and stable interruption. 

## Polarized retroreflective 

Install the reflector perpendicularly to the optical axis. Move the SA1E photoelectric switch up, down, right and left to find the range where the operation LED turns on. Fasten the switch in the middle of the range. Polarized retroreflective type can be installed also by finding the position where the reflection of projected red light is most intense, while observing the reflection on the reflector from behind the switch. Make sure that stable LED turns on at stable incident and stable interruption. 

Diffuse-reflective/Small-beam reflective/Convergent reflective 

Place the SA1E photoelectric switch where the switch can detect the object. Move the switch up, down, right and left to find the range where the operation LED tuns on. Fasten the switch in the middle of the range. Make sure that stable LED turns on at stable incident and stable interruption. Because the light source element of small-beam reflective type is a red LED, visual inspection is possible as well.

**SA1E** 

## **3. Sensitivity Adjustment** 

- Referring to the table to the right, adjust the sensitivity of the SA1E photoelectric switch when necessary, in such cases as the through-beam type is used to detect small or translucent objects or the reflective type is affected by background. The table explains the status of operation LED when the operation mode is set to light ON. 

   - After adjusting the sensitivity, make sure that stable LED turns on at stable incident and stable interruption. For detecting objects too small to turn on the stable LED, use an optional slit. 

- Sensitivity is set to the maximum at the factory before shipment. When adjusting the sensitivity, use the screwdriver supplied with the SA1E photoelectric switch to turn the control as shown below, to a torque of 0.05 N·m maximum.

1. When the background is far off and not detected, turn the control 360°, and set the point as point C. 

2. Because the control is multi-turn, it may take more than one turn to move from point A to point B.

3. Turning the control clockwise lengthens the sensing dis tance. 

4. Background suppression (BGS) type is not provided with a stable LED. 

## **5. Power Supply and Wiring** 

- Do not use the SA1E photoelectric switch at the transient status immediately after turning on the power (approx. 100 ms, back ground suppression type: 200 ms). When the load and switch use different power supplies, make sure to power up the switch first. 

- • Use a power supply with little noise and inrush current, and use the photo- 

   - Use a power supply with little noise and inrush current, and use the photoelectric switch within the rated voltage range. Make sure that ripple factor is within the allowable limit. Do not apply AC volt age, otherwise the switch may blow out or burn. 

   - When using a switching power supply, make sure to ground the FG (frame ground) terminal, otherwise high-frequency noise may affect the photoelectric switch. 

- Turn power off before inserting/removing the connector on photo electric switch. Make sure that excessive mechanical force is not applied to the connector. Connect the connector cable to a tight ening torque of 0.5 N·m maximum. 

- To ensure the degree of protection, use the applicable connector cable for the connector type. Connector cables are ordered sepa rately. 

- Avoid parallel wiring with high-voltage or power lines in the same conduit, otherwise noise may cause malfunction and damage. When wiring is long, use a separate conduit for wiring. 

- Use a cable of 0.3 mm[2] minimum core wires, then the cable can be extended up to 100m.

## **6. Installation Installing the Photoelectric Switch** 

- Do not install the SA1E photoelectric switches in an area where the switches are subject to the following conditions, otherwise mal function and damage may be caused. 

- Inductive devices or heat source Extreme vibration or shock Large amount of dust Toxic gases Water, oil, chemicals Outdoor 

- Make sure to prevent sunlight, fluorescent light, and especially the fluorescent light of inverters from entering the receiver of the pho toelectric switch directly. Keep the through-beam type receiver away from intense extraneous light. 

- Interference prevention allows two SA1E switches to be mounted in close proximity. However, the through-beam type is not equipped with interference prevention. Maintain appropriate dis tance between the switches referring to the lateral displacement characteristics on pages 218, 219, and 220. 

- Because the SA1E photoelectric switches are IP67 waterproof, the SA1E can be exposed to water. However, wipe water drops and smears from the lens and slit using a soft cloth to make sure of the best detecting performance. 

- Polycarbonate or acrylic resins are used for optical elements. Do not use ammonia or caustic soda for cleaning, otherwise optical elements will be dissolved. To remove dust and moisture build-up, use soft dry cloth. 

- Tighten the mounting screws (M3) to a torque of 0.5 N·m. Do not tighten the mounting screws excessively or hit the switch with a hammer, otherwise the protection degree cannot be maintained. 

## **Installing the air blower mounting block SA9Z-A02** 

- When installing the SA9Z-A02 on the SA1E photoelectric switch, use the attached M3 × 20 mounting screws and tighten to a torque of 0.5 N·m maximum. 

- Do not use the mounting screw (M3 × 12) supplied with the mount ing bracket (SA9Z-K01) to mount the SA1E photoelectric switches. 

- The SA9Z-A02 cannot be used with the through-beam slits (SA9Z-S06 to S14). 

- The air tube fitting (M5) can be installed to either the top or side. The air tube is not supplied. 

- Close the unused port using the supplied air supply port plugging screw and gasket to a tightening torque of 1 to 2 N·m maximum. The recommended air pressure is 0.1 to 0.3 MPa. 

## **Installing the background suppression (BGS) type** 

- This sensor can detect objects correctly when the sensor head is installed perpendicular to the moving object. Install the sensor head as shown below to minimize sensing errors.

## **Installing the Reflector** 

- Use M4 mounting screws for the IAC-R5 reflector and M5 mount ing screws for the IAC-R6 reflector. Tighten the mounting screws to a tightening torque of 0.5 N·m maximum. Mounting screws are not supplied with the switch. 

- Use the M3 self-tapping screw, flat washer, and spring washer to tighten the IAC-R7 reflector to a torque of 0.5 to 0.6 N·m. 

- While optional reflector mounting bracket IAC-L2 is not supplied with mounting screws or nuts, the IAC-L3 and IAC-L5 are supplied with mounting screws for mounting the reflector on the bracket. 

- Reflector IAC-RS1 and IAC-RS2 can be installed directly on a flat surface using the adhesive tape attached to the back of the reflec tor. Before attaching the reflector, clean the board surface to ensure secure attachment.
