Sygonix SY-5251904 Rilevatore di movimento PIR a soffitto da incasso 360° relè bianco

In an office corridor or open-plan workspace, the Sygonix SY-5251904 recessed ceiling motion detector automatically switches lighting when someone enters the room, then turns it off after an adjustable delay. Its 360° detection angle covers the area below the sensor, making it suitable for mounting in suspended ceilings at heights from 2.2 to 4 metres.

Why choose it

The detector is designed for recessed ceiling installation and blends into the ceiling with a white finish. It uses a relay output, which allows it to switch a wide range of lighting loads directly. The time delay and light sensitivity are adjustable to match the room's usage and ambient light conditions.

Ideal use cases

• Automatic lighting control in corridors, stairwells, and open offices
• Energy saving in areas with intermittent occupancy
• Replacement for existing recessed ceiling motion detectors

Good to know

The detector is intended for indoor use only (IP20). It requires a 90 mm installation opening and a connection to 220–240 V AC mains. The PIR sensor responds to moving heat sources, so it works best when people walk through the detection zone.
