Engineered for Reliable Safety Monitoring
Safety switches such as the FR2293-E3K21 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 2 NO + 1 NC configuration enables both safety interruption and auxiliary signalling, making it suitable for integration into modern automation systems where monitoring, redundancy and control feedback are required.
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 requiring signalling and safety outputs.
- Automation systems with integrated safety monitoring.
