The Hytronik HC009S-KD is a microwave motion sensor built for light fittings where space is tight, such as LED bulkheads, 2D lamps and LED tubes. It gives a 220-240V output signal with on/off and dimming function, and detects movement across a 1-16m area. The antenna detaches from the sensor body, so only the small antenna needs to sit on the outer surface of the fitting while the sensor body and driver stay hidden behind the panel.

Metal louvres on linear office lights block microwaves, which is a common problem for fittings with this kind of grille. The detachable antenna gets around this: clamp it onto a T5 or T8 tube on the outside of the fixture, and keep the sensor's main body behind the metal plate.

Key features of this microwave motion sensor light switch

• Output, 220-240V, with on/off and dimming function
• Detection area, 1-16m, adjustable
• Detachable antenna, clamps onto T5 and T8 tubes, separate from the sensor body
• Sensor principle, microwave motion detector, 5.8GHz +/- 75MHz
• IP rating, IP20

Applications

Suited to fittings where a full-size sensor won't fit inside the housing: LED bulkheads, 2D lamps and LED tubes, particularly in office lighting with metal louvred diffusers that would otherwise block microwave detection.
