Abstract: A frictionless electronic safety actuator (100) for use in an elevator system, which includes at least one electromagnet (110), and a magnetic plate (120) attached to a connection arrangement (190). The connection arrangement (190) is configured to connect the magnetic plate (120; 220) to a linkage (80) that is actuatable so as to move a safety brake (24) into frictional engagement with an elevator guide rail (20). The at least one electromagnet (110) is operable to selectively produce a magnetic force which acts upon the magnetic plate (120) to displace the magnetic plate (120) and thereby move the connection arrangement (190) to actuate the linkage (80) without the magnetic plate (120) coming into frictional engagement with the elevator guide rail (20).

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.
