Sensotec System 55, with remote control, matt black. The detection uses the Doppler effect, similar to speed measurement in road traffic. Detection can also be carried out through non-shielding materials. For example, toilet facilities could be covered with a single Sensotec. Features: - Contactless switching prevents dirt. Contamination by viruses and bacteria from the user is therefore excluded. - Detection in the near and far range depends on the reflection surface, the speed and type of object (person, animal, object, etc.). - Metal frames influence the detection range. - Extensions to the detection range. - Extension operation with rocker switch. - Requires an IR remote control to start up and set various functions. - Individual brightness value and follow-up time possible (teach function). - Sensitivity of the remote detection is adjustable. - Installation in a deep device box. - Meets the requirements of the VDI6008 Sheet 3 guideline. - The Sensotec is an active motion detector. It detects movements in the detection area regardless of temperature and switches the room lighting on at a dimmed level depending on the ambient brightness. - Movement in the near area switches the room lighting on undimmed. - The brightness of the room lighting can be adjusted when it is detected remotely. Notes: - An IR remote control is required for commissioning and to set various functions.
