Why Choose the Pizzato NSD5SE1SMK-F41 Safety Interlock Switch?

The Pizzato NSD5SE1SMK-F41 is a high-security RFID safety interlock switch with guard locking designed for demanding industrial machine safety applications. As part of the advanced Pizzato NS NS-series safety locking switch platform, it delivers reliable actuator recognition, robust electromechanical locking, and high-integrity safety signal feedback for automated machinery.

This model features a de-energised solenoid locking mechanism combined with high-level RFID coding (F41), ensuring strong resistance against tampering and guaranteeing that machine guards remain securely locked during hazardous operation. It is engineered for use in safety-critical industrial environments where compliance, durability, and reliability are essential.

With its rugged technopolymer housing, compact industrial footprint, and high ingress protection rating, the NSD5SE1SMK-F41 is ideal for robotic systems, packaging machinery, conveyors, and OEM automation equipment requiring certified guard locking and safety monitoring.

Key Advantages

  • High-security RFID-coded actuator system (F41 high coding level) for strong anti-tamper protection.
  • Solenoid-driven guard locking with fail-safe de-energised release principle.
  • Dual-channel safety outputs (OS1/OS2) for redundant safety monitoring.
  • Integrated diagnostic outputs for guard status and locking condition feedback.
  • Compliant with modern machine safety standards such as EN ISO 14119.
  • Suitable for series connection in safety circuits maintaining high PL/SIL performance.

Key Features

  • Pizzato NS-series RFID safety interlock switch.
  • Model: NSD5SE1SMK-F41.
  • High-level coded RFID actuator (F41).
  • Guard locking via de-energised solenoid principle.
  • M12 multi-pole industrial connector interface.
  • Safety outputs OS1/OS2 with diagnostic channels (O3/O4).
  • Enhanced internal configuration variant (D5 safety architecture family).

Reliable Machine Safety and Guard Control

The Pizzato NSD5SE1SMK-F41 ensures machinery cannot operate unless protective guards are correctly closed and locked. Once the RFID-coded actuator is detected and locking is engaged, the safety outputs enable machine operation under controlled conditions.

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

Typical Applications

  • Robotic safety cells and automation enclosures.
  • Packaging and high-speed production machinery.
  • Conveyor and material handling systems.
  • OEM machine building and industrial equipment.
  • Automated manufacturing systems requiring guard locking.
  • Safety-critical industrial automation environments.
