RJM4929C / RJM4920 · Crankshaft / Transmission Speed Sensor
For crankshaft and transmission speed measurement, Pin-to-pin compatible with mainstream devices for direct replacement, delivering highly reliable speed signals to the powertrain.
Package outline
RJM4929C measures crankshaft speed and RJM4920 targets transmission speed sensing. Both use a back-bias differential Hall architecture and output a digital signal proportional to rotational speed, providing the reference for fuel injection and ignition timing as well as transmission shift control.
Supplied in SIP-3 packages and pin-compatible with mainstream devices for direct replacement, they can be dropped into an existing design.
