STEINEL Hallway COM1 High-Frequency Flush-Mount Presence Detector, White (86503)

In hallways, corridors, and stairwells, lights often stay on far longer than needed—wasting energy and driving up costs. The STEINEL Hallway COM1 solves this by detecting presence through high-frequency technology, even through thin walls or panels, ensuring lights activate only when someone is actually there.

Who is it for

This flush-mount presence detector is ideal for building owners, facility managers, and electricians who need reliable, automatic lighting control in indoor spaces like corridors, stairwells, offices, and hallways. It suits both new installations and retrofits where a discreet, recessed sensor is preferred.

Main features

• High-frequency (HF) sensor technology at 5.8 GHz detects motion through non-metallic materials, enabling hidden installation.
• 360° detection angle with adjustable radial reach from 1 to 8 m and tangential reach up to 10 m.
• Flush-mount (Unterputz) design for seamless integration into ceilings or walls.
• Adjustable time setting from 30 seconds to 30 minutes, plus pulse mode for staircase lighting timers.
• Twilight level adjustable from 10 to 1000 lux, so lights only switch on when needed.
• High switching capacity: up to 2000 W resistive load or 1000 W for LED/fluorescent lighting.
• Low standby power consumption of less than 1 W.

Tips

For best performance, install at a height of about 2.8 m. Since the HF signal can penetrate thin walls, you can mount the detector behind a suspended ceiling or inside a luminaire for a completely hidden look. Use the pulse mode when connecting to a staircase time switch.
