The perimeter light beam system is designed to meet safety standards for one-sided or multi-sided hazardous area and access protection. It can be used for safeguarding robotic work cells, automatic machinery work envelopes, assembly lines, and other manufacturing work cells.

The perimeter light beam system consists of a transmitter and receiver. Each is encased in a rigid, aluminum die-cast housing which makes them very durable. Communication between the transmitter and receiver is accomplished optically; no external controller is required. An invisible infrared beam of light is formed between the transmitter and receiver. Interruption of this beam of light sends a stop signal to the machine’s control. This signal is designed to stop hazardous machine motion or prevent the initiation of machine motion.

Mirrors increase the coverage of the safeguarded area. Two sides of a hazardous area can be safeguarded with the use of perimeter light curtain system and one mirror. Three sides of a hazardous area can be safeguarded by using one perimeter light beam system and two mirrors. (link to mirrors)

The perimeter light beam system is delivered ready for operation. Configuration settings are accessible from the front of the beams and can be changed while the system remains mounted.
