Schneider Electric XCS-Z03 Key-Tongue Actuator

The Schneider Electric XCS-Z03 Key-Tongue Actuator is a flexible pivoting actuator that mechanically engages Telemecanique safety interlock switches on hinged or sliding guard doors. It’s used throughout industrial automation—machine enclosures, packaging machines, robotic cells, and automated production lines—where guard-door interlocking protects operators and equipment. As part of the Telemecanique Safety Switches XCS family, this accessory (Manufacturer Part Number XCSZ03) is a pivoting key-tongue actuator designed for metal safety switches and compatible with XCSA, XCSB, XCSC, XCSE, XCSLE, and XCSLF devices. It serves as a mounting and fixing accessory with a compact form factor and a net weight of 0.095 kg, providing actuation when a guard door or protective gate is closed. The pivoting key-tongue design accommodates various guard configurations, and its action ensures engagement with the corresponding safety interlock switches when doors are closed. Common replacements include XCSZ01, XCSZ05, and XCSZ13. Typical users—maintenance teams, OEMs, and system integrators—employ it for repair, retrofit, or new equipment integration in automated manufacturing systems and machine tools.
