Pull-wire emergency stop for long hazard zones
The ABB 2TLA050202R0322 is a LineStrong2Z pull-wire emergency stop switch designed to guard extended access areas like conveyors, assembly lines, or automated machinery where a single push button cannot cover the full hazard zone. The stainless steel 316 enclosure (IP67/IP69K) means it withstands high-pressure washdown and corrosive environments — suitable for food-and-bev, pharmaceutical, or marine installations where hygiene and corrosion resistance are required.
Wire span and contact rating
Wire span reaches up to 100 m, so a single switch can cover a long conveyor or gantry line without daisy-chaining multiple units. The contacts are IEC/EN60947-5-1 double break Type Zb with silver contact material — a forced-opening design that ensures the normally closed contacts break even if welded, meeting the safety standard for emergency stop circuits. Three M20 conduit entries give flexibility for cable routing in tight panel layouts.
