J1939 Data Bus

A specialized data bus standard used in heavy-duty vehicles and industrial equipment to facilitate communication between the vehicle's components and external devices.

Inductive Pulse Generator

A shaft speed or position sensor that produces analog AC voltage signal by using a rotating reluctor wheel (aka chopper wheel, pulse wheel) that cuts through a permanent magnetic field; the computer that receives the signal measures the AC frequency and correlates it to rpm. The principle used in wheel speed, transmission tailshaft speed, crankshaft speed, and many other types of shaft speed sensors.

Rail Position Sensing

Technology used to detect the exact position of a train on the tracks, crucial for safety and efficiency.
