The ABB 2TLA050200R0030 is a LineStrong1 pull-wire emergency stop switch designed for guarding long conveyor lines, transfer stations, or any hazard zone where a rope-pull trip is the most practical way to stop equipment from multiple access points. The die-cast painted yellow enclosure carries an IP67 rating, so it handles washdown environments and outdoor installations without additional sealing.
Wire span up to 50 m means a single switch can protect a run of that length — common for conveyor belts, transfer decks, or gantry travel paths. The IEC/EN60947-5-1 double break Type Zb contacts with silver contact material give you a positively driven normally closed circuit that opens on wire pull or break, which is the standard safety architecture for emergency stop circuits. Three M20 x 1.5 conduit entries provide gland flexibility for incoming and outgoing cables without needing an extra junction box.
