Engineered for Reliable Safety Monitoring
Safety switches such as the FR3393 are designed to monitor guard doors, gates and moving machine components. When the actuator is removed or disengaged, the switch interrupts the safety circuit, ensuring immediate shutdown of hazardous machine movement to protect personnel and equipment.
The 1 NO + 1 NC configuration provides both safety interruption and auxiliary signalling, allowing seamless integration into industrial control and automation systems.
Typical Applications
- Machine guarding and safety interlock systems.
- Access control for industrial enclosures and safety doors.
- Packaging and automated production lines.
- Conveyor and material handling systems.
- Industrial machinery safety monitoring.
- Automation systems requiring reliable safety feedback.
