18.A1.8.230.0000 Finder PIR External IP 55 1pole 10A 120/230V

Why Choose the Finder 18.A1.8.230.0000 External PIR Movement Detector?

The Finder 18.A1.8.230.0000 is an external PIR movement detector from the Finder 18 Series, designed for automatic lighting control in outdoor and moisture-prone environments. Its passive infrared sensing technology detects movement and operates connected lighting automatically, providing a practical solution for car parks, gardens, entrances and other external areas.

Designed for wall mounting, the detector provides a 110° sensing angle with an approximately 8 m detection range. The sensor body can be adjusted through 180° horizontally and 30° vertically, allowing the monitored area to be aligned with the requirements of the installation.

The Finder 18.A1.8.230.0000 operates from 120–230 V AC and provides 1 normally open 10 A output contact. Its IP55 protection rating, adjustable 5–1,000 lx ambient light threshold and 10 s to 20 min switch-off delay make it a flexible solution for automatic external lighting control.

Key Advantages

• IP55 protection makes the detector suitable for external installations.
• 120–230 V AC supply supports common mains-powered lighting systems.
• 1 NO 10 A output contact provides dependable load switching.
• 110° sensing angle and up to 8 m range provide effective movement coverage.
• Adjustable 5–1,000 lx ambient light threshold enables daylight-dependent operation.
• Adjustable 10 s to 20 min light-on time allows application-specific control.

Reliable PIR Detection for External Lighting Control

The Finder 18.A1.8.230.0000 detects changes in infrared radiation caused by people moving through its monitored area. When movement is detected, the output contact can automatically operate compatible lighting, reducing the need for manual switching while helping prevent lights from remaining unnecessarily energised.

Its IP55 construction and adjustable sensor orientation make the 18.A1 particularly suited to outdoor installations. Separate adjustments for the ambient light threshold and light-on time allow installers to tailor operation to the location, ensuring lighting responds appropriately to both movement and surrounding daylight conditions.

Typical Applications

• Car parks and external parking areas.
• Gardens and landscape lighting.
• Building entrances and access routes.
• Pathways and external walkways.
• Residential and commercial exterior lighting.
• Garages and covered outdoor spaces.
• Bathrooms, showers and other suitably installed moisture-prone environments.
