Feature: 1. This product is a magnetoelectric speed sensor that can be installed next to the flywheel of the engine 2. When the engine is rotating, the speed sensor senses an alternating current signal, the frequency of which is proportional to the engine speed 3. The speed sensor and tachometer are used together to measure the engine speed 4. The product has simple structure and easy to install 5. Made of high quality, stable and reliable performance Specification: Item Type:Speed SensorWorking Environment Temperature: -30℃ ~ 120℃ Maximum Induced Voltage: 50V AC Installation Thread: M18 x 1.5 Detection Distance: 1mm Speed Range: 10KHZ . Package List: 1 x Sensor Note: 1. 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.
