STEINEL multi-lens technology
STEINEL multi-lenses are visually reminiscent of a fly's compound eye and therefore enable seamless monitoring of a hemispherical detection zone. It is thus the optimum lens system for motion detectors with dual or triple sensors with detection angles from 180° to 360°.
Fresnel lenses offer the simplest way to segment the detection range of an infrared detector. A group of individual lenses is arranged in a circular segment. With a maximum detection angle of 180°, an area of up to 225m2 can be reliably monitored. A second optical window for the area below the main detection zone makes creeping under the sensors almost impossible.
STEINEL sensors usually have a max. Range of 12m, which can be shortened if the direction of travel is radial (towards the sensor).
Elegant, powerful and intelligent
With the development of the mini sensor, STEINEL has taken a whole new approach to implementing PIR sensor systems. A cone-shaped segment mirror directs the surrounding IR radiation onto a state-of-the-art, extremely powerful IR sensor chip. This design not only allows the system to be kept exceptionally small, but also enables reliable detection of movement in the entire 360° radius.
The new operating concept
To enable fast, intuitive adaptability of the sensor electronics to individual user needs, the sensor module can be removed from the luminaire in its entirety, adjusted at rest, inserted again and securely locked in place. Once the settings are made, the luminaire switches itself on as soon as the sensor is removed. This is convenient at dusk or at night. All the important information is printed on the sensor module itself, so no instruction manual is needed.
