Motion detector MD-8 ECO - STEINEL

With the new motion and presence detectors of the Eco Plus series from STEINEL, the most common sensor-based standard requirements and everyday scenarios in the contract sector can be successfully and easily implemented. The pragmatic entry-level models form a sound basis for intelligent, energy-saving and environmentally friendly light management, taking into account the prevailing daylight. The high-performance infrared sensors convince with reliable 360° detection that can be adapted as required by means of plug-in cover caps in matching colours.
The MD-8 motion detector and the PD-8 presence detector from STEINEL, detect movements in a diameter of 8 m. While the MD-24 motion detector and the PD-24 presence detector even have a range of 24 metres. The two presence detectors (PD) are additionally equipped with a presence detection function that covers a presence range of 6 and 7.5 m respectively. All sensors of the Eco Plus series are available as flush-mounted, surface-mounted or ceiling-recessed versions.
