The Reflecti-Guard™ Photo Optic Sensor is a non-contact safety device. It will detect the presence of an obstacle when the infrared light beam is interrupted, providing a safe means of stopping and/or reversing a gate’s motion. A single unit houses the light emitter and receiver, and can be configured for relay or pulsed signals. A beam of light is sent from the emitter to a reflector that sends the light beam back to the receiver.

Reflecti-Guard’s rugged, waterproof NEMA4 housing makes it suitable for both indoor and outdoor installations, such as tollbooths or parking lots. It can span up to 100ft.

Before designing or motorizing any gate, be sure to read and understand the ASTM-F2200 standard for gate construction. Additionally, since 2009, the International Building Code (IBC-2009) has required compliance with the current UL 325 safety standard.
