Severe Duty rating — what it means on the line
The XCKN2545P20 carries a Severe Duty Limit Switches classification — that's the Square D / Telemecanique tier built for washdown, vibration, and debris-heavy environments where a standard limit switch would fail early. It's the switch you spec for conveyor transfer points, packaging lines, or outdoor material handling where the enclosure needs to keep grit out and the actuator needs to survive repeated impacts.
UPC and brand traceability
UPC 12 digit is 389110546685 — that ties the package barcode back to the Telemecanique XCKN2545P20 Limit Switch, branded under Square D Sensors & Safety. Useful for receiving verification and inventory scanning against the PO.
