The Speed sensor MSP677 detects when ring gear teeth, or other ferrous projections, pass the tip of the sensor. Electrical impulses are produced by the sensor’s internal coil and sent to the speed control unit. The signal from the MSP677 Speed sensor MPU, teeth per second (Hz.), is directly proportional to engine speed. Speed sensors are available in various lengths in both U.S. and metric threads. Wire leads, military connectors, automotive connectors, or stud terminals are also available.
