Why Choose the Pizzato NS D4AZ1SRK-N194 Safety Locking Switch?

The Pizzato NS D4AZ1SRK-N194 is a high-performance RFID safety locking switch with integrated control devices designed for secure monitoring and locking of machine guards in industrial automation environments. As part of the reliable Pizzato NS series safety interlock switches, it combines coded RFID actuator technology with guard locking and integrated operator controls for advanced machine safety applications.

The NS series provides a complete safety solution for hazardous machinery access points where the guard must remain locked until safe conditions are achieved. The switch uses a high coding level RFID actuator system, helping prevent unauthorised bypassing while providing reliable status monitoring for modern safety circuits.

The NS D4AZ1SRK-N194 features a de-energised solenoid locking principle, dual-channel safety outputs and integrated control devices including illuminated push buttons and an emergency stop function. It is designed for direct integration into industrial safety systems using M12 connectivity.

Key Advantages

  • Advanced RFID-coded safety locking technology for machine guard protection.
  • Integrated control devices reduce panel space requirements and simplify machine interfaces.
  • De-energised solenoid locking keeps the actuator locked when power is removed.
  • High coding level actuator detection improves resistance against safety device bypassing.
  • Dual-channel safety outputs support modern safety architectures.
  • Compact NS series design suitable for demanding industrial automation applications.

Key Features

  • Pizzato NS RFID safety locking switch series.
  • Product type: Safety switch with lock and integrated control devices.
  • RFID high coding level actuator technology.
  • Working principle: D method, actuator locked by de-energised solenoid.
  • Safety outputs: 2 × OS1–OS2.
  • Safety inputs: 2 × IS1–IS2.
  • Signalling outputs: O3 actuator inserted and O4 actuator locked.
  • Integrated illuminated push button controls.
  • Integrated emergency stop button with rotary release.
  • Two M12 connector configuration.

Reliable RFID Machine Safety Control

RFID safety locking switches such as the Pizzato NS D4AZ1SRK-N194 provide secure access protection by combining coded actuator recognition with mechanical guard locking. This allows machines to prevent access to hazardous areas until safe operating conditions have been established.

The integrated control devices make the NS series suitable for compact machine designs where safety functions and operator commands need to be combined in a single industrial device. Its diagnostic outputs and safety channels support efficient integration into modern automation systems.

Typical Applications

  • Industrial machine safety guarding.
  • Automated production and assembly lines.
  • Packaging and processing machinery.
  • Robotic cells and manufacturing systems.
  • Protective doors and access panels.
  • OEM machine building applications.
