Why Choose the Pizzato NSE4ZZ1SA20-F41 Safety Interlock Switch?
The Pizzato NSE4ZZ1SA20-F41 is a high-security RFID safety interlock switch with solenoid locking designed for machine guarding and access control in industrial automation systems. Manufactured by Pizzato Elettrica, it belongs to the NS series safety interlock family used to protect operators and ensure safe machine operation.
This device is typically installed on safety doors, hinged guards, sliding panels, and machine access points. It prevents machinery from operating while the guard is open, supporting compliance with EN ISO 14119 functional safety standards and modern PL/SIL safety architectures used in industrial environments.
The NSE4ZZ1SA20-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, actuator substitution, and unauthorized access in safety-critical applications.
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.
- Continuous monitoring of guard position and lock status.
- Robust technopolymer housing for harsh industrial 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 inserted and lock status signalling outputs.
- SA20 configuration designed for enhanced wiring flexibility and installation layout within NS series architecture.
- M12 industrial connector interface (typical NS series configuration).
Advanced Machine Guard Safety Control
The NSE4ZZ1SA20-F41 ensures machinery remains safely disabled whenever guards are open or not properly secured. The solenoid locking system prevents access until safe operating conditions are achieved, while the RFID system verifies the presence of the correct F41-coded actuator.
This makes it suitable for high-demand industrial environments where strong tamper resistance, controlled access, and functional safety compliance are required.
Typical Applications
- Industrial automation production lines.
- Robotics safety guarding systems.
- CNC machines and tooling equipment.
- Packaging and processing machinery.
- Material handling and conveyor systems.
- High-security machine access control systems.
