The ABB 2TLA050204R0332 is a LineStrong3D pull wire emergency stop switch, built for long-run guarding on conveyors, transfer lines, and automated machinery where a single pull wire replaces multiple push-button e-stops. It covers spans up to 250 m, so one switch can protect a full conveyor or a long machine cell without daisy-chaining multiple units. The contacts are IEC/EN60947-5-1 double break Type Zb with silver contact material, giving positive-break confirmation for safety circuits. The die-cast painted yellow housing and IP67 rating mean it handles washdown environments and outdoor installation without a secondary enclosure.
Mounts with four M5 bolts through the base. The 9.2 cm x 36.1 cm x 14.3 cm footprint fits on machine frames or stand-off brackets. Four M20 x 1.5 conduit entries give flexibility for cable routing in any quadrant — useful when retrofitting into an existing panel gland plate.
