clamping example
*The real color of the IP-3100 is black.

The IP-3100 enables ignition pulse detection of gasoline engines with high sensitivity. The rotation speed can be easily measured by clamping the primary side cord (low voltage), the secondary side cord (high voltage), and current cable of the electronic distributor. The IP-3100 is used with the tachometer made by Ono Sokki.


  • Increasing the sensitivity enables to use for gasoline engines which was difficult to detect.
  • Also can clamp to the secondary side cord (high voltage) by improvement of opening section.
    (The cable up to φ10 mm can be clamped.)
  • Easy to handle the cable by changing cable material
  • Easy to use with one-touch clamping
  • High reliability with the heat-resistant structure (+120 °C)
