Why Choose the Pizzato NSD4SE1SPK-F40 Safety Interlock Switch?
The Pizzato NSD4SE1SPK-F40 is a compact and reliable 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 switch range used to protect operators and ensure machines operate only when safety guards are securely closed.
This model is typically installed on safety doors, hinged guards, sliding panels, and machine access points. It prevents hazardous machinery from operating while the guard is open, helping support compliance with EN ISO 14119 functional safety requirements.
The NSD4SE1SPK-F40 uses a low-level coded F40 RFID actuator system, meaning all F40 actuators share the same coding and are interchangeable within the same family. This simplifies installation, replacement, and maintenance in industrial environments.
Key Advantages
- Reliable RFID safety interlock with solenoid locking for machine guarding.
- F40 low-level coded actuator system allows interchangeable actuators for easy maintenance.
- Designed for industrial automation and machine safety applications.
- Robust construction for harsh industrial environments.
- Dual-channel safety outputs for PLC and safety relay integration.
- Integrated monitoring of door and lock status.
Key Features
- Pizzato NS series safety interlock switch with locking function.
- Solenoid locking mechanism with fail-safe de-energised release principle.
- RFID-coded actuator system (F40 type).
- 2 safety outputs (OS1–OS2).
- Actuator insertion and lock status signalling outputs.
- Compact industrial housing for machine integration.
- Designed for general-purpose machine safety applications.
Reliable Machine Guard Safety Control
The NSD4SE1SPK-F40 ensures machinery remains safely disabled whenever guards are open or not properly secured. The solenoid locking mechanism prevents access until safe operating conditions are achieved, while the RFID system reliably detects actuator presence within the F40 coding family.
This makes it suitable for general industrial automation environments where reliability, ease of replacement, and cost-effective maintenance are important. The switch integrates with safety PLCs for real-time monitoring of guard status and lock condition.
Typical Applications
- Industrial automation production lines.
- Robotics safety cells and machine guarding systems.
- CNC machinery and tooling equipment.
- Packaging and processing machinery.
- Material handling and conveyor systems.
- Safety doors, guards, and access panels.
