PRINCIPLE:This infrared detector emits a switching signal through the built-in relay operation. When the emitted infrared beam is blocked, the relay will send a switching signal, and the signal can be set to normally open or normally closed. SMALL VOLUME:The infrared sensor with small volume, maximum detection distance up to 20 meters. EXTENSIVE APPLICATIONS:The simple beam alarm photoelectric has extensive applications, available for road gates, automatic door, mechanical operation safety protection, access control, security system and more INSTALLATION:When installation the garage door sensor, first install the receiver, and then install the transmitter.
