Photoelectric sensors consist of a light emitter and a receiver in a single housing. When the target material interrupts the light beam, the receiving unit detects the reduced light intensity and turn on the sensor.
Photoelectric sensors are well suited for general position- and presence-detection in almost any industry. These self-contained photoeyes are ideal for demanding industrial environments including small parts detection, distance detection, check for absence or presence of objects, sorting metallic & non-metallic objects, placement inspection, pin inspection, and reliable detection of transparent objects.
