4P5820 / 4P-5820 Speed Sensor for Caterpillar
RJT PARTS supplies aftermarket 4P5820 / 4P-5820 Speed Sensors for Caterpillar equipment. This magnetic speed sensor helps monitor rotational speed in selected engine and drivetrain applications. It offers a replacement option for equipment maintenance, repair workshops and aftermarket parts distributors.
Caterpillar identifies 4P-5820 as an aluminum low-output magnetic speed sensor. Unlike powered sensors, this passive sensor does not require an external electrical power supply. Instead, it generates an AC signal as the target passes the sensor. The signal voltage and frequency correspond to the target’s surface speed.
