Why Choose the Pizzato NSE4ZZ1DA2-F41 Safety Interlock Switch?
The Pizzato NSE4ZZ1DA2-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 control access to hazardous machinery.
This device is typically installed on safety doors, hinged guards, sliding panels, and access points on automated machinery. It prevents machine operation while a guard is open, supporting compliance with EN ISO 14119 functional safety standards and high safety integrity levels used in modern industrial systems.
The NSE4ZZ1DA2-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, bypass attempts, and unauthorized access in safety-critical environments.
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 technopolymer 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 insertion and lock status signalling outputs.
- DA2 configuration designed for industrial mounting and wiring flexibility within the NS series architecture.
- M12 industrial connector interface (typical NS series implementation).
Advanced Machine Guard Safety Control
The NSE4ZZ1DA2-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 validates the presence of the correctly paired F41-coded actuator.
This makes it suitable for high-security industrial automation environments where strong tamper resistance, controlled access, and functional safety compliance are essential.
Typical Applications
- Industrial automation production lines.
- Robotics safety guarding systems.
- CNC machining and tooling equipment.
- Packaging and processing machinery.
- Material handling systems and conveyors.
- High-security machine access control systems.
