Knightsbridge Recess Mount 5.8GHz HF Motion Sensor – White

Description

The Knightsbridge OSHFREC is a recess-mount 5.8GHz high-frequency motion sensor designed to automate lighting in corridors, stairwells, storage rooms and other spaces where hands-free control improves convenience and energy efficiency. The sensor sits flush in the ceiling behind a 90mm white polycarbonate bezel, requiring a 62mm diameter cut-out and 35mm recess depth above the ceiling surface.

The 5.8GHz microwave detection technology provides 360 coverage across a 3m diameter zone when installed at a standard 3m ceiling height, detecting motion through non-metallic materials such as plasterboard and lightweight partitions. This makes it suitable for triggering lighting in rooms where occupants may be partially screened from the sensor. The unit supports loads up to 1000W incandescent or 100W LED on 230V mains, with adjustable time delay (30 seconds to 30 minutes), lux threshold (5-1000 lux) and sensitivity range (1-3m).
