2)MSP6729 MPU Magnetic Pickup Generator Speed Sensor Rotational Speed Sensor

Description:

The MSP6729 MPU Magnetic Pickup Generator Speed Sensor is used in engine and generator control systems to detect rotational speed by sensing the passing teeth of a flywheel or ring gear. Commonly installed in diesel generators, industrial engines, compressors, pumps, and power generation equipment requiring accurate RPM feedback for electronic governors and overspeed protection systems. Maintenance teams and system integrators use this sensor for generator repairs, governor upgrades, and replacement of failed speed sensing devices in industrial and standby power applications. The sensor generates an AC frequency signal proportional to engine speed without requiring an external power supply.

Applications:

The MSP6729 magnetic pickup speed sensor is commonly used in diesel generator sets, industrial engines, marine propulsion systems, irrigation pumps, compressors, and electronic governor systems where accurate engine speed feedback is required. The MSP6729 sensor is compatible with electronic speed controllers from GAC and similar governor systems used in standby and prime power applications.
