Autometer Magnetic RPM Sensor 3/8in -24 X 0.625 in. (Includes 2 Magnets)

This AutoMeter magnetic RPM sensor kit comes with the sensor itself and two magnets. It's designed to pick up engine RPM signals, typically by counting rotations of a spinning component like a crankshaft or driveshaft, and sending that information to a compatible gauge or data acquisition system. The sensor features a 3/8"-24 thread size and a 0.625" sensing depth, making it a solid option for many custom setups.

The magnetic pickup design is a well-known method for accurately reading engine speed. The included magnets are what the sensor detects as they pass by, and the rate of detection translates directly into RPM. This setup is often used in applications where a direct tachometer signal isn't readily available or when building a custom dashboard for a project vehicle. AutoMeter is a popular name in gauges, and this sensor is part of their Stack Data Acquisition Series, suggesting it's built to integrate with other components in that line.
