Overview: This is an upgraded version of single beam sensor with the latest LED light and more smt components compared to the old handmade 3 lights model, it is more stable and reliable. When it interrupts the infrared, the relay will output a switching signal; it can work for access control system, parking barrier, vehicle access barrier, vehicle gate and alarm system as body induction. It can also work as window, door and passage anti-burglary detection or used in museum anti-theft.Features:* Single beam infrared sensor with high levels of anti-RFI/EMI capability.* Anti-glare up to 50,000 LUX, to avoid glare or car lights.* Waterproof design against rain (fog), dust (worms) and other bad weather, the detector sensitivity will automatically increase (AGC circuit).* High power transmitter, excess sensitivity degree up to 90%.* High power infrared receiver tube, low power processing technology.* Adjustable beam ban period, to make it more flexible and adaptable.* In case of interruption, the relay output switching signal is voltage-free.* Professional anti-jamming optical box.Specifications:Power supply: 12V 24V DC / ACInput: RX 15mA - TX 30mAFrquency Infrared: 1.92KhzWavelength: 940nmWorking Range: 2-15mDetection Distance: 20m (Open Area)Switch: N/O & N/C OptionalWork with: Access Control System / Parking Barrier / Alarm System, etc.Working Temperature: -30 C + 50 CItem Size / Each: 78 * 50 * 30mm (D * W * H)Item Weight (with case) / Each: 36gPackage Information:Package Size: Approx. 13.8 * 8.4 * 4.5cm / 5.4 * 3.3 * 1.8inPackage Weight: Approx. 125g / 4.4ozPacking List:1 * Pair of Beam Sensors1 * Set of Mounting Screws
