DIGITAL COUNTER: 5-unit tally counter, metal magnetic control induction switch , accurate and counting, no mechanical wear, work and long life.DIGITAL COUNTERS TALLY COUNTER: 5-digit large-screen LCD display, counting range of 0-99999; anti-vibration design, effectively preventing data loss, counting can be reset and paused.MAGNETIC INDUCTION SENSOR: metal magnetic induction counting, the opening diameter is 12mm; the induction distance is 10-15mm. The highest counting frequency: 20Hz; the smallest counting pulse width: 1mS.PANEL SIZE: counter external

size 64*38*38mm; counter opening

size 61*36mm, compact and easy to install.NOTE: The magnet sheet is used on the object to be detected, which is convenient for the detection of the magnetic sensor and thus the speed measurement. The magnetism disappears after 70°C, pay attention to the rotor temperature.
