Item Type: Punch Electronic Counter <br>Material: ABS <br>Battery Model: 1.5V AA battery(not included) <br>Counting Range: 0-99999 <br>Highest Frequency of Counting: 20HZ <br>Counting Minimum Pulse Width: 1MS <br>Clear Minimum Pulse Width: 1S <br>Magnet Induction Proximity Distance: Approx. 10 ~ 15mm / 0.39 ~ 0.59in <br>Magnetic Induction Distance: ≥ Approx. 35mm / 1.38in<br>1、ACCURATE AND CONVENIENT: This counter using magnet induction, simple and convenient installation, bring accurate counting <br>2、EASY BATTERY REPLACEMENT: Using ordinary AA batteries(not included), no external power supply is required, and the battery is easy to replace <br>3、SEISMIC PROOF AND STABLE: Adopt seismic proof design, effectively ensure the stable and reliable operation of the system <br>4、NO WEAR AND RELIABLE: No mechanical wear, support reliable operation and long service life, you can use with confidence <br>5、VARIOUS APPLICATION: 0?99999 5 digit digital display magnetic electronic counter is suitable for punch, machine tool, assembly line1. 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 +. <br>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. <br>3. The sensing distance is related to the magnetic size of the magnet. You can change the sensing distance by changing different magnets. <br>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. <br>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. <br>6. Use an ordinary AA battery, never connect an external power supply (external power supply will damage the counter); the power consumption of the counter is ultra low, so it is not necessary to press the pause or switch to turn off the counter every day to save power. <br>7. If the counter is abnormal, it can be restarted. Method: Take out the battery, install the battery in the opposite direction, then take out the battery, and then install the battery in the standard direction.<p>1 x Counter</p><p>1 x Magnetic Control Induction Switch</p><p>1 x Magnet</p><p>1 x Bracket</p>
