ABB 6819/60-24-500

The ABB 6819/60‑24‑500 presence detector is designed to take the hassle out of lighting control by automatically turning lights on when people enter a room — and off after they leave. Combining passive infrared (PIR) motion sensing with brightness detection, it ensures lights operate only when needed: corridors, staircases, storage rooms, bathrooms or offices will no longer stay lit by mistake after use. By doing so, it helps reduce energy consumption and electricity costs while enhancing convenience and safety. sonepar.no+1

When installed on the ceiling (recommended height ~3 m), it detects walking persons up to ~8 m diameter area, and seated persons up to ~6.5 m. shop.in.abb.com The built-in relay handles up to 2300 W — sufficient for most lighting loads including LED fixtures — and switching behavior can be tailored: choose automatic ON/OFF, semi‑automatic, or even short‑pulse mode. sonepar.no+1

Installation is straightforward: the detector mounts via integrated spring‑bracket into standard ceilings (Ø 68 mm cut‑out), making it suitable for new builds or retrofits without visible wiring or bulky sensors. Configuration (delay time, light threshold) is accessible from the front — no need to open ceilings once set. Compared to manual switches or less sophisticated motion sensors, ABB 6819/60‑24‑500 offers reliable detection, mixed light & motion triggering (avoiding false activation at daylight), and professional‑grade build quality — a solid choice for anyone seeking smart, automatic lighting control for residential or commercial spaces.
