Allen-Bradley 440G-A27143 Guardmaster Actuator

The Allen-Bradley Guardmaster 440G-A27143 is a fully flexible stainless steel actuator designed to engage Guardmaster TLS-GD2 interlock switches as part of a guarded access system. Rockwell’s official listing identifies 440G-A27143 as a Guardmaster accessory (440A) and specifies it as the replacement actuator for TLSZ guard locking switches, with the GD2 model described explicitly as a fully flexible actuator. Its GD2 compatibility enables engagement across multiple door orientations, ensuring reliable actuation of the TLS-GD2 interlock as the guard closes and supporting durable, long‑term interlock performance in Guardmaster safety installations.
