Photoelectric sensors survive high pressure washdowns

December 12, 2012 // By Julien Happich
The QM26 and QMH26 photoelectric sensors from Banner Engineering are designed specifically for food and beverage and pharmaceutical industries.

The sensors' design considers Hazard Analysis and Critical Control Point (HACCP) principles for hygienic manufacturing processes. The QM26 is housed in a non-toxic 316L stainless steel housing, and can survive high pressure washdowns and temperature cycling, ranging from -30 to +60°C. The sensor is ECOLAB certified for inexhaustible sensor life in chemically cleaned environments and is intended for splash zone areas. The QM26 also features easy side-mounting for quick set-up and installation.

The QMH26 has all the advantages of the QM26, however, it is designed with minimal grooves and crevices, leaving no room for bacteria to hide and multiply. It is self-draining for clean-in-place (CIP) applications. The sensor’s hygienic mounting shape reduces contamination risk, making it a suitable sensor to place in contact zones. Both the QM26 and QMH26 operate in retroreflective, clear object and adjustable field background suppression mode. The QM26 also operates in opposed mode.
