The robust and highly efficient light barriers in the O-50 Metal series work with visible red light LEDs or with laser light that is safe for the eye (laser class 1). They are robust and have a metallic housing and metallic plug. The sensors have maximum functional reserve and are used for long ranges.
Diffuse reflective sensors
Energetic retroreflective diffuse sensors are economic sensors with a transmitter and receiver in one housing. The working distance and the brightness of the object and background influence object detection, wherein bright objects can be recognized well against dark backgrounds.
Retroreflective diffuse sensors with background suppression provide reliable detection results with varying objects. They evaluate the position of objects, the objects located behind the set switching position are suppressed.
Retroreflective sensors make long ranges possible, with simple assembly and a high degree of system availability. The emitted light is reflected back by a reflector and evaluated in the retroreflective sensor.
