Why Choose the Pizzato NSE4ZZ1SA2-F41 Safety Interlock Switch?
The Pizzato NSE4ZZ1SA2-F41 is a high-reliability RFID safety interlock switch with solenoid locking designed for machine guarding applications in industrial automation systems. Manufactured by Pizzato Elettrica, it is part of the NS series of safety switches used to protect operators and control access to hazardous machinery.
This switch is typically installed on safety doors, hinged guards, sliding panels, and machine access covers. It prevents machine operation while the guard is open, supporting compliance with EN ISO 14119 and modern functional safety standards used in industrial environments.
The NSE4ZZ1SA2-F41 uses a high-level coded F41 RFID actuator system, meaning it only works with a uniquely paired actuator. This significantly increases protection against tampering, bypassing, 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 safety outputs for PLC and safety relay integration.
- Real-time monitoring of guard position and lock status.
- Robust industrial-grade 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.
- SA2 configuration designed for compact industrial mounting and wiring flexibility.
- M12 connector interface (typical NS series architecture).
Advanced Machine Guard Safety Control
The NSE4ZZ1SA2-F41 ensures machinery remains safely stopped whenever guards are open or not properly secured. The solenoid locking mechanism prevents access until safe conditions are met, while the RFID system validates the correct F41-coded actuator.
This makes it suitable for general industrial automation environments where reliable access control, safety compliance, and tamper resistance are required.
Typical Applications
- Industrial automation production lines.
- Robotics safety guarding systems.
- CNC machines and tooling equipment.
- Packaging and processing machinery.
- Material handling systems and conveyors.
- Machine access safety interlocking systems.
