The Miller Edge OptiGuard monitored photo optic system provides thru-beam entrapment protection for door and gate operators. The emitter and receiver can be mounted vertically or horizontally to meet your safeguarding needs. When an obstruction interrupts the beam, a signal is sent to motor controls to stop and/or reverse motion. The durable mounting bracket/hoods offer additional protection against debris and serve as a weather and sun shield. Key components include an operating range of 100 feet and easy alignment through a visible beam of light.
