SL-MW-DA µDim Microwave DALI Sensor
The SL-MW-DA miniature microwave presence detector provides
automatic control of lighting loads. The unit comes complete
with a flush-mount bracket, allowing unobtrusive mounting of
the sensor head into ceiling tiles or onto solid surfaces. It has
been designed so that it can be used for luminaire mounted or
ceiling mounted applications. As microwave radiation penetrates
plastic and glass, this unit has been specifically designed to be
mounted inside a luminaire.
The product consists of the following :
• Sensor head with integral RJ11 sensor lead
• Power supply unit
• Flush mount bracket
Presence detection: when movement is detected the load will
automatically turn on; when the area is no longer occupied the
load will automatically switch off after an adjustable time period.
