The OM-1500/1200 motor/gasoline engine RPM detector is designed for rotation measurement of a gasoline engine and an EV/HEV motor. It detects magnetic flux leakage from the motor itself or the engine’s ignition coil.

This easy to use and durable detector can measure engine rotation by attaching in parallel with the ignition coil. When the EV/HEV motor rotation is measured, attach the OM-1500/1200 perpendicular to the motor rotating shaft.

It is used with the engine tachometer by Ono Sokki (GE-2500, AR-7240B, CT-6520B, HT-6200, SE-1620, FT-2500, FT-7200).
