What the SENSE 9 is and where it lands
The ABB 2TLA050058R4100 is a SENSE 9 safety switch with a 2 m cable, 2NC/1NO contact configuration, and built-in LED indication. It's the kind of part you spec into a guarding circuit — interlock on a gate or a hinged door where you need positive-break NC contacts for the safety chain and a NO for the PLC status input. The LED gives a quick visual on contact state without needing a multimeter.
