The emitter and receiver are aligned in a housing such that the retroreflective sensors are easy to install. Simply position a reflector on the opposite side and align the sensor with it. The standard version featuring a polarization filter combines the installation benefits offered by the retroreflective system with the reliable detection, even of reflective objects, at long detection ranges. The retroreflective sensors for clear object detection are ideal for reliably detecting transparent objects.
