**E3ZM** 

## **Structural Design That Provides Excellent Environment-resistance*** 

Indicator cover: Polyetherimide (PEI) 

Excellent resistance to detergents and disinfectants. 

## Waterproofing ring: Fluorine rubber 

Excellent resistance to detergents and disinfectants. 

Optical plate: Polymethylmethacrylate (PMMA) 

Excellent resistance to detergents and disinfectants. High transparency and other qualities give PMMA excellent optical characteristics. 

Sensitivity adjustment and mode selector switch: Polyetheretherketone (PEEK) 

Excellent resistance to detergents and disinfectants. Also has excellent abrasion resistance. 

Case: SUS316L 

Excellent corrosion resistance to many chemical reagents. 

## Seal 

The seal provides the durability to high-temperature and high-pressure water that complies with IP69K. 

## Cable: Polyvinylchloride 

Excellent resistance to detergents and disinfectants. 

*Do not use the E3ZM in an oily environment. 

## **Unique Members of the E3ZM Family** 

## **BGS Reflective Models** 

## **E3ZM-LS6** @ **H/-LS8** @ **H** 

Three models with different fixed sensitivity (rated sensing distances) have been created. These models cover the sensing ranges of the E3ZLS61.

## **Through-beam Inner Aperture Models** 

## **E3ZM-T63** 

Fine beam without attaching an external aperture. This eliminates malfunctions from residual water drops, even immediately after washing. 

## **A Better Fit for the Application** 

The E3ZM can be used in those harsh cleaning environments in which the E3Z was difficult to use. E3ZM passed the material resistance tests and is certified by Ecolab.

* IP69K Degree of Protection Specifications 

IP69K is a protection specification stipulated by DIN 40050 Part 9 of the German standards. 

The test item is sprayed with 80°C water from a nozzle of a specified shape at a water pressure of 80 to 100 bar. The amount of water is 14 to 16 liters per minute. 

The distance between the test item and the nozzle is 10 to 15 cm. The water is discharged at angles of 0°, 30°, 60°, and 90° from the horizontal plane for 30 seconds at each angle while the test item is rotated horizontally.

* Models numbers for Through-beam Sensors (E3ZM-T@@) are for sets that include both the Emitter and Receiver. 

The model number of the Emitter is expressed by adding "-L" to the set model number (example: E3ZM-T61-L 2M), the model number of the Receiver, by adding "-D" (example: E3ZM-T61-D 2M.) Refer to Ordering Information to confirm model numbers for Emitter and Receivers.

## **Safety Precautions** 

**Refer to** _**Warranty and Limitations of Liability**_ **.** 

## **Load** 

## **WARNING** 

**This product is not designed or rated for 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.** 

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. 

## **Rotation Torque for Sensitivity Adjustment and Selector Switch** 

Adjust with a torque of 0.06 N·m or less. 

## **Oily Environments** 

Do not use the Sensor in oily environments. 

## **Modifications** 

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

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

**High-temperature environments may result in burn injury.** 

## **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. 

## **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. 

## **Washing** 

Do not use highly concentrated detergents. They may cause malfunction. Do not use high-pressure water spray in excess of the specifications. 

## **Surface Temperature** 

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

## **Connecting Connectors** 

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

If the XS3F is used, always tighten the connector cover by hand. Do not use pliers. 

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. 

If other commercially available connectors are used, follow the recommended connector application conditions and recommended tightening torque specifications. 

**13** 

**E3ZM** 

## **Load Short-circuit Protection** 

## **Precautions for Correct Use** 

## **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 high-voltage 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 (sold separately) or on a flat surface. 

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

## **Cleaning** 

Never use thinner or other solvents. Otherwise, the Sensor surface may be dissolved. 

## **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. 

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 short-circuit protection circuit will be reset. The load shortcircuit protection will operate when the current flow reaches 1.8 times the rated load current. When using a C load, use an inrush current of 1.8 times the rated load current or higher. 

## **Water Resistance** 

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

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

## **Resistance to Detergents, Disinfectants, and Chemicals** 

- Performance is assured for typical detergents and disinfectants, but performance may not be maintained for some detergents and disinfectants. Refer to the following table when using these agents. 

- The E3ZM passed testing for resistance to detergents and disinfectants performed using the items in the following table. Refer to this table when considering use of detergents and disinfectants.

- Models numbers for Through-beam Sensors (E3ZM-T@@) are for sets that include both the Emitter and Receiver. The model number of the Emitter is expressed by adding "-L" to the set model number (example: E3ZM-T61-L 2M), the model number of the Receiver, by adding "-D" (example: E3ZM-T61-D 2M.) Refer to Ordering Information to confirm model numbers for Emitter and Receivers.
