Why Choose the Pizzato NSE4ZZ1SA5-F41 Safety Interlock Switch?
The Pizzato NSE4ZZ1SA5-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 range used to protect operators and control access to hazardous machinery.
This device is typically installed on safety doors, hinged guards, sliding panels, and machine access points. It ensures machinery cannot operate while a guard is open, supporting compliance with EN ISO 14119 and modern functional safety standards used in automated production environments.
The NSE4ZZ1SA5-F41 uses a high-level coded F41 RFID actuator system, meaning it recognizes only a uniquely paired actuator. This provides strong protection against tampering, bypass attempts, 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.
- Robust industrial-grade technopolymer housing.
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.
- SA5 configuration designed for flexible industrial installation and wiring options.
- M12 connector interface (typical NS series architecture).
Advanced Machine Guard Safety Control
The NSE4ZZ1SA5-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 met, while the RFID system verifies the presence of the correct F41-coded actuator.
This makes it suitable for demanding industrial environments where high reliability, 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.
- Machine access safety interlocking systems.
