Lifetime 50000h


     ON/OFF      Daylight Sensor      Detection Area       Warranty 5 years        Hold time



With a super compact design, it's a very small size for ceiling light, downlight and tracking light.

With a protruding module, it will need to remove a very few light bead on the board to expose the module out of the metal board


Wiring Diagram:

Simple wiring way with four terminals: 

"N,L" connecting with power supply and "N,L'" connecting with LED driver.


Detection Coverage

Max. detection range will be 12m for ceiling mounted; Max. Detection range will be 10m for wall mounted.

Typically installation height 2.5-6M. This figure indicates the maximum distance at the highest mounting height with 100% sensitivity.


DIP Switch Settings


1 to set detection area. 
In this area,movement will be detected and able to trigger the sensor. 100% detection area is also known as the strong sensitvity.

2&3 to set Hold time
The period of light keeping 100% brightness after moving objects leave the detection area.
4 to set Daylight threshold
Definition of the ambient brightness; only when the ambient brightness is lower than the preset specific lux amount, the sensor will work; when it's preset as "disable",the sensor works everytime it detects motion regardless the ambient brightness.


Application demo

1. Automatically ON/OFF function
Light on when detect movement and off after people leave at night. Applications: Corridor, Staircase.


2. No daylight function

The daylight threshold is set to "Disable".
Light on when detect movement, After people leave, Light off after hold on time. Applications: Dim places such as Basement Parking, Underpass.


Installation Method

1. Microwave can penetrate walls or glass thinner than 20cm and attenuate if thicker than 20cm.
2. The driver voltage shall be stable and float within 10%.
3. Detection area will be affected by speed of motion, mounting height and movement volume
