A header height sensor (102) for an agricultural harvester has an elongate sensor arm (112), a reversing joint (114) and a rotary sensor (116) mounted to a bracket (106) that is fixed to a plastic point (100) of a harvesting head. The bracket is configured to be fixed to the plastic point (100), and is also configured to support an upper portion of the reversing joint (114) for relative rotational movement about a laterally extending longitudinal axis (196). The rotary position sensor (116) is coupled to bracket 106 and coupled to reversing joint (114) such that movement of the reversing joint (114) with respect to the rotary position sensor (116) causes an electrical signal from rotary position sensor (116) to change as a function of the relative rotation.
