Item Type: Punch Electronic Counter <br>Material: ABS <br>Battery Model: 1.5V AA battery (not included) <br>Counting Range: 0-99999 <br>Count Maximum Frequency: 20HZ <br>Counting Minimum Pulse Width: 1MS <br>Clear Minimum Pulse Width: 1S <br>Magnet Induction Proximity Distance: Approx.10-15mm/0.4-0.6in <br>Magnetic Induction Connection Distance: Approx.≥35mm/1.4in<br>1、Magnet Induction: The counter adopts magnet induction, which is simple and convenient to install, can count accurately <br>2、AA Battery: The counter uses ordinary AA battery, no external power supply is required, and the battery is easy to replace, battery not included <br>3、Anti Shock Design: The counter is designed for shock resistant, which can effectively ensure the stable and reliable operation of the system <br>4、Stable and Reliable: The counter has no mechanical wear, can stable and reliable to operate, has long service life <br>5、Widely Application: This counter can be used in punching equipment, printing and textile machines, assembly lines, auto repair equipment, etc.1. The signal line for counting and clearing input should be as short as possible, avoid wiring with strong electricity or power lines cause unnecessary interference, if necessary, please use shielded lines, the shielding layer connect to the counting terminal +. <br>2. The counting signal and clearing signal can only input the contact signal without voltage, other electrical signal can not 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℃, if the temperature is too high, the magnetism will disappear and the induction will fail. <br>5. When the screen display is blurry, please replace the battery with a new one. <br>6. When not in use for a long time, please press the pause/power key to turn off the counter and auxiliary battery, can take out the battery together to prevent the counter from deteriorating and leaking. <br>7. Use an ordinary AA battery, never connect an external power supply, the external power supply will damage the counter, when the power consumption of the counter is extremely low, you don't have to press the pause/power key to turn off the counter every day to save power. <br>8. If the counter is abnormal, you can restart the machine. 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 Punch Electronic Counter</p><p>1 x Magnetic Induction Switch</p><p>1 x Magnet</p><p>1 x Bracket</p>
