Why Choose the Pizzato NSE5ZZ1SA4-F41 Safety Interlock Switch?
The Pizzato NSE5ZZ1SA4-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 belongs to the NS series safety interlock family used to protect operators and ensure controlled access to hazardous machinery.
This device is typically installed on safety doors, hinged guards, sliding panels, and machine access points. It prevents machinery from operating while a guard is open, supporting compliance with EN ISO 14119 functional safety standards and modern PL/SIL safety architectures used in industrial environments.
The NSE5ZZ1SA4-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 installations.
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.
- Rugged industrial housing for harsh 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 monitoring outputs.
- SA4 configuration designed for flexible wiring and expanded I/O options in NS series systems.
- M12 connector interface (typical NS series architecture).
Advanced Machine Guard Safety Control
The NSE5ZZ1SA4-F41 ensures machinery remains safely stopped 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 demanding industrial environments where high reliability, strong tamper resistance, and functional safety compliance are required.
Typical Applications
- Industrial automation production lines.
- Robotics safety guarding systems.
- CNC machinery and tooling equipment.
- Packaging and processing machinery.
- Material handling systems and conveyors.
- High-security machine access control systems.
