Abstract: Magnet assemblies of electromechanical assemblies for elevator systems are described. The magnet assemblies include a magnet, at least one rail engagement block, and an encapsulating body encapsulating the magnet and the at least one rail engagement block, wherein the encapsulating body is formed from a non-magnetic material. A target extension is formed from the material of the encapsulating body and extends away from the magnet and the at least one rail engagement block. A proximity switch target is held within the target extension for detection by a proximity switch.
