The Finder 18.11.8.230.0000 is a compact PIR movement detector for external surface mounting, designed for automatic control of lighting and electrical loads in residential, commercial and industrial environments. Part of Finder's Series 18, it combines passive infrared movement detection with an integrated light sensor and adjustable operating parameters.
Operating from a 110–230 V AC, 50/60 Hz supply, the detector uses a single normally open output contact rated at 10 A. Its PIR sensing system provides a detection angle of 110° and a maximum detection range of approximately 10 m, allowing lighting or other suitable loads to be activated automatically when movement is detected.
The 18.11 features adjustable switch-off delay and ambient light thresholds, allowing operation to be tailored to the installation. With an IP55 protection rating and an operating temperature range of -10 °C to +50 °C, it is designed for wall and surface mounting in both indoor and appropriate outdoor locations.
PIR movement detectors monitor changes in infrared radiation caused by people moving through their detection area. The Finder 18.11 uses this principle to operate its output contact automatically, making it particularly useful for lighting circuits where lights should switch on when an area is occupied and switch off after movement has ceased.
The integrated light sensor allows the detector to respond according to ambient illumination as well as movement. By adjusting the 5–350 lx light threshold and 10 s to 12 min switch-off delay, installers can configure the detector to suit corridors, entrances, storage areas and other locations while avoiding unnecessary operation when sufficient natural light is available.

The Finder 18.11.8.230.0000 is a PIR movement detector used to switch lighting or other compatible electrical loads automatically when movement is detected.
The detector operates from a 110–230 V AC, 50/60 Hz power supply, covering common 120 V and 230 V mains applications.
The 18.11 has one normally open output contact rated at 10 A. The permissible load depends on the type of lighting or electrical equipment being switched, so Finder's load ratings should be observed when selecting the connected load.
The PIR sensor provides a 110° detection angle with a maximum detection range of approximately 10 m, subject to mounting position and installation conditions.
The detector has an IP55 protection rating and is designed for external surface mounting, making it suitable for appropriate outdoor locations when installed in accordance with Finder's mounting instructions.
Finder Series 18 movement detectors combine PIR sensing, adjustable light-level control and configurable timing to provide practical automatic lighting control for residential, commercial and industrial installations.
