The Telemecanique XCKN2102P20 is a limit switch in the Severe Duty category, built under the Square D Sensors & Safety brand. This classification means the switch is designed for environments with heavy mechanical stress, contaminants, and repeated actuation — the kind of duty you see on conveyor transfer points, press brakes, or automated guided vehicle bumpers where a standard limit switch would wear out prematurely.
The XCKN2102P20 ships as a complete limit switch assembly — the head, body, and actuating mechanism are one unit. No separate mounting bracket or actuator head to order alongside it. The UPC 12-digit code (389110214263) on the package matches the order code for receiving verification against the PO.
