Overview

Highest reliability, maximum resistance and endless possibilities

The W4S-3 Inox Hygiene series of photoelectric sensors combines hygienic requirements based on EHEDG with best-in-class performance. These sensors are completely enclosed in a stainless steel housing and can be taught via a stainless steel teach button with a metal membrane. With built in protection for the sensor cable, no additional mounting brackets or mounting holes are required for in-process machine integration. These sensors are designed for a completely hygienic sensor solution that is a necessity for the most hygienic machines.
