M18 Engine speed sensor. magnetic speed sensor M18 screw size copper material

this speed sensor is for all kinds Diesel generator set. but please make sure the screw size is correct. This product is a magnetic speed sensor, which is installed next to the engine’s flywheel, the engine rotation speed sensor senses the AC signal, proportional to its frequency and engine speed. Speed sensor and supporting the use of the tachometer to measure engine speed. This product has a simple structure, easy installation, stable quality, reliable performance. The main performance Ambient temperature: -30 ~ 120 degree Maximum sense voltage: 50V AC Mounting thread: M18-1.5 × 68mm Precautions 1 The products use a wrench to tighten the threaded engine, maximum tightening torque of 49N * m 2 proximity sensor nose to the top surface of the gear is 1mm 3 has two output terminals of the sensor, the sensor should be between the tachometer output and reliable connection with shielded cable to ensure smooth transmission.
