Product details

Product dimension

Dimension: φ85×52.5mm
Connection: 4-pin terminal

Initialization

When powered on,sensor indicator will turn off after flashing for 10S and will enter a 20S 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 remote or DIP 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

Detection Signal

The product detects human moving, minor moving, and presence signals, and realizes the detection of human-existing/no-human in non-sleep state. The following is a description of the moving, minor moving and presence signals:

Majormovement: detect the human significant moving (walking) in the detection area.
Minor movement: detect the human slight moving in the detection area, such as leaning forward, leaning forwarder and back, swinging limbs, shaking head, typing, playing with mobile phones and so on.
Micro movement: detect human abdominal and thoracic expansion behaviors caused by breathing, but not detect moving signal and minor moving signal.

Wiring suggestions

Wiring layout suggestion：

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 terminalto avoid momentary surge overload.
