Features MAIN PURPOSE: The magnetic rotate speed sensor can be used to work with a tachometer to measure the engine rotation speed. 2 OUTPUT TERMINAL: The sensor has two output terminals, and a shielded wire should be used to connect the output terminal of the sensor to the tachometer to ensure smoothly transmission. BRASS MATERIAL: The rotation speed sensor is made of excellent brass material, with high hardness, not easy to be damaged. STANDARD THREAD: The RPM speed sensor with standard M16x1.5 thread and simple structure is simple connect and install. IP44 PROTECTION: This generator speed transducer features IP44 protection grade, could adapt to most working environments. Specification: Item Type: Magnetic Rotate Speed Sensor Material: Brass Model: SL M16x1.5 Operating Environment Temperature: -30℃ to 120℃ Maximum Inductive Voltage: 50V AC Maximum Tightening Torsion: 49Nm Installation Thread: M16-1.5x60mm Output Signal: Switch Type Protection Grade: IP44 Linearity: 5 (%F.S.) Hysteresis: 5 (%F.S.) Repeatability: 0 (%F.S.) Sensitivity: 100% Feature: This product is a magnetoelectric speed sensor, which installed near the flywheel of the engine, when the engine rotates, the speed sensor senses an AC signal, and its frequency is proportional to the engine speed. The speed sensor and tachometer are used together to measure the engine speed. Package List:1 x Magnetic Rotate Speed Sensor Package List 1 x Magnetic Rotate Speed Sensor
