Medium duty — what it means on a line
Classified as a Medium Duty Limit Switch, this XCKP2128M12 sits between light-duty precision switches and heavy-duty foundry-grade units. In practice, medium duty means the mechanical life and actuation force are spec'd for moderate-cycle applications — conveyors, packaging lines, material handling gates — where the switch sees thousands of cycles per shift but not the constant hammering of a stamping press. The part is a Telemecanique XCKP2128M12 from the Square D Sensors & Safety line, carrying the Schneider Electric brand. That means the nameplate, the replacement catalog, and the cross-reference all live in the Schneider/Telemecanique ecosystem — no orphan part number.
