Photoelectric and inductive sensors

Baumer has introduced photoelectric and inductive sensors in hygienic and wash-down designs, specifically addressing the concerns of the food and beverage industry. The sensors offer thread-free V4A stainless steel housings, as well as mounting accessories that are also made of FDA-approved materials. A range of EHEDG-certified reflectors and Ecolab-approved IP69K cables are included for position detection in the food zone. For applications in the splash zone, Baumer also offers a new wash-down design. These sensors are as resistant against detergents and high-pressure splash water as those in hygienic design, but they are mounted using threaded connections, the company explains. One of the new products is the SmartReflect background-reflective photoelectric sensor, FNDH 14, which can use existing stainless steel machine parts as a reflector. Reducing the number of reflectors on a machine results in an easier installation and reduced maintenance and cleaning effort. The inductive sensors have an operating temperature range from -40 to 100 degrees C, offering versatile fields of application from the processing of frozen products to areas with clean in place processes.
