Why Choose the Pizzato NSD4ST1DA10-F41 Safety Interlock Switch?
The Pizzato NSD4ST1DA10-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 switch family 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 prevents machinery from operating while the guard is open, ensuring compliance with EN ISO 14119 machine safety standards and supporting modern functional safety architectures.
The NSD4ST1DA10-F41 uses a high-level coded F41 RFID actuator system, meaning it recognises only a single uniquely paired actuator for maximum anti-tamper protection and high safety integrity in demanding industrial environments.
Key Advantages
- High-security RFID safety interlock with solenoid locking.
- F41 high-level coded actuator for maximum tamper resistance.
- Designed for industrial machine safety systems and automation cells.
- Reliable dual-channel safety outputs for PLC integration.
- Integrated monitoring of door position and lock status.
- Robust industrial construction 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) for safety PLC integration.
- Actuator insertion and lock status signalling outputs.
- Integrated auxiliary release function for emergency access (DA10 configuration).
- Industrial sealed housing for demanding environments.
Advanced Machine Guard Safety Control
The NSD4ST1DA10-F41 ensures machinery remains safely disabled whenever guards are open or not correctly secured. The solenoid locking mechanism 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-integrity industrial environments where safety, reliability, and controlled access are essential. The auxiliary release function provides controlled emergency access when required, depending on system configuration.
Typical Applications
- Industrial automation production lines.
- Robotics safety cells and machine guarding systems.
- CNC machinery and machining centres.
- Packaging and processing equipment.
- Material handling and conveyor systems.
- High-security safety doors, guards, and access panels.
