## **AC[3] : Auto Compensation Control for Contamination (Refer to page 9 for a technical description.)** a7 **Patented** 

Parameters require resetting when static electricity causes dust to adhere to the surface of the Sensor or Reflector, or when the light emission power drops due to temperature- or time-related changes. Original OMRON light emission control technology greatly reduces the resetting work involved.

**E3ZM-B** 

## **Teaching with No Workpiece Required -- Quick and Easy Setting** 

There is no need for delicate sensitivity adjustments. Simply adjust the optical axes of the Sensor and Reflector, then press the Teaching button twice. 

This high-reliability design eliminates worries about variations in the sensitivity settings of different operators. 

## **Industry Top** 

## **IP69K Degree of Protection with an SUS316L Housing** 

The housing is constructed of corrosion-resistant SUS316L, 

and the display cover is PES (polyethersulfone) or PEI (polyetherimid). Both materials are highly resistant to the effects of detergents and disinfectants. 

IP69K degree of protection also allows the E3ZM-B to withstand washing with high-temperature, high-pressure water. This makes the E3ZM-B well suited to use in sites requiring a high level of hygiene. 

## **A Wide Ambient Temperature Range of** − **40 to 60** ° **C** 

This wide temperature range meets the needs of the many and diverse applications in the beverage industry. 

## **Applications** 

## **Detecting Plastic Bottles** 

The E3ZM-B @ 1/-B @ 6 are not applicable for detecting transparent objects that exhibit no birefringence, such as **Precautions for** glass bottles. **Correct Use** Transparent objects made of resin also exhibit little birefringence, and cannot be detected with complete stability. Check the detection stability of objects such as these prior to actual operation.

## **Technical Descriptions**

## **New Technology for Detecting Transparent Objects Exhibiting Birefringence P-opaquing (Polarization-opaquing)** 

Conventional photoelectric sensors for detecting PET bottles depend on refraction due to the bottle's shape or on the attenuation of light intensity caused by surface reflection. However, it is difficult to attain a sufficient level of excess gain with these methods. 

**==> picture [210 x 225] intentionally omitted <==**

The E3ZM-B utilizes the birefringent (double refraction) property of PET bottles to dramatically increase the level of excess gain. The polarization component that is disturbed by the PET bottles as they pass along the line is cut by a special and unique OMRON polarization filter. This greatly lowers the intensity of the light received to provide stable detection with simple sensitivity adjustment. 

“P-opaquing” is a word that was coined to refer to the process of applying polarization in order to opaque transparent objects that exhibit the property of birefringence. 

The excess gain of the E3ZM-B is doubled for both light-ON and dark-ON applications.

are not equipped with functions to compensate for changes in the intensity of light received caused by dust and other lens-soiling matter, ambient temperature, and changes that occur in the LED over time. This makes it comparatively difficult to achieve long-term, stable detection of objects that exhibit little change in the intensity of light received, such as transparent objects. 

The AC[3] (AC cube) function provided on the E3ZM-B periodically feeds the intensity of light received during lightON operation back to the light-emitting circuit, to keep the intensity equal to the value set by teaching. 

This allows the E3ZM-B to attain long-term, stable detection while helping to cut down on maintenance requirements and improve the equipment operating ratio. 

Note: The AC[3] function cannot be used for dark-ON operation. 

Intensity of light received is compensated every 30 s. E3ZM-B

## **WARNING** 

**This product is not designed or rated for directly or indirectly ensuring safety of persons. Do not use it for such a purpose.** 

## **CAUTION** 

**Do not use the product with voltage in excess of the rated voltage. Excess voltage may result in malfunction or fire.** 

**Never use the product with an AC power supply. Otherwise, explosion may result.** 

**When cleaning the product, do not apply a high-pressure spray of water to one part of the product. Otherwise, parts may become damaged and the degree of protection may be degraded.** 

## **Precautions for Safe Use** 

The following precautions must be observed to ensure safe operation of the Sensor. 

## **Operating Environment** 

Do not use the Sensor in an environment where explosive or flammable gas is present. 

