Why Choose the Pizzato NSD3TE1SA2-F40 Safety Interlock Switch?
The Pizzato NSD3TE1SA2-F40 is a high-reliability 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 family used to ensure safe access control and protection of operators working near hazardous machinery.
This device is typically installed on safety doors, hinged guards, sliding panels, and machine access points. It prevents machinery from operating while a guard is open, supporting compliance with EN ISO 14119 machine safety standards and modern functional safety requirements.
The NSD3TE1SA2-F40 uses a low-level coded F40 RFID actuator system, meaning it recognises any compatible F40 actuator. This makes it more flexible for maintenance and replacement while still maintaining reliable machine safety performance.
Key Advantages
- Reliable RFID safety interlock with solenoid locking.
- F40 low-level coded actuator system for flexible interchangeability.
- Designed for industrial machine safety and automation systems.
- Dual-channel safety outputs for PLC and safety relay integration.
- Integrated monitoring of door position and lock status.
- Robust 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.
- TE1 configuration with rear escape release function for emergency exit capability.
- SA2 variant layout optimized for installation flexibility and wiring configuration.
Advanced Machine Guard Safety Control
The NSD3TE1SA2-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.
The integrated escape release function provides an important safety feature, allowing controlled exit from inside a safeguarded area in emergency situations. This makes it suitable for applications where personnel may be enclosed within machine guarding systems.
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, access panels, and enclosed machine cells.
