Telemecanique Sensors XCSB703 Key Safety Limit Switch

Product Description

The TELEMECANIQUE SENSORS XCSB703 is a metal key-operated safety limit switch designed for machine guarding and industrial safety interlock applications. It features a NO/2NC contact configuration, providing one normally open and two normally closed outputs to suit a range of safety circuit designs. The switch carries an IP67 ingress protection rating, making it suitable for environments exposed to dust, coolant, and wash-down conditions. Licensed electricians and industrial maintenance technicians install this switch as part of compliant machine safety systems. Its robust metal housing supports reliable operation in demanding factory and process environments.

The XCSB703 is used in industrial machinery applications where key-actuated safety interlocking is required to prevent access to hazardous zones during machine operation. Typical installations include guard doors, safety gates, and access panels on manufacturing equipment. The key actuator design ensures the switch can only be released by removing or inserting the matching key, supporting positive-mode safety operation. It suits both residential-scale automation and commercial or industrial machine tool environments where compliance with recognized safety standards is required.

Key Features

• NO/2NC contact configuration supports flexible safety circuit wiring
• Key-operated actuator provides positive-mode interlock control
• IP67 ingress protection rating resists dust ingress and temporary water immersion
• Metal housing for durability in industrial environments
• Compliant with multiple international safety and electrical standards including UL 508, EN/IEC 60947-5-1, EN 1088/ISO 14119, and RoHS
• Utilization categories AC-15 and DC-13 for compatibility with a range of control circuit loads

Compatibility

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

Installation Notes

Installation should be performed by a qualified electrician or industrial maintenance technician in accordance with NEC requirements and applicable machine safety standards. De-energize and lock out the machine control circuit before servicing or replacing the switch. Mount the switch securely so that the key actuator aligns correctly with the guard door or access panel to ensure reliable positive-mode operation. Verify contact configuration and utilization category compatibility with the target safety relay or control system before wiring.
