The Telemecanique XS218B4PBL2 is a tubular inductive proximity sensor — a non-contact device used to detect the presence of metallic targets on industrial automation lines. It sits in the sensor category alongside the rest of the Telemecanique XS2xx detection family. As an inductive proximity sensor, the XS218B4PBL2 generates an electromagnetic field at its active face and switches its output when a metal target enters that field — the standard no-contact alternative to a mechanical limit switch for cylinder-position, part-present, and end-of-travel sensing on conveyors, packaging cells, and machine tooling.
The listed lifecycle stage reads current, so the XS218B4PBL2 is in production and a normal factory-quote supply path applies. The commercial identifier on file is UPC 389119037221. No official replacement code is published alongside this listing.
