New stainless steel sensors stand up to harsh cleaning

Article Type: New products From: Sensor Review, Volume 31, Issue 3

Rockwell Automation has introduced two new families of photoswitches and inductive proximity switches designed to meet the demands of high-pressure jet spray wash down with corrosive cleaning agents and high temperatures. The 42CS photoelectric and the 871TS inductive sensor families meet the requirements of IP69K enclosure ratings. The housings are of 316L stainless steel.

Testing subjected the sensors to pressures to 102 kg/cm2 and temperatures to 80°C. They have also been successfully tested against many of the commonly used caustic cleaning agents and disinfectants used in the food and beverage industries.

An innovative ferromagnetic “teach” feature allows for adjustment without the liquid ingress associated with push button or potentiometer type adjustments. The photo switch family offers a variety of sensing modes including polarized retro-reflective, diffuse, transmitted beam, clear object detection and background suppression.
