Laser distance sensor DRL-12 aluminum, functioning as a motion sensor

Smart lighting control with DRL-12 sensor

DRL-12 is a laser distance sensor, ideal for automating lighting in corridors, staircases and other spaces where precise presence detection is important. It uses Time of Flight (ToF) technology to accurately measure distance, providing reliable operation and energy savings. The device is particularly useful in situations where light needs to be switched on only on stairs, ignoring movement in the surrounding area.

Functionality and application

The DRL-12 sensor offers a wide range of configuration options, tailored to different installation needs. Smooth adjustment of the detection range (0.1 – 2 m) allows for precise adaptation to the specific environment. The built-in brightness sensor prevents unnecessary lighting activation during the day, further increasing energy savings. The ability to directly control 12/24 V lighting circuits (up to 4 A) or cooperate with AS-225 controllers expands the range of applications. The soft on/off lighting function provides visual comfort and extends the life of light sources.

• Precise detection: ToF technology guarantees accurate distance measurement and reliable motion detection.
• Energy saving: The built-in brightness sensor eliminates unnecessary energy consumption during the day.
• Versatility: Ability to directly control lighting circuits or cooperate with AS-225 controllers.
• User comfort: Soft on/off lighting function provides smooth changes in light intensity.
• Compact dimensions: Mounting in a standard ø35 mm box facilitates installation and integration with existing infrastructure.
• LED indication: The LED indicates the operating status of the sensor, facilitating diagnostics and servicing.

Technical parameters and construction

The DRL-12 sensor is characterized by a solid construction and high quality workmanship. The housing made of aluminum ensures durability and resistance to mechanical damage. The device has screw terminals for connecting wires with a cross-section of 2.5 mm². Thermal protection protects against overheating, and the IP40 protection class provides resistance to dust. Thanks to the wide range of supply voltage (9-27 V DC), the sensor is compatible with various power systems. A wide range of front housing colors (aluminum, white, black and many other wood-like finishes) is available, allowing it to be matched to the interior design.

• Supply voltage: 9 – 27 V DC
• Maximum load current: 4 A
• Detection range: 0.1 – 2 m (adjustable)
• Trigger threshold: 2 – 500 lx (adjustable)
• Switch-on time: 0 – 10 min (adjustable)
