The SICK W8 Series Photoelectric Sensor is a miniature sensor line designed for close-range applications. Autocollimation,
background suppression, and high switching frequencies of up to 2kHz make them ideal for a broad range of applications. The
W8 Series offers various standard detection principles, including the WTB8 proximity models, the WL8 and WLG8 retro-reflective models, as well as the WSE8 through-beam. The housing is designed with M3 threaded mounting holes that provide streamlined and secure mounting.
