Finder 18.41.8.230.0300 is a 110–230 V AC PIR corridor movement detector with a 30 m × 4 m sensing area and 10 A single-pole volt-free output contact for automatic indoor lighting control.

The Finder 18.41.8.230.0300 is a specialised passive infrared (PIR) movement detector for corridors and passage areas, designed to provide reliable automatic lighting control across long, narrow indoor spaces. As part of the Finder Series 18 movement detector range, it uses a dedicated optical system to provide an extensive rectangular sensing area particularly suited to hotel corridors, offices, walkways and communal passage areas.
The detector combines PIR movement sensing with a volt-free 1 NO output contact rated at 10 A. Adjustable sensitivity, ambient light threshold and switch-off delay settings allow operation to be tailored to the installation, while push-in terminals simplify wiring. Zero-crossing switching helps provide reliable control of modern lighting loads.
With a 110–230 V AC, 50/60 Hz supply and a sensing area of up to 30 m long × 4 m wide, the 18.41.8.230.0300 is specifically designed for ceiling installation in elongated spaces. It supports ceiling, suspended ceiling and recessed mounting, providing flexibility for both new installations and refurbishment projects.
PIR movement detectors such as the Finder 18.41.8.230.0300 detect changes in infrared radiation caused by people moving through the monitored area. When movement is detected, the output contact can automatically switch a connected lighting or control circuit, helping reduce unnecessary energy consumption while improving convenience and safety in frequently used passage areas.
Unlike general-purpose movement detectors with broadly shaped detection zones, the Finder 18.41 is specifically designed for long, rectangular spaces. Its optical system provides a sensing zone extending up to 30 m in length and 4 m in width, making it particularly effective for corridors and walkways where conventional PIR detectors may require multiple installation points.
