The signal line for counting and clearing input should be as short as possible to avoid wiring with strong electricity or power lines to avoid unnecessary interference; if necessary, please use shielded lines, and the shielding layer is connected to the counting terminal +.2. Only the contact signal without voltage can be input for the counting signal and the reset signal, and no other electrical signals can be input.3. The sensing distance is related to the magnetic size of the magnet. You can change the sensing distance by changing different magnets.Package List1 x Counter1 x Magnetic Control Induction Switch1 x Magnet1 x Bracket
