It creates an invisible beam up to 50 feet that stops and reverses the gate if interrupted, preventing damage or injury. With an LED alignment indicator and a wide operating temperature range (-20°C to +60°C), it ensures reliable performance in diverse environments. Ideal for swing gates requiring dual sensor sets, it comes with a 1-year warranty for dependable security. ## Description Product Description The Sentry Photo Eye is a secondary safety device. It produces a beam between the 2 units. When the beam is broken it will keep the gate from closing. It requires wires to be connected to both units (20 gauge) for operation. Typically a swing gate needs two sets of photo eyes for the best area protection. One set of photo eyes pointing across the drive on the outside of the hinge post (A). The second set mounted across the drive at the point where the gate is fully opened (B). The photo eye must be installed where the gate does not break the beam. The primary unit (Receiver) should be installed close to the control box. The two units must face each other to establish the beam (maximum distance 50 feet). 1 year warranty covers defects in material and workmanship.
