Using:
The magnet close to the magnetic proximity switch about 0.5-1 cm, then the magnet away from the magnetic proximity switch
for a certain distance (typically 3-5 cm or more). Then start counting.
Note:
1, the count signal and reset signal input switching should closer to the counter terminal.
2, to avoid unnecessary interference, if necessary, please use shielded cable, shield connected to the count terminal "+".
3, recommended to use magnetic switch
