Why Choose the Finder 18.31.0.024.0300 PIR Movement Detector?
The Finder 18.31.0.024.0300 is a compact passive infrared (PIR) movement detector designed for automatic lighting control in indoor installations. Part of the Finder 18 Series, it combines motion detection with an adjustable ambient-light threshold and time delay, making it suitable for energy-efficient lighting control in commercial, institutional and residential buildings.
Designed for a 24 V AC/DC supply, the detector provides a single normally open (SPST-NO) output contact rated up to 10 A. Its PIR sensing system provides a detection range of up to 8 m, while the adjustable light threshold allows switching to be dependent on surrounding illumination.
The 18.31.0.024.0300 is intended for indoor ceiling-mounted applications and offers an IP40 protection rating. Adjustable timing from approximately 10 s to 12 min allows the lighting-on period to be matched to the application, helping reduce unnecessary energy consumption in corridors, offices, stairways and similar areas.

Automatic PIR Lighting Control
The Finder 18.31.0.024.0300 detects movement by monitoring changes in infrared energy within its sensing area. When movement is detected and the measured ambient light is below the selected threshold, the detector operates its output contact to control connected lighting or associated control equipment.
Its adjustable time delay allows the connected load to remain active for a selected period after movement is detected. Combined with the adjustable light threshold, this provides an effective way to reduce unnecessary lighting use while maintaining convenient automatic illumination in occupied areas.
Typical Applications
- Automatic corridor lighting in offices and commercial buildings.
- Hotels and hospitality lighting-control systems.
- Hospitals and healthcare circulation areas.
- Schools and educational buildings.
- Stairway and common-area lighting.
- Office occupancy-based lighting control.
- Low-voltage building automation systems.
