Product details

Dimension

  • Product size: φ52.5x34mm
  • Connection interface: 4-pin terminal

 

Initialization

When powered on,sensor indicator will turn off after flashing for 20S and will not detect moving signal during this time. After 20S,you can use our MH10 remote or dip switch to adjust detection area、hold time and daylight sensor etc parameter.

 

Factory setting

Detection Area: 100%,  Hold Time: 5S, Daylight Sensor:Disable

Wiring suggestions

 

  • LN terminal stands for AC input, L’N’ stands for AC output,please wiring correctly
  • One sensor’s max loading capacity is 800w resistive loading and 400w 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 terminal to avoid momentary surge overload.
