BWP Series Slim Plastic Body Area Sensors The BWP series area sensors feature a flat and compact body size (13 mm) made of high strength PC/ABS (Polycarbonate/Acrylonitrile Butadiene Styrene) plastic. The sensors use high performance Fresnel lens and have high-speed response time of under 7 ms. Four different configurations are available based on the number of optical axes and detection area size. Light ON and Dark ON operation modes switching is available. The series also features various user-friendly functions including operation test function and mutual interference prevention functions.
