About This Safety Switch

This product is a safety interlock device from the Pilz PSENmech series, often referred to as a **safety gate switch** or **guard interlock**. Its primary function is to prevent access to machinery while hazardous operations are in progress. The switch employs the **spring force principle** for guard locking, meaning the guard remains locked by a mechanical spring and requires electrical power (24 V AC/DC) to disengage the lock. This design is inherently safe against power failure (fail-safe to locked). The switch features a reliable 2 N/O and 2 N/C safety contact configuration and uses spring-loaded terminals for robust and vibration-proof wiring.

Applications

This safety switch is crucial for interlocking and monitoring guards on various industrial machinery, including:

• Robotic Cells and Workstations
• Packaging and Palletizing Machinery
• CNC Machines and Machining Centers
• Protective Fences and Access Gates on Conveyors
• Any machinery requiring locked access during hazardous runtime
