What are gate automation photocells and what’s their function? Infrared photocells Automatic gates open and close when instructed by a variety of methods. Remote transmitters are carried by gate owners to operate their gates at the push of a button on the remote. Access control systems use gate release buttons inside the property to open the gates. And keypads or proximity readers installed outside the gates allow access for anyone with the code or programmed proximity tag. It is also possible to bury a loop cable in the driveway inside the gates that operates the gates when a vehicle passes over it. Under normal conditions, automatic gates open when instructed to do so and then close after a certain period of time. However, moving gates should not be allowed to hit anything or anyone, so a way to tell them that something is in their path is needed. This is what safety photocells are for. Photocells come in pairs and function by sending an infrared beam from one...
