Knightsbridge Modular Microwave Sensor for LED Battens

The Knightsbridge modular microwave sensor is a plug-in occupancy detector designed to convert compatible LED battens into sensor-controlled fittings. The sensor uses microwave detection rather than passive infrared, allowing it to detect movement through non-metallic materials and offering greater sensitivity to minor motion. Detection area, hold time and lux threshold are all adjustable via rotary controls on the sensor body.

The sensor plugs directly into Knightsbridge MLA-compatible modular LED battens via a white connector cable, sitting inline between the mains supply and the LED driver. Once installed, the batten switches on when movement is detected and the ambient light level falls below the set lux threshold, then remains on for the configured hold time before switching off. This occupancy-based control suits storerooms, corridors, plant rooms, workshops and WCs where lights are frequently left on by accident.

The sensor body is a white polycarbonate enclosure measuring 61mm x 29mm x 26mm, light enough to be supported by the cable alone without additional fixing. The microwave detection range is adjustable from approximately 2m to 8m radius depending on the dial setting, allowing the sensor to be tuned to avoid false triggers from movement outside the room. Hold time adjusts from approximately 10 seconds to 12 minutes, and the lux threshold can be set to activate only in low light or to operate regardless of daylight.

Product Specification Sheet

Which Knightsbridge battens is this sensor compatible with?

The sensor works with Knightsbridge MLA-compatible modular LED battens, including the BATM single modular batten range. Check that your batten has the white plug-in connector before ordering. The sensor does not work with non-modular or non-MLA fittings.

How is the detection range adjusted?

The sensor has rotary dials on the body for detection area, hold time and lux threshold. Detection range adjusts from approximately 2m to 8m radius. These dials are accessible once the sensor is fitted, so settings can be changed without disconnecting the unit.

Does the sensor work in daylight?

The lux threshold dial allows the sensor to be set to activate only in low light (ignoring movement during daylight) or to operate regardless of ambient light level. This prevents the batten switching on unnecessarily in naturally-lit rooms during the day.

What's the difference between microwave and PIR sensors?

Microwave sensors detect movement through non-metallic materials (plasterboard, wood, plastic) and are more sensitive to minor motion than passive infrared sensors. This makes them better suited to small enclosed spaces where a PIR's line-of-sight requirement would be limiting, but they may also trigger more easily from movement outside the intended detection zone if not calibrated correctly.
