NOTES (W):
This device is used for the detection of persons in up to 10 meters distance. The temperature difference between persons to be detected and
ambience must be greater than 5 K. When motion is detected, the potential-free relay output switches. The hold time for the output, measured
from the time when last motion was detected, can be pre-set between 4 seconds and ca. 16 minutes. The sensor is characterized by its wide
reach while being small in size. The potential-free changeover contact is used for switching extra-low voltage only.
®
In all KINASGARD motion sensors and presence detectors, a high-end variant infrared sensor with enlarged angle of aperture is exclusively used.
Because of the patented lens system with 20 individual lenses, only very small dark areas are resulting, which even at a distance of 10 m are only a
few centimeters wide, safely detecting also small motions. The sensor recognizes changes in the infrared radiation spectrum, so in heat radiation,
resulting form the movement of persons or objects. Such movements generate a temporary change of the temperature gradient in the field. Because
of the always present body (heat) radiation, this sensor is excellently suitable for the detection of persons. The temperature difference between
sensor and object must be > 5 K.

Characteristic curve showing the sensor's
sensitivity in respect of the wavelength of light.
The broken line represents the light perception
of the human eye.
The sensor used in PHOTASGARD
was specifically adapted to the sensitivity of the human eye.
Its greatest sensitivity is in the range of 350 nm to 820 nm.
Therefore with its special filter the sensor is predestined for
exposure measure ment of daylight and ⁄ or for measuring
artificial light of high colour temperature (similar to sunlight).
