18.31.8.230.0000 Finder PIR 1pole 10A 120/230V Voltage output

Why Choose the Finder 18.31.8.230.0000 PIR Movement Detector?

The Finder 18.31.8.230.0000 is a reliable passive infrared (PIR) movement detector designed for automatic lighting control in indoor installations. Part of the Finder 18 Series, this detector combines 360° movement sensing with adjustable sensitivity, timing and ambient-light control to provide efficient automatic switching in commercial, institutional and residential buildings.

Operating from a 120–230 V AC, 50/60 Hz supply, the 18.31.8.230.0000 uses a voltage output and provides single-pole switching with a 1 NO (SPST-NO), 10 A output. Its PIR sensor offers a maximum detection diameter of approximately 8 m, making it well suited to ceiling-mounted lighting control in rooms, corridors and circulation areas.

The detector incorporates an adjustable operating delay of approximately 10 s to 12 min and adjustable detection sensitivity, allowing its response to be matched to the installation. With an IP40 protection rating and operating temperature range of -10 to +50 °C, it provides a compact solution for dependable indoor occupancy-based lighting control.

Reliable Automatic Lighting Control

The Finder 18.31.8.230.0000 uses passive infrared technology to detect movement within its coverage area. When qualifying movement is detected, the device operates its voltage output to switch the connected lighting or associated control circuit, providing automatic illumination without requiring conventional manual switching.

Its ceiling-mounted 360° sensing arrangement provides broad coverage, while adjustable sensitivity and timing allow installers to optimise operation for the surrounding environment. These functions make the detector particularly useful where automatic lighting can improve convenience while reducing the amount of time lights remain switched on unnecessarily.

Typical Applications

• Automatic office and workplace lighting.
• Corridors, hallways and circulation areas.
• Stairways and building common areas.
• Schools and educational buildings.
• Hotels and hospitality facilities.
• Commercial and retail premises.
• Residential common-area lighting.
• Energy-efficient occupancy-based lighting systems.
