سنسور خطی لیزری مادون قرمز ABO-20 با قابلیت تشخیص تا 20 متر

DC 12-24V Waterproof Outdoor Digital Photo Beam Sensor Active Single Infrared Beam Sensor: Single beam active intruder infrared detector with built-in AGC control circuit. The product can effectively prevent the interference from sunlight. the cell-shaped detector has beautiful structure with samll size. It is easy to be installed at wall, door, window, balcony, garage and other places.

Working principle: Infrared Beam Sensor is full named in "Active Infrared Intruction Detectors" . It mainly includes transmitter, Receiver, Beams, LED light, Lens and so on. The detection pnnciple is by using the LED infrared emission diode tread infrared pulse, then by the optical mirror focusing the light spread to deal with the far distance, last the receive get the infrared light. Then the infared pulse beam is blocked, it will alert. lnfrared is not-visible light, and will spread out; after emission, in the initial stages of the path will form a cone beam; with the increase of transmission distance , ideal emission intensity and the distance is inverse square attenuation of of of light.
