A hoist includes a cable deployment sensor to sense the length of a cable that is deployed from a cable drum (26) of the hoist. The cable deployment sensor includes a stationary ring (44) and a rotatable ring (46) disposed coaxially on the cable drum axis. A cluster assembly (48) is mounted to rotate about the cable drum axis simultaneously with the cable drum (26). The cluster assembly (48) includes a cluster gear (52) with a first gear (54) engaging the stationary ring (44) and a second gear (56) engaging the rotatable ring (46). The second gear (54) drives the rotatable ring (44) about the cable drum axis, and the rotatable ring (46) drives rotation of an input gear (60) for a sensor assembly (40).
