These red-light sensors in the compact plastic housing facilitate robust object detection for homogeneous or similar objects. Through the simple sensitivity adjustment with two-level teach (object/background), they are particularly flexible in use. These sensors feature the A^2LS active ambient light suppression and easy alignment through brightly visible brightVision light spot. Available for high object color independence even with infrared.

Advantages:
Energetic diffuse reflection sensor with light/dark switching
Scanning range adjustment via teach-in
Simple mounting with integrated M3 metal threaded sleeves
Compact installation possible due to cable outlet at the rear or bottom
Full control through green and yellow indicator LEDs and complementary outputs
Robust plastic housing acc. to IP 67 for industrial application
Infrared version for high color independence
