The ABB 2TLA050021R1300 is a compact safety switch from the MKEY1 series, classified under Specialized Switches and Safety Switches. This is the part a maintenance team reaches for when a guard-door interlock or safety-position switch needs a direct replacement on a machine safety circuit.
What the category tells you about deployment
Classified as a safety switch, this part is intended for use in safety-related control circuits — typically guarding access points, interlocking movable guards, or confirming position in a hazard zone. It's the kind of component a controls integrator maps into a safety relay chain or a configurable safety controller, not a general-purpose limit switch.
