TECHNICAL DATA
Motion Detector – BWM
1.8 Function
The motion detector is used to detect the movement of persons at a distance of up to
10 m. The sensor detects movements with an opening angle of 110° and 360° sco-
pe. The lens system with 20 individual lenses results in very small dark areas, which
are only a few centimetres in size at a distance of 10 m and safely detect smaller
movements.
The temperature difference between the person to be detected and the environment
must be greater than 5 K. The sensor detects changes in the infrared radiation (ther-
mal radiation) resulting from the movement of persons or objects. These generate a
temporal change in the temperature gradients in the field. If a movement is detected,
the potential-free relay output is switched. The hold time for the output, measured from
the time of the last detected movement, can be set from 4 seconds to around 16 minu-
tes via potentiometer. The potential-free changeover contact is only used for switching
safety extra-low voltages.
