Why Choose the Pizzato NSD4CE1SMK-F40 Safety Interlock Switch?
The Pizzato NSD4CE1SMK-F40 is a robust RFID-coded safety interlock switch with solenoid locking, designed for industrial machine guarding and high-reliability safety applications. Manufactured by Pizzato Elettrica, it belongs to the NS series safety range used to protect operators and ensure machines operate only when guards are correctly closed and secured.
This device is commonly installed on safety doors, hinged guards, sliding panels, and access points in automated machinery. It ensures the machine cannot start while the guard is open, helping meet international safety requirements such as EN ISO 14119.
The NSD4CE1SMK-F40 uses a low-level coded F40 RFID actuator system, meaning all F40 actuators share the same coding and can be interchangeably recognized by the switch. This makes it easier to replace or service components in industrial environments where downtime must be minimized.
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 machinery safety compliance.
- High mechanical durability for demanding environments.
- Dual-channel safety monitoring for controller integration.
- Integrated status feedback for door and lock position.
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.
- Auxiliary signalling outputs for actuator status monitoring.
- Industrial-grade sealed housing for harsh environments.
- Designed for machine safety applications in automated systems.
Reliable Machine Guard Safety Control
The NSD4CE1SMK-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 ensures consistent detection of actuator presence across compatible F40 devices.
This makes it suitable for general industrial automation environments where reliability, ease of maintenance, and fast replacement of components are important. The switch integrates with PLCs and safety controllers for real-time monitoring of guard and lock status.
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.
