What this catalog line actually is
The Schneider Electric XCMD2103L1 is the Osiswitch miniature heavy-duty limit switch with a steel roller plunger head, a 1NO-1NC snap-action contact set, and a 1 m pre-wired removable cable exit — the form factor machine builders reach for when a sub-miniature body has to survive a real industrial envelope. Snap-action operation with 3.1 mm pretravel and 1.4 mm differential travel, driven by a 35 oz-inch operating force — the differential figure is the one that defines repeatability on a limit-stop fixture, and 1.4 mm on a steel-roller plunger is the band the rest of the XCMD family is sized against.
Ratings that decide the fit
Contact rating is 240 VAC at 1.5 A and 250 VDC at 0.1 A — the AC figure covers standard control-circuit switching (relays, contactors, PLC inputs) while the 0.1 A DC rating tells the buyer this is not a low-current logic-switch part; DC switching of inductive loads needs the arc-suppression hardware the rest of the circuit provides, not this contact alone.
Enclosure and where it physically lives
The enclosure rating is NEMA 1/2/4/4X/6/12/13 plus IP66, IP67, and IP68 — the NEMA 4X and IP67 pairing is the one most buyers actually specify against: corrosion-resistant outdoor duty and water-jet washdown on food-and-beverage or general process lines, with the IP68 figure covering temporary submersion where the cable gland is also sealed to the same standard. Operating temperature spans -13 to 158 °F, so the XCMD2103L1 sits comfortably inside an unheated cabinet in winter and on the warm side of an enclosure near a drive or motor without derating the mechanical life curve.
Standards, approvals, and traceability
The switch carries UL and CSA approval and is built to EN/IEC 60204-1 (machine electrical equipment) and EN/IEC 60947-5-1 (low-voltage switchgear control devices) — the 60947-5-1 citation is what lets a panel builder drop the XCMD2103L1 into an industrial control assembly without a separate exception in the declaration of conformity. UPC 78590126948 (12-digit 785901269489) is the traceability key on the carton and the datasheet; the Square D / Schneider brand and the Osiswitch series sit on the nameplate, so a PO line against the Schneider XCMD2103L1 cross-checks against the same OEM identity across either marking.
Lifecycle and the RFQ path
Quoting against the BOM is the way this part is bought: confirmed stock and current unit pricing come back against the RFQ, with the 1 m cable, roller plunger orientation, and 1NO-1NC contact set matched to the existing machine drawing before the PO is cut.
