Why Choose the Pizzato NSE4TE1SMK-F41 Safety Interlock Switch?
The Pizzato NSE4TE1SMK-F41 is a high-performance RFID safety interlock switch with solenoid locking designed for advanced machine guarding applications in industrial automation systems. Manufactured by Pizzato Elettrica, it is part of the NS series safety interlock family used to protect operators and ensure safe access control to hazardous machinery.
This device is commonly installed on safety doors, hinged guards, sliding panels, and access covers in automated production environments. It prevents machinery from operating while a guard is open, supporting compliance with EN ISO 14119 and modern functional safety standards.
The NSE4TE1SMK-F41 uses a high-level coded F41 RFID actuator system, meaning it only operates with a uniquely paired actuator. This provides strong protection against tampering, bypassing, and unauthorized access in safety-critical systems.
Key Advantages
- High-security RFID safety interlock with solenoid locking.
- F41 high-level coded actuator system for maximum anti-tamper protection.
- Designed for industrial machine safety and automation systems.
- Dual-channel safety outputs for PLC and safety relay integration.
- Real-time monitoring of guard position and lock status.
- Robust industrial housing for demanding environments.
Key Features
- Pizzato NS series safety interlock switch with locking function.
- Solenoid locking mechanism with fail-safe de-energised release principle.
- High-level coded RFID actuator system (F41 type).
- 2 safety outputs (OS1–OS2).
- Actuator insertion and lock status signalling outputs.
- SMK configuration designed for standard industrial mounting and wiring layout.
- Industrial sealed housing suitable for harsh environments.
Advanced Machine Guard Safety Control
The NSE4TE1SMK-F41 ensures machinery remains safely disabled whenever guards are open or not properly secured. The solenoid locking mechanism prevents access until safe operating conditions are achieved, while the RFID system validates the presence of the correctly paired F41-coded actuator.
This makes it ideal for high-security industrial environments where strong tamper resistance and controlled access are essential.
Typical Applications
- Industrial automation production lines.
- Robotics safety guarding systems.
- CNC machining and tooling equipment.
- Packaging and processing machinery.
- Material handling and conveyor systems.
- High-security machine access control systems.
