Using a super bright Infrared LED, the PZ series provides a very powerful light source and is ideal for operation in dusty, dirty environments. The beam of the PZ-51 and 51L, for example, can pass through 22 sheets of white paper, compared to conventional sensors that can only pass through 4 sheets. The PZ's high sensitivity makes it possible to detect minute objects down to 0.5 mm in width when used with an optional slit attachment. Waterproof construction makes the PZ series ideally suited for operation in food processing and other wet or washdown environments. If soiled by dirt or dust, etc., the PZ can be cleaned with water.
Flat lenses minimize dust and dirt collection.
LED indicators confirm stable operation. Because of its visible red LED beam spot, the detecting area can be checked to insure correct alignment. Additionally, the PZ-101 can easily distinguish between black and white targets. Since the emitted light will not diffuse, the target can be detected through a gap or opening in production or inspection lines. The sensor can be installed in narrow locations which are too tight for conventional sensors.
