Retroreflective sensors bounce light off a fixed reflector and determine a target's presence when it breaks the beam. They have longer sensing distances than diffuse sensors but require alignment. Polarized retroreflective sensors improve detection accuracy by filtering out ambient light sources.

Retroreflective Sensors
Category Selection
Retroreflective sensors bounce light off a fixed reflector and determine a target's presence when it breaks the beam. They are easier to install and typically more cost-effective than through-beam sensors, and they offer longer sensing ranges than diffuse sensors. Polarized retroreflective sensors improve detection accuracy by filtering out ambient light sources, ensuring consistent and reliable performance even in difficult lighting conditions.
