Why Choose the Pizzato NSD4ST1SA2-F40 Safety Interlock Switch?

The Pizzato NSD4ST1SA2-F40 is a robust RFID safety interlock switch with guard locking designed for industrial machine safety applications where reliable access control and consistent guard monitoring are essential. It is part of the proven Pizzato NS NS-series safety locking switch family, engineered for secure actuator recognition, solenoid-based locking, and dependable safety signal feedback in automated systems.

This model operates using a de-energised solenoid locking principle combined with low-level RFID coding (F40), providing reliable but flexible actuator recognition for standard machine safety applications. It ensures guards remain securely locked during hazardous machine operation and supports compliance with EN ISO 14119 requirements.

With its compact technopolymer housing, industrial sealing, and IP67/IP69K protection rating, the NSD4ST1SA2-F40 is widely used in robotic cells, packaging machinery, conveyors, and OEM automation systems requiring dependable guard locking and safety interlocking performance.

Key Advantages

  • Low-level RFID-coded actuator system (F40 coding) for flexible actuator pairing.
  • Solenoid guard locking with fail-safe de-energised release principle.
  • Dual safety outputs (OS1/OS2) for redundant guard monitoring. ([ledcontrols.co.uk](https://www.ledcontrols.co.uk/ns-d4st1sa2-f40-pizzato-ns-series-safety-locking-switch-with-actuator.html?utm_source=chatgpt.com))
  • Integrated diagnostic outputs for actuator and lock status (O3/O4 depending on variant). ([sonepar.fr](https://www.sonepar.fr/catalog/fr-fr/products/pizzato-interrupteur-de-securite-avec-verrouillage-serie-ns-avec-actionneur-02250155657?utm_source=chatgpt.com))
  • Designed for integration into PL e / SIL safety architectures in industrial automation systems.
  • Suitable for series connection in safety chains for complex machinery systems.

Key Features

  • Pizzato NS-series safety interlock switch with locking.
  • Model: NSD4ST1SA2-F40.
  • RFID low coding actuator recognition (F40).
  • De-energised solenoid guard locking (fail-safe design).
  • M12 industrial connector or cable variant (depending on configuration).
  • Safety outputs OS1/OS2 for redundant monitoring.
  • Auxiliary release function for maintenance and emergency access.

Reliable Machine Guarding and Safety Control

The Pizzato NSD4ST1SA2-F40 ensures machinery only operates when protective guards are properly closed and monitored. When the RFID-coded actuator is detected and locking is engaged, the safety outputs allow controlled machine operation under safe conditions.

If the guard is opened or the locking condition is removed, the system triggers an immediate safe stop. Continuous diagnostics monitor actuator and lock status, ensuring safe integration into PLC-based safety systems in industrial automation environments.

Typical Applications

  • Industrial automation machinery.
  • Robotic safety enclosures.
  • Packaging and production systems.
  • Conveyor and material handling systems.
  • OEM machine building applications.
  • General machine safety guarding systems.
