In-Ceiling Motion Detectors

The KINASGARD® DBWF ⁄ DBWF-C motion and occupancy sensor detects the presence of stationary and moving people and has a switch contact output. It is used for surveillance, occupancy status detection and motion-depending control of room functions, such as for heating temperature reduction in non-occupied rooms.

Assured precision

The devices are tested according to the latest criteria. Each sensor is precisely re-adjustable using offset potentiometers. Take advantage of our experience, our development, manufacturing and product know-how and order your light and motion sensors directly from the manufacturer.


Broad spectrum

Our active motion and light intensity sensors are designed to be multifunctional. This reduces the diversity of types and expands their possible applications. Thanks to microprocessor technology, almost any measuring range can be represented, including customer specifications. DIP switches on our light and motion sensors allow you to set multi-zone switching.

How our light intensity and motion sensors benefit you:

  • Extremely robust and easy to install
  • Patented S+S design
  • Factory certificate for increased requirements
  • Digital photo sensor in our light and motion sensors
  • Diffuser with special transmission and absorption rates
  • Offset potentiometer
  • Quality assurance via bus system

How do our motion detectors work?

The light and motion sensor used in PHOTASGARD® brightness sensors has been specially adapted to eye sensitivity. It is most sensitive in the range of 400 nm to 700 nm. Therefore, with its special filter, the sensor is ideally suited for use in measuring the brightness of daylight and ⁄ or measuring artificial light of high colour temperature (similar to sunlight).
Nothing less than a high-end infra-red sensor with extended beam angle is used In all KINASGARD® motion sensors or presence detectors. The patented lens system with 20 individual lenses results in only very small dark areas that are just a few centimetres wide even at a distance of 10 m, thereby reliably detecting small movements. The sensor detects changes in infra-red radiation, i.e. thermal radiation resulting from movements of people or objects. Such movements generate a temporary change of the temperature gradient in the field. Due to the constant presence of body radiation (heat), this solution is ideally suitable for detecting people. The temperature difference between sensor and object must be > 5 K
