Finder Type 18.A1 Infrared Motion Detector, 110-230V AC, 180° 12m Range, 1 NO 10A, IP54, White 18.A1.8.230.0000

In warehouses, stairwells, and building entrances, the Finder 18.A1.8.230.0000 infrared motion detector automatically switches lighting on when someone enters its detection zone and off after a set delay. It mounts on walls or ceilings and covers a wide 180° area up to 12 metres, making it suitable for both indoor and sheltered outdoor locations thanks to its IP54 rating.

Why choose it

The 18.A1 series combines a high switching capacity with flexible timing and lux settings, so you can fine-tune it to avoid false triggers from daylight or passing animals. Its robust IP54 housing withstands dust and moisture, while the UV-resistant material prevents yellowing over time. Installation is straightforward on standard wall boxes or directly on ceilings.

Ideal use cases

• Automatic lighting control in corridors, staircases, and storage rooms
• Entrance areas and driveways where lights should only operate at night
• Energy-saving retrofit in commercial and residential buildings
• Outdoor covered areas such as carports or porches

Good to know

For best coverage, mount the detector at the recommended height of 2.5 metres. The integrated relay can directly switch lighting loads up to 10 A, eliminating the need for an external contactor in most cases. The light sensitivity adjustment allows operation only in darkness or also during twilight, depending on your needs.
