TAKEX Sensor, SEEKA Sensor’s Light Curtain sensors are specialized photoelectric devices that utilize two or more photoelectric beams. These 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)
