Light Curtain sensors are specialised photoelectric devices that utilise two or more photoelectric beams.
Light Curtain sensors use through-beams (a separate sending and receiving unit) or Reflectors (a sending unit and a reflector).
These units are suitable for detection of larger areas where the detection of objects ranging from the retrieval of parts in a pick-bin to a person entering the area of a robot is non-specific and a wide area must be covered.
Specialized Light curtains are available for; Parts Counting, Human and Machine Safety Applications and multi-plane object detection (J-Series).
