Features 1、*Single Beam Infrared Sensor with high levels of anti-RFI / EMI capability. Anti-glare up to 50, 000 LUX, to avoid the impact of glare or car lights. 2、*Sealed design to anti-rain(fog), dust(worms) and other integrated weather, the detector sensitivity will increase automatically(AGC circuit). 3、*High-power transmitter, sensitivity surplus degree up to 90%. High-power infrared receiver tube, low-power process technology. 4、*Adjustable of beam interdiction period, to make it more flexible and adaptable. When interrupt, the relay output switch signal without voltage. 5、*Professional anti-jamming optical housing. 6、Single-beam infrared sensor with high RFI / EMI resistance. Anti-reflective protection up to 50,000 LUX to avoid glare or light from the car. 7、Sealed to protect against rain (fog), dust (worms) and other integrated weather conditions, the sensitivity of the detector is increased automatically (AGC circuit). 8、High power transmitter with increased sensitivity up to 90%. High power infrared receiver tube, low power process technology. 9、The adjustable beam time makes it more flexible and adaptable. In the event of an interruption, the relay output switch signal has no voltage. 10、Professional optical case with anti-trap protection. Specifications Note: It can work in distance between 2 meter to 15 meter, you can remove the lens cover when test in short distance to reduce the infrared focus. Overview: This is upgrade version of single beam sensor with latest LED light and more smt components compared 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 access control system, parking barrier, walking gate, vehicle gate and alarm system as body induction. It also can work as window, door and passageway anti-burglar detection or used in museum anti-theft.
