The 2TLA050200R1130: Safety switches like this one mount on machine guards, doors, or hinged access panels. The LINESTRONG1 series is ABB's compact, non-contact interlock range — so this part is the receiver/actuator pair that detects when a guard is open and drops the safety chain. No separate actuator listed here; verify the mating actuator order code for your guard geometry.
Lifecycle status is current — ABB lists this as an active catalog number, not a phase-out. That means standard factory lead times apply, no last-time-buy deadline to watch.
