Why Choose the Pizzato NSD4SE1SMK-F40 Safety Interlock Switch?
The Pizzato NSD4SE1SMK-F40 is a robust RFID safety interlock switch with solenoid locking, engineered for reliable machine guarding in industrial automation environments. Manufactured by Pizzato Elettrica, it belongs to the NS series safety switch family designed to protect operators and ensure machinery only runs when safety guards are securely closed.
This model is commonly used on safety doors, hinged guards, sliding panels, and machine access points. It ensures hazardous equipment cannot operate while the guard is open, supporting compliance with EN ISO 14119 machine safety standards.
The NSD4SE1SMK-F40 uses a low-level coded F40 RFID actuator system, meaning all F40 actuators share the same coding and are interchangeable within the same system family, simplifying installation and maintenance in industrial applications.
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 safety-critical environments.
- High mechanical durability for demanding applications.
- Dual-channel safety outputs for PLC integration.
- Integrated status feedback for door and lock monitoring.
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-grade sealed housing for harsh environments.
- Designed for machine safety applications in automated systems.
Reliable Machine Guard Safety Control
The NSD4SE1SMK-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 ease of replacement, maintenance flexibility, and operational reliability are important. The switch integrates with PLC safety systems for real-time monitoring of guard and lock status.
Typical Applications
- Industrial automation production lines.
- Robotics safety fencing systems.
- CNC machinery and machining centres.
- Packaging and processing equipment.
- Material handling and conveyor systems.
- Safety doors, guards, and access panels.
