Photoelectric Beam Sensor
This is a Photoelectric Beam Sensor. Beam sensors operate by detecting when an object breaks a light beam between a transmitter and receiver. It is typically used for long-range object detection, access control, and perimeter security.
About sensors
Photoelectric Beam Sensor is listed under Sensors — proximity, photoelectric, ultrasonic, hall and limit sensors. Sensors in this category detect the presence or absence of objects without physical contact, or by contact in the case of limit switches. Proximity sensors, including inductive and capacitive types, respond to metallic and non-metallic objects respectively, typically within short ranges (1-50mm).
