IR-20M infrared photocell sensor with 20m distance for sliding gate has been widely used in the sliding door access control system. Infrared photo beam is usually installed on both sides of the sliding door. One side is the transmitting end and the other side is the receiving end. When the infrared beam detects the person or the car passes by.will give a signal to the sliding door control system, the sliding door control system is better than the signal given by the infrared radiation, it will keep the door in a door open state, to ensure the safety of people or cars. It's best to place the Photocells as close to the gate as possible to reduce the chance of this happening. www.jutaigateaccess.com
