ABB 2TLA050200R1030 LINESTRONG1 is a Type Safety Switch from the Smile family. It carries 2NC/2NO contacts and an NPT thread, making it a direct-fit replacement for a line-down guard door or hinged interlock on a machine safety circuit.
The 2NC/2NO contact configuration fits standard safety monitoring relay inputs (dual-channel with feedback loop). NPT thread mates with US-standard conduit or cable gland — no adapter needed for North American panel builds.
