Laser distance sensor drl-12, motion sensor, merbau-satin DRL-12-30

Smart lighting for stairs and corridors with DRL-12 sensor

The DRL-12 laser distance sensor is a modern solution for automatic lighting control in places such as corridors, stairwells or utility rooms. It utilizes Time of Flight (ToF) technology to precisely detect movement and turn on the light only when needed, which translates to energy savings and increased user comfort. Flush-mounted installation makes the sensor discreet and aesthetically integrated into the interior design.

Application and functionality

The DRL-12 sensor emits a laser light beam and measures the time it takes to return after reflecting off an obstacle. This allows it to precisely determine the distance to the object and then compare it to the set detection range. If a person appears within the sensor's range, the lighting is automatically turned on. This is an ideal solution for stairs, where traditional motion sensors may have problems with proper operation. The sensor is designed to ignore movement outside the stair area, eliminating unnecessary light switching.

Key features and benefits

• ToF technology: Provides precise distance measurement and reliable motion detection.
• Adjustable detection range: The ability to set the range from 0.1 to 2 meters allows you to adapt the sensor to specific installation conditions and user needs.
• Twilight sensor: Prevents the light from turning on during the day, which further increases energy savings.
• Adjustable hold time: Allows you to set the time the light remains on after a person leaves the detection area – from 1 second to 10 minutes.
• Direct circuit control: Ability to directly control lighting circuits 12/24 V (up to 4 A), as well as cooperation with AS-225 cascade controllers.
• Wide power supply voltage range: Compatible with 9-27 V DC installations.
• Availability of many front colors: Allows you to match the sensor to the interior design (aluminum, white and many others).
• Compact dimensions: Easy installation in a standard flush-mounted box with a diameter of 35 mm.

Technical specifications

The DRL-12 sensor is characterized by a solid construction and high quality workmanship. It has thermal protection and a protection class of IP20, which ensures its reliable operation even in difficult conditions. The maximum switching power is 50 W at 4 A. Adjustment of the brightness threshold allows you to adjust the sensor's sensitivity to the prevailing lighting conditions (range 2-500 lx). The external dimensions are 45 x 45 x 1.5 mm, and the internal (box) ø35 mm x 45 mm deep.

This sensor is not only a functional solution for installers, but also a convenient tool for end users looking for smart ways to manage lighting in their home or office.
