Retro-Reflective Photoelectric Sensor (ML100-55/95/102)

Description

The optical sensors of this series are suitable for both standard and demanding applications.
The series features a miniature housing design, two M3 metal-threaded mounting holes, and a highly visible LED status indicator.
Each device is equipped with a sensitivity adjuster and a light-on/dark-on switch for increased flexibility.
A wide variety of versions are available in both infrared light and red light with PowerBeam for easy alignment.
Special versions with BlueBeam are suitable for challenging applications like those in the solar and battery industries.
