Why Choose the Pizzato NSE4ZZ1DMK-F41 Safety Interlock Switch?
The Pizzato NSE4ZZ1DMK-F41 is a high-performance RFID safety interlock switch with solenoid locking designed for 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 equipment. It prevents machinery from operating while a guard is open, helping ensure compliance with EN ISO 14119 functional safety standards and achieving high safety performance levels used in modern industrial environments.
The NSE4ZZ1DMK-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 systems.
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.
- Real-time 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.
- DMK configuration designed for industrial mounting and wiring flexibility.
- M12 connector interface (typical NS series architecture).
Advanced Machine Guard Safety Control
The NSE4ZZ1DMK-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.
