*1. 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).
*2. 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).
*3. 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.
*4. The Reflector is sold separately. Select the Reflector model most suited to the application.

*1. 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. 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 object on a horizontal plane.
