Specification: Item Type: Punch Electronic Counter Material: ABS Battery Model: 1.5V AA battery(not included) Counting Range: 0-99999 Highest Frequency of Counting: 20HZ Counting Minimum Pulse Width: 1MS Clear Minimum Pulse Width: 1S Magnet Induction Proximity Distance: Approx. 10 ~ 15mm / 0.39 ~ 0.59in Magnetic Induction Distance: ≥ Approx. 35mm / 1.38in Package List: 1 x Counter 1 x Magnetic Control Induction Switch 1 x Magnet 1 x Bracket Note: 1. 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. 4. The use temperature of the magnet cannot exceed 70 degrees Celsius. If the temperature is too high, the magnetism will disappear and the induction will fail. 5. When the screen display is blurred, please replace the new battery; when not in use for a long time, please press to pause or switch the machine to turn off the counter and auxiliary battery; you can also take out the battery together to prevent the battery from deteriorating and leaking and damaging the counter.  Package List 1 x Counter 1 x Magnetic Control Induction Switch 1 x Magnet 1 x Bracket
