Photobeam Sensors

OPTEX photobeam sensor is an opposing-type system in which the transmitter emits an infrared beam and the receiver, positioned opposite, receives it. When a person or object physically interrupts this beam, the system instantly detects the intrusion and triggers an alarm.
These sensors serve as a critical component in security systems, allowing for rapid detection and seamless integration with alarms and surveillance cameras to ensure immediate response.
