1. An electronic actuator for an elevator safety brake, comprising:
an electromagnet assembly; and
a first magnet assembly disposed forward of the electromagnet assembly and configured for being deployed to engage, and retracted from engagement with, a hoistway rail, depending on an energized state of the electromagnet assembly, and
a second magnet assembly disposed aft of the electromagnet assembly, wherein the first and second magnet assemblies are configured with a reverse polarity relative to each other;
wherein: the first magnet assembly includes: blocks spaced apart from each other in a transverse direction, respectively defining block bodies, and block legs respectively extending aft from the block bodies; and the first magnet is disposed transversely between the block bodies; and the second magnet assembly includes: further blocks spaced apart from each other in the transverse direction, respectively defining further block bodies, and further block legs respectively extending forward from the further block bodies; and the second magnet is disposed transversely between the further block bodies.
