SICK WL150-P420 Photoelectric Retro-Reflective Sensor (6020688)

The SICK WL150-P420 is an ultra-compact photoelectric retro-reflective sensor with a dual-lens system and integrated polarisation filter, engineered for the precise detection of transparent materials such as glass and plastic films. It delivers a sensing range of 0.01 m to 0.6 m, optimized for close-range applications in packaging, bottling, and automation environments.

Its miniature rectangular housing, M8 connector, and selectable light/dark switching make it an ideal solution for OEM designs and machines with limited space. Supplied with a PL20A reflector and BEF-W150-A mounting bracket, it’s ready to install out of the box.
