The Telemecanique XCKP2111P16 is a Medium Duty Limit Switch from Square D Sensors & Safety, carrying a current lifecycle stage. This is the part you spec into a BOM line for position sensing on conveyors, transfer lines, or machine guards where the switch sees moderate mechanical cycling and needs a reliable snap-action contact block.
Rated for medium duty, this limit switch handles the typical load of a control-circuit signal — think pilot duty on a contactor coil or a PLC input — without the overbuilt actuator of a heavy-duty foundry switch. The "medium" rating means the mechanical endurance and contact ratings are sized for general machine-tool and packaging-line applications, not for continuous high-inrush or high-vibration zones near a press or shear.
The manufacturer brand is Square D Sensors & Safety, which places this under the Schneider Electric umbrella. The Telemecanique naming on the product description confirms it is part of the legacy XCKP series — a widely used global footprint for limit switches in industrial control panels.
