MSA246S 99

24GHz radar presence sensor(ON/OFF version)

MSA246S 99 is a 24GHz radar sensor based on Merrytek patented orthogonal antenna. Its antenna has high gain and wide detection range. Combined with Merrytek’s unique software algorithm and FMCW modulation,it can accurately detect micro movements brought by human in almost all indoor spaces to automatically turn on or turn off lighting etc electrical appliance.

Product details

Product dimension

  • Dimension:φ63(Internal diameter)x80.5mm/φ80(external diameter)x80.5mm
  • Connection: 6-pin terminal

 

Initialization

When powered on,sensor indicator will turn off after flashing for 10S and will enter a 10S detection cycle,if there’s presence detected,then sensor will report presence and enter hold time calculating,if absence detected,then sensor will report absence.During initialization,sensor will not detect moving signal and you can use our MH10/MH18 remote or rotation switch to adjust detection area、hold time and daylight sensor etc parameter.

 

Factory setting

  • Detection Area: 4M
  • Hold Time: 30S
  • Indicator light :Open
  • Daylight sensor :Disable

Wiring suggestions

 

Wiring layout suggestion:

  1. LN terminal stands for AC input, L’N’ stands for AC output,please wiring correctly
  2. One sensor’s max loading capacity is 1200w resistive loading and 600w inductive loading for one single load.if you want connect more load in one loop,we recommend to add an AC contactor in our output LN terminalto avoid momentary surge overload.
