REFLECTOR LIGHT BARRIER The photoelectric sensor emits an\ninfrared beam that is reflected back by the associated reflector and detected\nby the photoelectric barrier. If the beam is interrupted, the relay switches.\nThe maximum distance to the reflector is 4 metres. 2. Stable performance:\nthanks to integrated circuit technology and SMT surface mount technology, this\nnew generation of photoelectric barriers provides features such as delay,\npulse width modulation, external synchronization, anti-interference ability,\nhigh reliability, zone stability and intelligent self-diagnosis functions. 3.\nDistance adjustment: The distance can be adjusted to suit your needs via the\nknob. The device has infrared detection and high-precision sensitivity, with\nthe switching status indicated by an LED. The operation is simple and user-\nfriendly. 4. Easy installation: compact in size, versatile in function and\nwith fast response time. Included is a metal bracket for increased stability\nand easy installation. High quality flexible wiring prevents reverse polarity\nand provides polarity protection. 5. WIDE RANGE OF APPLICATIONS Whether for\nthe home and garden or industrial environments, our sensors cover a wide range\nof applications. They can be used as a signal transmitter for garage doors,\naccess gates and even for home and industrial automation systems. Technical\ndata: Material: ABS Detection method: mirror flexion Voltage: 12-24VDC Output\nType: Relay Output (NO\/NC) Cable length: 2 m. Detection range: 10-400mm\nOperating temperature: -30°C to +65°C. Waterproof: No Dimensions: 5 x 5 x 2\ncm. Note: The detection distance of this model is adjustable between 10-400\nmm. How to adjust the detection distance and sensitivity: There is an\nadjustment screw on the top of the sensor, turning clockwise increases the\ndetection distance or sensitivity, reducing counterclockwise rotation.
