DRL-12:DRL-12 Laser Distance Sensor

The DRL-12 is a laser sensor designed for lighting control, especially in corridors and stairwells.
Precise detection adjustment from 0.1 to 2 m, direct load up to 50 W / 12 V DC, cooperation with AS-225 controllers, integrated brightness sensor.

## Operation

The operating principle involves emitting a light beam and measuring the delay of the returning light after reflection from an obstacle. Based on this, the distance to the obstacle can be precisely determined, which is then compared with the set detection range. If something appears at a distance less than the set value, the light turns on. This solution is perfect for switching on lighting circuits, for example, on open staircases, where it is important for the sensor to detect presence only on the stairs and ignore everything happening outside.

## Technical Characteristics

- ToF (Time of Flight) type laser distance sensor;
- The detection range can be smoothly adjusted from 0.1 to 2 m;
- a brightness sensor that prevents the light from turning on when the brightness level is high;
- adjustable light-on time;
- possibility of directly controlling 12/24 V lighting circuits (load capacity up to 4 A, which can be increased by connecting LED amplifiers
- LAMP);
- soft start and soft shutdown function available for controlled lighting circuits*;
- ability to activate AS-225 cascaded controllers;
- compact dimensions, can be mounted in a ø35 mm box supplied with the sensor;
- LED indicating the operating status of the sensor;
- thermal protection against exceeding the acceptable temperature inside the housing.
