Why Choose the Pizzato NSD4CE1SA5-F41 Safety Interlock Switch?
The Pizzato NSD4CE1SA5-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 range engineered for reliable operator protection and controlled access to hazardous machinery.
This model is used to monitor safety doors, guards, and access panels, ensuring machinery cannot operate unless the guard is properly closed and securely locked. Its integrated locking system helps maintain safe isolation of equipment until all safety conditions are satisfied, supporting compliance with standards such as EN ISO 14119.
The NSD4CE1SA5-F41 uses a high-level coded F41 RFID actuator system, meaning it only recognises a single dedicated actuator for maximum anti-tamper protection and high safety integrity in industrial environments.
Key Advantages
- High-security RFID safety interlock with solenoid locking.
- F41 high-level coded actuator for maximum anti-tamper protection.
- Designed for demanding industrial machine safety systems.
- Reliable dual-channel safety outputs for controller integration.
- Integrated monitoring of door and lock status.
- Robust construction 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 insertion and lock status signalling outputs.
- Industrial sealed housing for harsh environments.
- Designed for high-risk machine safety applications.
Advanced Machine Guard Safety Control
The NSD4CE1SA5-F41 ensures machinery remains safely disabled whenever guards are open or not properly secured. The solenoid locking mechanism physically prevents access until safe operating conditions are achieved, while the RFID system ensures only the correct F41-coded actuator can operate the switch.
This makes it suitable for high-risk automation environments where safety integrity and tamper resistance are essential. The device integrates with PLCs and safety controllers to provide real-time monitoring of guard status and lock condition.
Typical Applications
- High-security industrial automation systems.
- Robotics safety cells and fenced machinery areas.
- CNC machining centres and tooling machines.
- Packaging and processing equipment.
- Automated production lines with strict safety requirements.
- Safety doors, guards, and restricted access panels.
