42CS Photoelectric & 871TS Inductive Stainless Steel Sensors

Oct. 15, 2010
Rockwell Automation's photoelectric and inductive stainless steel sensors are IP69 rated for washdown applications in the F&B industry.

The 42CS photoelectric and 871TS inductive sensor families feature stainless steel construction, extended temperature ratings, and IP69K enclosure ratings. IP69K testing replicates the steam-cleaning process typically used in the food and beverage industry. This testing requires the sensors to withstand spray pressure up to 1,450 psi and temperatures up to 176°F (80°C).

 

The 42CS sensor features a choice of smooth or threaded 0.7 in. (18 mm) 316L stainless steel housing with a hard plastic lens for enhanced reliability and long service life, as well as an operating temperature range of -13 to 185°F (-25 to 85°C). Smooth barrel models are designed to minimize the accumulation of undesired particles on the sensor’s body and to allow easier cleanup. An innovative ferromagnetic teach feature minimizes the possibility of water ingress associated with the use of push-button or potentiometer adjustment. This feature, offered on select sensing modes, allows users to easily adjust and optimize the sensing range to meet specific application demands.

 

The 42CS sensor family offers polarized retro-reflective, diffuse, transmitted beam, clear object detection, and background suppression sensing modes. A background suppression sensor is specially designed to detect shiny objects that often go undetected by other such sensors if the object is approaching at a slight angle. A stainless steel bracket is offered for mounting of smooth-barrel sensors.

 

The 871TS inductive proximity sensors feature a stainless steel 316L barrel and an FDA-certified polyphenylene sulfide plastic face that protects against chemicals and other corrosive agents. Sensors are offered in 0.5 and 0.7 in. (12 and 18-mm) diameter threaded cylindrical enclosures with an operating temperature range of -40 to 176°F (-40 to 80°C). For added application flexibility, standard and extended-range units are available.
