ONOSOKKIEngine speed sensorOM-1200/OM-1500Electromagnetic induction speed sensor. Used for gasoline engine speed measurement and EV/HEV motor speed measurement. The speed is measured by detecting the leakage magnetic lines induced on the magnetic rotating shaft of the electromagnetic ignition engine. As long as it is placed parallel to the ignition coil, the speed detection can be easily performed. When measuring the speed of EV/HEV motors, it can be set on the motor at a right angle to the motor shaft. It can be used in conjunction with our company's engine speed display (AR-7240B, CT-6700, HT-6200, SE-1620, FT-2500, FT-7200, GE-2500), etc. OM-1200 OM-1500 Measurement object 2-stroke and 4-stroke gasoline engines, motors for EV/HEV Detection method Electromagnetic induction method Applicable indicator AR-7240B Analog engine tachometer CT-6700 Digital engine tachometer FT-2500 High-function tachometer FT-7200 Handheld high-function tachometer GE-2500 Diesel engine tachometer HT-6200 External sensor type tachometer SE-1620 Gasoline engine tachometer Operating temperature range 0 to +80 °C -10 to +100 °C Cable length Order separately (MX-005, MX-010, etc.) 4.9 m Dimensionsφ16 × 54 mm (sensor unit)φ 16 × 80 mm (including cable)φ16 × 30 mm Weight Approx. 65 g Approx. 130 g (including cable) Optional accessories MX-005 Signal cable (5 m) MX-010 Signal cable (10 m) MX-015 Signal cable (15 m) MX-020 Signal cable (20 m) OM-0102 OM-1200 fixing part (with 3 tapes)
