DC-SSR Microwave Module Microwave Sensor Switch Radar Switch Module Body Induction Switch
Parameter:
1.Model:XZG-LDK-6
2.Input Voltage:3.7-12V
3.Output Voltage:3.7-12V
4.Maximum Load Current:3A
5.Maximum Load Power:30W (driving LED should less than 20W)
6.Sensing Distance:5m (customizable, the longest distance is 10m)
7.Delay Time:default 10 seconds (customizable)
8.Accessible to install photoresistance (need to customize,default no photoresistance)
Notice:
1.Don't operate during the power on;don't connect the wrong wire;don't
overload and short circuit;please read the instruction carefully before
using
2.Don't use it to overload power
3.When the wall thickness is smaller than 10cm,this switch may sensor throughout the wall
4.Don;t put any objects that may affect its detection or keep on moving
5.Don't take shakable object as install basement
6.Short-distance microwave signal and other superstrong magnetic
radiation source may influence the normal operation og radar switch
7.Owing to the difference of sensoring distance,the matching antenna model may be different when customization
