The Telemecanique Sensors XSDC407138 is a rectangular inductive proximity sensor rated for 48 VDC at 100 mA. It uses a screw terminal connection and belongs to the XS series of block-style sensors commonly found in machine position sensing and part detection on conveyor lines.
Cross-reference note
The XSDC607139 sibling runs the same 12–48 VDC supply and 100 mA load, but its output is NO only and the sensing distance is adjustable 30–60 mm — in contrast to the fixed rating on this unit. Check the output configuration and sensing range before substituting.
