Description: Five-digit big LCD, super low power consumption, large and clear indication Press Counting/Pause key (Pause) to stop counting, after 0-30 sec, LCD indication will be automatically off and in standby state. Press the Counting/Pause key again to turn on the indication and continue to count. Use magnetic induction, easy to install and precise counting. Maximum counting speed: 20 times per second Reset: through pressing the Reset buttons on board or exterior. Use the common 5th battery, free from external power supply Anti-vibration, efficiently ensure the stable and reliable system operation. Free from mechanical abrasion, safe work, long lifespan Specification: Power: 1.5V—AA 5th battery Reset modes: board/exterior Counting range: 0---99999 Available ambient temperature: -5-40°C Minimum counting PW: 10mS Dimension: 64*38*38*mm Distance within the magnetic induction: about 5-10 mm Distance out of the magnetic induction: ≥ 30mm Hole size: 61*36 mm Total weight: about 100g Configuration List: One digital counter, one magnet, one magnetic induction switch, one pair of supporters Package Includes: 1 Piece Digital Electronic Counter Punch Magnetic Induction Proximity Switch Note: Precautions and Special Introductions: 1.The signal lines of counting and reset should be as short as possible. Do not lay the signal line with strong current line or power line to avoid unnecessary interference; use the shielded line if necessary, which should be connected with the reset terminal. 2.The counting signal and reset signal only can be inputted with contact signal, other power signals are not allowed. 3.The induction distance is related with magnetism of magnet, so the induction distance can be adjusted by changing the magnet. 4.The operation temperature of magnet should be within 70 degree, over high temperature will cause magnetism lose, further to invalidate induction. 5.When the LCD indication is dim, please change the battery; if the device will be shutdown for a long time, please press the Pause key to close LCD and auxiliary battery; or take out the battery to prevent counter damage from leaked battery fluid. 6.The power consumption is very low, so no need to save power through pressing Pause key to close the LCD indication.
