Why Choose the Finder 18.31.8.230.0300 PIR Movement Detector?
The Finder 18.31.8.230.0300 is a versatile passive infrared (PIR) movement detector designed for automatic lighting control in commercial, industrial and building automation applications. Part of the Finder 18 Series, this detector combines infrared movement sensing with a potential-free output contact to provide reliable control of lighting and other suitable electrical loads.
Designed for flush or ceiling mounting, the 18.31.8.230.0300 provides a discreet installation for indoor environments. Its PIR sensor offers a detection area of up to 8 m diameter, while adjustable sensitivity, light-level control and timing allow operation to be configured for different rooms and occupancy patterns.
With a 120–230 V AC supply, single normally open 10 A output contact and an adjustable switch-off period from 10 s to 12 min, the Finder 18.31.8.230.0300 provides an effective solution for automatically switching lighting according to movement and ambient light conditions.

Reliable PIR Control for Automatic Lighting Systems
PIR movement detectors monitor changes in infrared radiation caused by people moving within their detection area. The Finder 18.31.8.230.0300 uses this technology to switch connected lighting or other suitable loads automatically, reducing the need for manual switching and helping minimise unnecessary energy consumption.
The integrated light-level adjustment allows switching to be dependent on ambient illumination, while adjustable sensitivity and timing provide additional control over detector operation. The potential-free output contact also provides flexibility when integrating the detector into compatible lighting and building control circuits.
Typical Applications
- Office and commercial building lighting.
- Corridors and communal areas.
- Stairways and circulation spaces.
- Hotels and hospitality facilities.
- Industrial and commercial premises.
- Energy-efficient automatic indoor lighting systems.
