Why Choose the Pizzato NSD4SE1SPK-F40 Safety Interlock Switch?
The Pizzato NSD4SE1SPK-F40 is a robust 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 range used to protect operators and ensure machines operate only when safety guards are securely closed.
This model is commonly installed on safety doors, hinged guards, sliding panels, and machine access points. It prevents hazardous machinery from operating while the guard is open, supporting compliance with EN ISO 14119 machine safety standards and modern industrial safety architectures.
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, simplifying 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 easier maintenance.
- Designed for industrial automation and general machine safety applications.
- Compact and robust construction for harsh environments.
- Dual-channel safety outputs for PLC and safety relay integration.
- Integrated monitoring of door status and lock condition.
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) for safety controller integration.
- Actuator insertion and lock status signalling outputs.
- Industrial sealed housing for demanding environments.
- Designed for machine safety applications in automation systems.
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 using the F40 shared-coding system.
This makes it suitable for cost-effective industrial automation environments where flexibility, easy replacement, and reliable safety monitoring are required. It integrates easily with safety PLCs and control systems for real-time guard and lock status feedback.
Typical Applications
- Industrial automation production lines.
- Robotics safety fencing and guarding systems.
- CNC machinery and machining centres.
- Packaging and processing equipment.
- Material handling and conveyor systems.
- Safety doors, guards, and access panels.
