It uses a 2NO\/NC contact configuration activated by a removable metal key actuator, providing positive-mode operation that meets modern safety circuit requirements. The switch carries an IP67 ingress protection rating, making it suitable for wash-down and high-contamination environments. Licensed electricians and industrial maintenance technicians install this switch as part of machine safety systems compliant with EN\/IEC 60204-1 and related standards. It is RoHS compliant and certified under UL 508, CSA C22.2 No. 14, and EN\/IEC 60947-5-1.\u003c\/p\u003e\n\u003cp\u003eThe XCSA503 is used in industrial machinery safety interlocks where guard doors, access panels, or safety gates must be monitored. It is suited for both Utilization Category AC-15 and DC-13 circuits, covering a range of control voltage applications. Typical installations include manufacturing equipment, packaging lines, conveyor systems, and other machinery requiring positive safety interlock confirmation before operation. The key actuator design deters casual bypass and is consistent with requirements under EN 1088\/ISO 14119 for interlocking devices associated with guards.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e2NO\/NC contact configuration for positive-mode safety interlock circuits\u003c\/li\u003e\n  \u003cli\u003eKey actuator type per EN 1088\/ISO 14119 — resists simple defeat or bypass\u003c\/li\u003e\n  \u003cli\u003eIP67 ingress protection rating — sealed against dust and temporary water immersion\u003c\/li\u003e\n  \u003cli\u003eRated for both AC-15 and DC-13 utilization categories\u003c\/li\u003e\n  \u003cli\u003eMetal housing construction for durability in industrial settings\u003c\/li\u003e\n  \u003cli\u003eMulti-standard certified: UL 508, CSA C22.2 No. 14, EN\/IEC 60947-5-1, EN\/IEC 60204-1, EN\/ISO 12100, RoHS\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style safety limit switch for industrial machine guarding and interlock systems requiring a key-operated actuator with a 2NO\/NC contact block in a compact metal housing.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a qualified electrician or industrial controls technician in accordance with NEC and applicable local electrical codes. De-energize and lock out the machine control circuit before mounting or wiring this switch. Verify that the key actuator engages and releases cleanly with the guard or door mechanism before returning the machine to service. Do not defeat or bypass the interlock circuit during testing.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eContact Configuration\u003c\/strong\u003e: 2NO\/NC\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eActuator Type\u003c\/strong\u003e: Metal Key\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSwitch Type\u003c\/strong\u003e: Key Operated General Safety Switch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eIngress Protection Rating\u003c\/strong\u003e: IP67\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUtilization Category\u003c\/strong\u003e: AC-15, DC-13\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Width\u003c\/strong\u003e: 1.57 inches (40 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Depth\u003c\/strong\u003e: 1.73 inches (44 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Height\u003c\/strong\u003e: 4.49 inches (114 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 1.13 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: UL 508, CSA C22.2 No. 14, EN 1088\/ISO 14119, EN\/IEC 60204-1, EN\/IEC 60947-5-1, EN\/ISO 12100, RoHS Compliant\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: TELEMECANIQUE SENSORS\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: XCSA503\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SCHNEIDER ELECTRIC","offers":[{"title":"Default Title","offer_id":51694608908594,"sku":"XCSA503","price":224.33,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/4ead50a6ad152e0fb80f556ad7c81a81.jpg?v=1788326202","url":"https:\/\/voomisupply.com\/products\/telemecanique-sensors-xcsa503-key-safety-limit-switch","provider":"Voomi Supply","version":"1.0","type":"link"}
