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.

Applications

Teaching with No Workpiece Required -- Quick and Easy Setting

IP69K Degree of Protection with an SUS316L Housing

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

Detecting Plastic Bottles

Precautions for

Correct Use

The E3ZM-B@1/-B@6 are not applicable for detecting transparent objects that exhibit no birefringence, such as

glass bottles.

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.

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

The housing is constructed of corrosion-resistant SUS316L,

and the display cover is PES (polyethersulfone).

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.

This wide temperature range meets the needs of the many and diverse

applications in the beverage industry.

Ordering Information

Sensors

*1. Values in parentheses indicate the minimum required distance between the Sensor and Reflector.

*2. Models with a 5-m pre-wired cable are also available. When ordering, add the cable length to the end of the model number (e.g., E3ZM-B61 5M).

Accessories

Special Retroreflective Reflector

Note: Previous OMRON Retroreflective Reflectors (E39-R1/-R1S/-R2/-R3/-R9/-R10/-R1K/-RS1/-RS2/-RS3, etc.) cannot be used with the E3ZM-B.

*Values in parentheses indicate the minimum required distance between the Sensor and Reflector.

Mounting Brackets

*Cannot be used for Standard Connector models.

Sensor I/O Connectors

Note: The outer cover of the cable is made of PVC (polyvinyl chloride), the nut is make of SUS316L stainless steel, and the degree of protection is IP67 (IEC 60529).

When high-pressure washing will be used, select an I/O Connector that has IP69K degree of protection.

Ratings and Specifications

*1. For information on the P-opaquing function, refer to ➜ pages 1 and 8.

*2. Do not bend the cable in temperatures of −25°C or lower.

*3. IP69K Degree of Protection Specification

IP69K is a protection standard against high temperature and high-pressure water defined in the German standard DIN 40050,

Part 9. The test piece is sprayed with water at 80°C at a water pressure of 80 to 100 BAR using a specified nozzle shape at a rate

of 14 to 16 liters/min.

The distance between the test piece and nozzle is 10 to 15 cm, and water is sprayed horizontally for 30 seconds each at 0°, 30°,

60°, and 90° while rotating the test piece on a horizontal plane.

*4. Mounting Brackets must be ordered separately.
