The DRL-12 is a laser sensor designed to control lighting, especially in corridors and staircases.
Precise detection setting from 0.1 to 2 m, direct load up to 50 W / 12 V DC, cooperation with AS-225 controllers, built-in brightness sensor.
The principle of operation is to emit a light beam and measure the delay of returning light as a result of reflection from an obstacle. On this basis, it is possible to precisely determine the distance to the obstacle, which is then compared with the set detection range. If something appears at a distance of less than the set value, the light will be switched on. This solution is perfect for switching on lighting circuits for example on open stairs, where it is important that the sensor detects presence only on the stairs and ignores everything that happens outside.
