Why Choose the Pizzato NSD4AZ1SM0.2 Safety Locking Switch?

The Pizzato NSD4AZ1SM0.2 is a robust RFID safety interlock switch with electromagnetic guard locking designed for monitoring and securing movable guards on industrial machinery. Part of the Pizzato NS Safety Locking Switch series, it combines contactless RFID actuator detection, monitored guard locking and electronic safety outputs for integration into modern machine safety circuits.

This model uses operating principle D, meaning the actuator is locked when the 24 V DC electromagnet is de-energised. It operates in Mode 1, with the OS1 and OS2 safety outputs active when the actuator is inserted and locked, allowing the safety control system to verify a secure guard condition before hazardous machine functions are enabled.

The NSD4AZ1SM0.2 provides a maximum 2,100 N actuator holding force and features a front screwdriver-operated auxiliary release. Its axial electrical connection uses a 0.2 m cable with an M12 connector, while the technopolymer housing and IP67 / IP69K protection provide durability for demanding industrial installations.

Key Advantages

  • Combines RFID guard detection and electromagnetic guard locking in one safety device.
  • Principle D locking retains the actuator when the 24 V DC electromagnet is de-energised.
  • Maximum 2,100 N holding force provides secure retention of movable machine guards.
  • Mode 1 safety operation monitors the inserted and locked actuator condition.
  • Dual safety inputs and outputs support integration into advanced machine safety circuits.
  • 0.2 m axial cable with M12 connector provides a convenient industrial connection arrangement.
  • IP67 / IP69K protection supports dependable use in demanding industrial environments.

  • 2,100 N maximum actuator holding force.
  • Two safety inputs: IS1 and IS2.
  • Two safety outputs: OS1 and OS2.
  • O3 signalling output for inserted actuator status.
  • O4 signalling output for locked actuator status.
  • Two electromagnet activation inputs: IE1 and IE2.
  • I3 programming / reset input.
  • 0.2 m axial cable with M12 connector.
  • Front screwdriver-operated auxiliary release.
  • Technopolymer housing with IP67 / IP69K protection.

Reliable RFID Guard Locking for Industrial Machinery

Safety interlock switches with guard locking are used where access to hazardous machinery must remain restricted until a safe condition has been established. The Pizzato NSD4AZ1SM0.2 combines contactless RFID detection with monitored electromagnetic locking, allowing a safety control system to verify that a compatible actuator is correctly inserted and locked before hazardous machine functions are permitted.

The NS series provides redundant electronic safety inputs and outputs and can be incorporated into safety architectures up to PL e and SIL 3 when correctly designed and validated. Its high holding force, robust environmental protection and compact axial cable-and-connector arrangement make the NSD4AZ1SM0.2 suitable for a wide variety of OEM machinery and automated production equipment.

Typical Applications

  • Industrial machine guard doors and access panels.
  • Robotic cells and automated manufacturing systems.
  • Packaging and processing machinery.
  • Machines with hazardous residual or run-down movement.
  • Automated assembly and production lines.
  • Conveyor and material handling equipment.
  • OEM machinery and integrated industrial safety systems.

Frequently Asked Questions

What is the Pizzato NSD4AZ1SM0.2 used for?

The NSD4AZ1SM0.2 is designed to monitor and lock movable machine guards, helping prevent access to hazardous machinery until the machine safety system permits the guard to be released.

Is an RFID actuator supplied with the NSD4AZ1SM0.2?

No. The NSD4AZ1SM0.2 is supplied without an actuator; a compatible Pizzato NS series RFID actuator is selected separately for the application.

How does the locking principle of the NSD4AZ1SM0.2 work?

The switch uses principle D, meaning the actuator is locked when the 24 V DC electromagnet is de-energised and released through controlled operation of the locking system.

What is the maximum holding force of the Pizzato NSD4AZ1SM0.2?

The locking mechanism provides a maximum actuator holding force of 2,100 N, helping retain the machine guard securely while access is prohibited.

What safety inputs and outputs does the NSD4AZ1SM0.2 provide?

The switch provides two safety inputs IS1–IS2 and two safety outputs OS1–OS2, together with O3 and O4 signalling outputs, IE1–IE2 electromagnet activation inputs and an I3 programming / reset input.

How is the Pizzato NSD4AZ1SM0.2 electrically connected?

The NSD4AZ1SM0.2 uses an axial 0.2 m cable with an M12 connector, providing a compact connection arrangement for industrial machinery.

What environmental protection does the NSD4AZ1SM0.2 provide?

The switch provides IP67 protection according to EN 60529 and IP69K protection according to ISO 20653, supporting operation in demanding industrial environments.
