30mm sensing Distance
suitable for most non-metallic material
Important note :
After connecting the wire, the LED light is always on and the switch cannot be controlled.
The reasons are as follows:
1. The Positive and negative electrodes are connected to the revese;
2. The input and output are connected inversely;
3.The working voltage does not match;

Solution:
1. first determine whether the driving power supply is 12V/24V
and whether the working voltage of the LED lamp is 12V/24V
2. check whether the positive and negative electrodes are connected in reverse. if the positive and negative electrodes are connected in reverse,
3.check whether the input and output are connected to the reverse to the long line is connected to the power supply, and the short line is connected to the LED light.
