Why Choose the Pizzato NSD5AZ1SMK-F40 Safety Interlock Switch?
The Pizzato NSD5AZ1SMK-F40 is a robust RFID safety interlock switch with solenoid locking, designed for industrial machine guarding applications where reliable access control and operator safety are essential. Manufactured by Pizzato Elettrica, it belongs to the NS series safety switch family widely used in automation and machine safety systems.
This device is typically installed on safety doors, hinged guards, sliding panels, and access covers. It ensures hazardous machinery cannot operate while a guard is open, supporting compliance with EN ISO 14119 safety standards and modern functional safety requirements.
The NSD5AZ1SMK-F40 uses a low-level coded F40 RFID actuator system, meaning all F40 actuators are interchangeable within the same coding family. This simplifies maintenance and replacement while maintaining reliable safety performance.
Key Advantages
- Reliable RFID safety interlock with solenoid locking.
- F40 low-level coded actuator system for easy interchangeability.
- Designed for industrial automation and machine safety applications.
- Dual-channel safety outputs for PLC and safety relay integration.
- Integrated monitoring of door position and lock status.
- Compact and durable industrial housing for harsh environments.
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 low-level coding).
- 2 safety outputs (OS1–OS2).
- Actuator insertion and lock status signalling outputs.
- AZ configuration housing for flexible mounting options.
- Industrial sealed design for demanding environments.
Reliable Machine Guard Safety Control
The NSD5AZ1SMK-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 detects the presence of a compatible F40-coded actuator.
This makes it suitable for cost-effective industrial automation environments where safety performance, flexibility, and easy maintenance are important. It integrates easily with safety PLCs and control systems for continuous monitoring of guard status.
Typical Applications
- Industrial automation production lines.
- Robotics safety guarding systems.
- CNC machinery and machine tools.
- Packaging and processing equipment.
- Material handling and conveyor systems.
- Safety doors, guards, and access panels.
