Telemecanique Sensors XCSE7511 Key Safety Limit Switch

Product Description

The TELEMECANIQUE SENSORS XCSE7511 is a metal key-operated safety limit switch designed for machine guarding and access control applications in industrial environments. It features a NO/2NC contact configuration and operates at 24/48 VAC/VDC across multiple amperage levels. The IP67 ingress protection rating makes it suitable for wash-down and dusty conditions. Electrical and mechanical safety engineers install this switch as part of safety interlock circuits on guards, gates, and access panels where personnel protection is required. The key actuator design helps prevent simple defeat of the safety function.

The XCSE7511 is suited for use in light industrial and heavy manufacturing settings where guard door monitoring is required. It integrates into safety relay or safety PLC circuits as a guard door interlock, door position monitor, or access-gate safety switch. The switch is built to withstand typical factory floor conditions including exposure to coolants, dust, and vibration. Applications include CNC machinery guards, press safety doors, conveyor access panels, and similar machine safety perimeter installations.

Key Features

• NO/2NC contact configuration supports redundant safety circuit architectures
• Key actuator design resists unintentional or simple mechanical defeat
• IP67 ingress protection rating for dust-tight and temporary submersion resistance
• Operates at 24/48 VAC/VDC for compatibility with low-voltage safety control circuits
• Metal housing provides durability in industrial environments
• Compliant with multiple safety and electrical standards including EN/IEC 60947-5-1, EN 1088/ISO 14119, UL 508, and CSA C22.2 No. 14

Compatibility

Designed as an OEM-style safety interlock switch for industrial machine guarding applications requiring a key-operated limit switch with NO/2NC contact configuration and IP67 protection.

Installation Notes

Installation of safety limit switches must be performed by qualified electrical or mechanical safety personnel following applicable standards including EN/IEC 60204-1 and NFPA 79. De-energize and lockout/tagout all affected machinery before mounting or wiring the switch. Verify that the key actuator alignment and engagement depth meet the requirements of the guarded machine before commissioning. Post-installation functional testing of the complete safety interlock circuit is required before returning the machine to service.
