What it is and where it fits
The Schneider Electric (Telemecanique) XS8C1A1NBL2 is a flat-body inductive proximity sensor in the XS8 series, with a housing measuring 40 x 40 x 15 mm. The 15 mm dimension corresponds to the sensor's thickness – the key number for panel or bracket clearance. This class of sensor detects metal targets without contact and is used across packaging lines, conveyors, and machine tools where a low-profile mount is needed.
