Telemecanique Sensors XCSPA591 Key Safety Limit Switch

Product Description

The TELEMECANIQUE SENSORS XCSPA591 is a key-operated safety limit switch designed for machine guarding and industrial safety interlock applications. It features a 2NO/2NC contact configuration, meaning two normally open and two normally closed contacts operate simultaneously when the key actuator is inserted or removed. The switch body is rated IP67 for dust-tight and temporary immersion protection, making it suitable for harsh industrial environments. Licensed electricians and industrial maintenance technicians install this switch as part of machine safety circuits compliant with EN/IEC 60204-1 and related standards. The key actuator is sold separately under part number 69532950.

This switch is used in industrial machine guarding systems where positive-mode safety interlocking is required. It is well suited for guarded enclosures, access doors, and safety gates on manufacturing equipment. The 2NO/2NC contact arrangement supports dual-channel safety relay and safety PLC wiring schemes common in Category 3 and Category 4 safety architectures. It is appropriate for both light-duty and heavy-duty machine installations where a coded or non-coded plastic key actuator controls access monitoring. The switch body mounts in a compact footprint, fitting tight panel and door-frame installations.

Compatibility

Designed for use with a compatible plastic key actuator sold separately under part number 69532950. Consult the manufacturer wiring diagram and safety relay documentation to confirm contact ratings and channel configuration before installation.

Installation Notes

Installation should be performed by a qualified electrician or industrial maintenance technician familiar with machine safety standards including EN/IEC 60204-1 and NFPA 79. De-energize and lock out the machine before mounting or wiring the switch. Confirm that the safety relay or safety PLC connected to this switch is rated to accept a 2NO/2NC input channel configuration. Do not defeat or bypass the interlock circuit during testing — use the appropriate bypass function on the connected safety controller if required by the maintenance procedure.
