Polarized Retroreflective Sensing Detects Shiny Objects 7m Sensing Range Selectable Light/Dark Operation 5 ms Response Time Infrared LED Emitter

Product description

The Allen-Bradley 42RLU-4200B is a polarized retroreflective photoelectric sensor designed for reliable object detection in challenging industrial environments. It operates on 102-132VAC with a power consumption of 2VA, utilizing an Infrared (IR) Emitter LED. This sensor features a sensing range of up to 7 meters and offers selectable light/dark operation with a quick 5 ms response time.

Polarized retroreflective sensors are particularly useful for detecting shiny objects that can cause false triggers with standard retroreflective sensors. Applications include automated material handling, packaging lines, and machine guarding where reliable detection of various surfaces is critical. Its robust design is suited for demanding industrial settings.
