1This product is a magnetoelectric speed sensor that can be installed next to the flywheel of the engine 2When the engine is rotating, the speed sensor senses an alternating current signal, the frequency of which is proportional to the engine speed 3The speed sensor and tachometer are used together to measure the engine speed 4The product has simple structure and easy to install 5Made of high quality, stable and reliable performanceItem Type:Speed SensorWorking Environment Temperature: -30 ~ 120 Maximum Induced Voltage: 50V AC Installation Thread: M18 x 1.5 Detection Distance: 1mm Speed Range: 10KHZ1 x Sensor1. This product is tightened on the engine by a screw with a wrench, the maximum tightening torsion is 49N * m2.The distance from the end surface of the sensor to the top surface of the induction gear is 1mm3. The sensor has two output terminals, and the sensor output terminal and the tachometer should be reliably connected with shielded wires to ensure smooth transmission.
