The Telemecanique XCMD4102T1 is a General/Heavy Duty Limit Switch, categorized for the rugged end of position sensing where a standard limit switch might not hold up. The sub-category tag tells you this unit is built for environments with higher mechanical stress or contamination risk — think conveyor transfer points, press guards, or machine tool door interlocks where the actuator sees repeated impact or washdown.
The UPC 12-digit barcode 389119079603 is printed on the retail packaging. For quality-doc traceability or PO matching, that number ties the physical unit to the Telemecanique order code without ambiguity.
