Description

This is a standalone PIR (passive infrared) motion sensor, decoded from the article code ALER N-B/B as an IP65, 120mm black unit. It detects body heat moving across its field and switches connected lighting on automatically, then off again after a set delay. It wires inline on a 220-240V AC mains supply and is built from black plastic, measuring 120 by 80 by 52mm.

The IP65 rating means it is sealed against dust and water jets, so it suits sheltered and exposed outdoor positions such as porches, driveways, garages and pathways, as well as indoor utility areas. Mount it at a height that gives a clear view of the approach you want covered, with adjustable time and ambient-light settings letting you tune how long the light stays on and the darkness level at which it activates. We also stock further PIR motion and daylight sensors to suit different load ratings and detection ranges.
