12v Waterproof Infrared Photocell Gate Door Ir Sensor Automatic Barrier HenceActive Photoelectric Single infrared Beam Sensor Barrier Detector Alarm System Features: This is upgrade version of single beam sensor with latest LED light and more smt components compare with the old 3 lights handmade model, it's more stable and reliable. When interrupt the infrared, the relay will output switch signal, it can work for parking barrier, walking gate, vehicle gate as body induction. It also can work as window, door and passageway anti-burglar detection. 1. It can work in distance between 2meter to 15meters, when use in short distance, because the infrared is too strong to break, then you should remove the lens cover can work properly. 2. when interrupt, the relay output switch signal without voltage. 3. It has N/O and N/C switch. 4. It can work with access control system, parking barrier and alarm system etc. 5. It works with 12V power supply. Specification: 1.
