Proximity sensors

Proximity sensors or microwave sensors (HF = High Frequency) use the Doppler effect by detecting movements extremely effectively. Microwave sensors work regardless of climate and through non-metallic materials such as plastics, glass, plaster and wood.

The sensors can be built into new luminaires and can also supplement existing lighting systems. The latter are built into the ceiling or into a special enclosure.   Microwave sensors are mainly used to control lighting but can also be used in other connections where you want to detect motion, e.g. for ventilation or surveillance.  The sensors are triggered by motion and then switch on the light or equipment, which is then switched off after a preset time interval. The sensors can have a built-in daylight sensor with adjustable light sensitivity.


A budget variant of on/off control for lighting or equipment. The HC008S has a built-in daylight sensor and adjustable sensitivity for microwaves.


The HC009S is like the HC008S, i.e. an on/off control for lighting or equipment, but with more advanced software. With the HC009S several sensors can be connected to the same luminaire, referred to as master to master, and can be used in long corridors, for example. The HC009X also has an automatic 100 hour burn-in function for new fluorescent tube luminaires.


The HC002S has the same software as the HC009S, i.e. with master to master function and automatic burn-in function. The HC002S is suitable for retrofitting and flush mounting in ceilings.