## **Connecting Connectors** 

Be sure to hold the connector cover when inserting or removing the connector. 

When using an XS3F Connector, be sure to tighten the connector lock by hand; do not use pliers or other tools. If the tightening is insufficient, the degree of protection will not be maintained and the Sensor may become loose due to vibration. The appropriate tightening torque is 0.3 to 0.4 N·m. When using another, commercially available connector, follow the usage and tightening torque instructions provided by the manufacturer. 

## **Load** 

Do not use a load that exceeds the rated load. 

## **Low-temperature Environments** 

Do not touch the metal surface with your bare hands when the temperature is low. Touching the surface may result in a cold burn. 

## **Oily Environments** 

Do not use the Sensor in oily environments. They may damage parts and reduce the degree of protection. 

## **Modifications** 

Do not attempt to disassemble, repair, or modify the Sensor. 

## **Outdoor Use** 

Do not use the Sensor in locations subject to direct sunlight. 

## **Cleaning** 

Do not use thinner, alcohol, or other organic solvents. Otherwise, the optical properties and degree of protection may be degraded. 

## **Cleaning** 

Do not use highly concentrated cleaning agents. Otherwise, malfunction may result. Also, do not use high-pressure water with a level of pressure that exceeds the stipulated level. Otherwise, the degree of protection may be reduced. 

## **Surface Temperature** 

Burn injury may occur. The Sensor surface temperature rises depending on application conditions, such as the ambient temperature and the power supply voltage. Use caution when operating or performing maintenance on the Sensor. 

## **Cable Bending** 

Do not bend the cable in temperatures of − 25 ° C or below. Otherwise, the cable may be damaged.

**E3ZM-B** 

## **Precautions for Correct Use** 

Do not use the Sensor in any atmosphere or environment that exceeds the ratings. 

## **Do not install the Sensor in the following locations.** 

- (1) Locations subject to direct sunlight 

- (2) Locations subject to condensation due to high humidity 

- (3) Locations subject to corrosive gas 

- (4) Locations where the Sensor may receive direct vibration or shock 

## **Connecting and Mounting** 

- (1) The maximum power supply voltage is 30 VDC. Before turning the power ON, make sure that the power supply voltage does not exceed the maximum voltage. 

- (2) Laying Sensor wiring in the same conduit or duct as highvoltage wires or power lines may result in malfunction or damage due to induction. As a general rule, wire the Sensor in a separate conduit or use shielded cable. 

- (3) Use an extension cable with a minimum thickness of 0.3 mm[2] and less than 100 m long. 

- (4) Do not pull on the cable with excessive force. 

- (5) Pounding the Photoelectric Sensor with a hammer or other tool during mounting will impair water resistance. Also, use M3 screws. 

- (6) Mount the Sensor either using the bracket (order separately) or on a flat surface. 

- (7) Be sure to turn OFF the power supply before inserting or removing the connector. 

## **Power Supply** 

If a commercial switching regulator is used, ground the FG (frame ground) terminal. 

## **Power Supply Reset Time** 

The Sensor will be able to detect objects 100 ms after the power supply is tuned ON. Start using the Sensor 100 ms or more after turning ON the power supply. If the load and the Sensor are connected to separate power supplies, be sure to turn ON the Sensor first. 

## **Turning OFF the Power Supply** 

Output pulses may be generated even when the power supply is OFF. Therefore, it is recommended to first turn OFF the power supply for the load or the load line. 

## **Load Short-circuit Protection** 

This Sensor is equipped with load short-circuit protection, but be sure to not short circuit the load. Be sure to not use an output current flow that exceeds the rated current. If a load short circuit occurs, the output will turn OFF, so check the wiring before turning ON the power supply again. The shortcircuit protection circuit will be reset. The load short-circuit protection will operate when the current flow reaches 1.8 times the rated load current. When using a capacitive load, use an inrush current of 1.8 times the rated load current or lower. 

## **Water Resistance** 

Do not use the Sensor in water, rainfall, or outdoors. 

## **When disposing of the Sensor, treat it as industrial waste.**
