Stainless Steel Housing (Compact Photoelectric Sensor with Built-in Amplifier)
E3ZM
Features
Withstands Detergent and
Disinfectant Spray
Superior Protective Structure
Shape and Markings Designed
for Greater Hygiene
We used SUS316L for the case and
the best material for all parts to
achieve 200 times the durability of
the E3Z (in 1.5% solution of sodium
hydroxide at 70˚C) to make the
E3ZM suitable for the cleaning
conditions of food-processing
machinery.
The first IP69K* (DIN 40050-9)
protective structure in the world
for a square metal photoelectric
sensor. Suitable for high-
temperature, high-pressure jet
water spray cleaning applications.

Few indentations in the shape
means less dust and water can
collect, making the E3ZM more
hygienic. No labels have been used
in order to prevent foreign matter
contaminating food products. The
E3ZM model and lot numbers are
imprinted using a laser marker.

Ordering Information
Sensors
*1. The Reflector is sold separately. Select the Reflector model most suited to the application.
*2. Values in parentheses indicate the minimum required distance between the Sensor and Reflector.
*3. Pre-wired Models with a 5-m cable are also available for these products. When ordering, specify the cable length by adding "5M" to the end of the model number
(e.g., E3ZM-LT61 5M).
M12 Pre-wired Connector Models are also available. When ordering, add "-M1J" to the end of the model number (e.g., E3ZM-R61-M1J 0.3m).
*4. M8 Connector Models are also available with three-pin connectors. When ordering, add "-M5" to the end of the model number (e.g., E3ZM-T66-M5).
This does not apply to BGS Reflective Models, however, because they require 4 pins.
*5. Through-beam Models are also available with a light emission stop function. When ordering, add "-G0" to the end of the model number (e.g., E3ZM-T61-G0).
Accessories
Reflectors
Note: When using a Reflector without a rated value, use 0.7 times typical value as a guideline for the sensing distance.
* Values in parentheses indicate the minimum required distance between the Sensor and Reflector.

Ratings and Specifications
* 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.
