3785190 - Parker speed and direction sensor

Parker motor inductive speed and direction sensor (dual channel)

The Parker 3785190 is a dual-channel ferrostat differential sensor that measures both rotational speed and direction. The sensor installs in a threaded hole in the F12, V12 and V14 bearing housing and in the F11 barrel housing. The output is two phase-shifted square waves over a frequency range of 0 Hz to 15 kHz.
