196-1185 / 122-8862 / 318-1179 Magnetic Speed Sensors for Caterpillar

Product Overview

Looking for a magnetic speed sensor for Caterpillar equipment? RJT PARTS supplies aftermarket sensors for parts distributors, wholesalers, and machinery repair businesses.

Magnetic speed sensors detect the movement of a rotating target and convert it into an electrical signal. The signal helps the machine monitor rotational speed and position. Depending on the application, the sensor may work with an engine camshaft or a transmission output.

The part numbers 196-1185, 122-8862, and 318-1179 are listed as Cat magnetic speed sensors. However, they have different thread sizes and other specifications, so buyers should not treat them as direct replacements for one another.

Before ordering, check the original part number, thread size, connector, and equipment model. If you are unsure which sensor you need, send RJT PARTS the part number or a photo of your original sensor.
