A hoist includes a cable deployment sensor to sense the length of a cable that is deployed from a cable drum of the hoist. The cable deployment sensor includes a stationary ring and a rotatable ring disposed coaxially on the cable drum axis. A cluster assembly is mounted to rotate about the cable drum axis simultaneously with the cable drum. The cluster assembly includes a cluster gear with a first gear engaging the stationary ring and a second gear engaging the rotatable ring. The second gear drives the rotatable ring about the cable drum axis, and the rotatable ring drives rotation of an input gear for a sensor assembly.
