SICK Retroreflective Photoelectric Sensor, Rectangular Sensor, 4 → 120 mm Detection Range IO-LINK

W4 miniature photoelectric sensors and photoelectric proximity sensors are the ideal solution for the intelligent automation of industrial processes. The powerful sensors in the miniature housing reliably detect glossy, flat, uneven, perforated and transparent objects and detect a wide range of parameters such as remission and distance values.

Due to the selection of different designs, housing materials and light sources, the sensors are well-suited to countless applications and nearly any assembly situation. The profile is rounded out with an intuitive operating concept and intelligent diagnostic functions.
