These are wireless beams for gate motors from Gemini: the GEMINI IRB Set Wireless (part L90284), infrared safety beams rated for up to 10m. Here "wireless" means the transmitter runs on its own battery, with an LED to check the battery level, so it needs no cable back to the motor. The receiver is still wired to the motor on three wires: COM, IR BEAM and 12V+. They are made for Gemini gate motors such as the Gemini 12V 7Ah slider.
How these wireless beams for gate motors work
The two units face each other across the gate opening. The transmitter sends an infrared beam to the receiver, and the receiver, wired to the motor, signals the motor when an object or person breaks the beam. On this Gemini set the transmitter is battery powered, so only the receiver side needs cabling.
Wiring and lining up the receiver
Gemini's wiring diagram uses three wires from the receiver to the motor: COM, IR BEAM and 12V+. The receiver has a buzzer to help with alignment, plus an optional link for a low-battery buzzer. The Gemini wireless IRB manual is linked on this page. Alectra Solutions supplies the equipment only.
Range and size
Gemini rates the set for up to 10m. Gemini gives the weight as 0.2kg and the size as about 11.5 x 8.5 x 6cm. If you are replacing the motor's control board at the same time, see the Gemini V90 PCB.
