## Protective measures against aggressive chemicals 

The E3ZM family of high grade stainless steel sensors has been designed with the goal to achieve long sensor lifetime in frequently cleaned environments. 

High grade SUS 316L housings provide high resistance to aggressive chemicals but the lifetime of a sensor is not only determined by the case material. The design quality is determined by the resistance against detergents of the complete protective structure. When designing a sensor, potential weak points are the material selection and areas where 2 materials connect e.g. the lens, cable entry or the potentiometers. The materials and design structure for the E3ZM have been intensively researched and tested to provide high detergent resistance and sensor lifetime in daily operations compensating for mechanical and temperature stress, high pressure water and aggressive chemicals.

## Protective measures against water ingress 

The family of E3ZM photoelectric sensors is designed and tested for highest protection against water ingress. For achieving the best protection in frequently cleaned environments and to prevent potential errors during installation and operation, refer to the recommendations below. 

## 1. Using pre-wired models 

The pre-wired models are manufactured to provide highest protection against water ingress both at the sensor and via the cable. 

## **RECOMMENDATION:** 

Use pre-wired versions if protection against water ingress is key and frequent replacement of the sensor is not expected 

## 2. Using M8 connector models 

Connector models are often preferred to allow an easy exchange of the sensor. When using M8 connector models, observe the recommended mounting torque (see page 10). A too tight connection may damage the sealing ring and a loose connection  may provide an opportunity for water to enter into the connection between sensor and connector. 

Highest protection 

Fast exchange 

## 3. Using a M12 or M8 pigtail connector 

Using a pigtail cable connector with 30 cm of PVC cable and an M8 or M12 plug combines the highest protection against water ingress of the pre-wired version with the flexibility of the connector models for easy exchanging the sensor. In general the M12 connectors provide an enhanced protection against installation errors compared to M8 connectors. Highest protection Additionally the XS5 click connectors aland fast exchange 

In general the M12 connectors provide an enhanced protection against installation errors compared to M8 connectors. Additionally the XS5 click connectors always ensure that the correct tightening torque is applied for optimal protection. **RECOMMENDATION:** 

Use pigtail connectors for the best combination of protection and flexibility for exchanging the sensor. 

For ordering pigtail connectors contact your OMRON representative. 

**RECOMMENDATION:** 

To obtain the correct mounting torque, a torque wrench may be used.

Safety Precautions 

## **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.** 

**==> picture [34 x 115] intentionally omitted <==**

**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 or preferably with a torque wrench; do not use other tools. If too much tightening torque is applied the degree of protection will not be maintained. 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. 

## **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. 

When using another, commercially available connector, follow the usage and tightening torque instructions provided by the manufacturer.
