Details
High-performance object detection at close range
The W8 is a high-quality, miniature photoelectric sensor family specially designed for close-range applications. Autocollimation, background suppression, and high switching frequencies of 2 kHz make these sensors ideal for a broad range of applications. The series is comprised of the WTB8 photoelectric proximity sensor, the WL8 and WLG8 photoelectric retro-reflective sensor and the WSE8 photoelectric through-beam sensor. The housing is designed with M3 threaded mounting holes that provide easy and secure mounting.
