What the category tells a sourcing buyer
Classified as an inductive proximity sensor, the XS618B1PAL01C detects the presence of metal targets without physical contact — typical deployment is on a conveyor line, a machine guard door, or a part-present station where the sensor body mounts in an M18 threaded hole and the output switches a 24 VDC PLC input. The UPC 12-digit identifier 389119026881 ties this exact order code to the Telemecanique catalog; that same UPC appears on the unit packaging and is the number a storeroom scanner or ERP system uses to confirm the right part arrived against the PO.
