Aspects of the present disclosure relate to obstruction detector assemblies, systems, and related methods for detecting obstructions along oil and gas equipment. In one implementation, an obstruction detector assembly includes a driver housing having an internal chamber and a plurality of fastener openings. The obstruction detector assembly includes a driver stem disposed at least partially in the internal chamber of the driver housing. The driver stem is movable partially out of the internal chamber of the driver housing. The obstruction detector assembly includes a driver head disposed outside of the driver housing and coupled to the driver stem. In one implementation, movement of the driver stem and the driver head is used to detect obstructions (such as a wireline) in a wellhead structure. In one implementation, movement of the driver stem and the driver head is used to detect obstructions (such as sand) in a valve.
