Why Choose the Pizzato NS D4ST1DA2-F41 Safety Locking Switch?

The Pizzato NS D4ST1DA2-F41 is a high-performance RFID safety interlock switch with guard locking designed to monitor and secure movable guards, doors and access points on industrial machinery. Part of the Pizzato NS series, this configuration combines electronic safety monitoring, electromagnetic locking and a high-level coded RFID actuator for dependable machine guarding.

The switch is supplied complete with a VN NS-F41 high-level coded RFID actuator, providing enhanced protection against actuator substitution. It incorporates 2 safe inputs, 2 redundant safety outputs and dedicated signalling outputs for actuator-inserted and actuator-locked status, providing comprehensive information to the machine safety and control system.

The NS D4ST1DA2-F41 uses operating principle D, meaning the actuator remains locked while the electromagnet is de-energised. With a maximum holding force of 2100 N, IP67 / IP69K environmental protection and an orientable front key-operated auxiliary release, it provides a robust solution for controlled access to hazardous machine areas.

Key Advantages

  • Combines RFID guard monitoring and electromagnetic locking in one safety device.
  • Supplied with a VN NS-F41 high-level coded RFID actuator.
  • High-level actuator coding helps protect against unauthorised or incorrect actuator substitution.
  • 2100 N maximum holding force for secure machine guarding.
  • 2 redundant safety outputs, OS1–OS2, for safety control integration.
  • Dedicated outputs provide actuator-inserted and actuator-locked status.
  • IP67 / IP69K protection supports use in demanding industrial environments.
  • Front key-operated auxiliary release provides controlled manual unlocking when required.

Key Features

  • Pizzato NS series safety interlock switch with guard locking.
  • VN NS-F41 high-level coded RFID actuator supplied.
  • Principle D: actuator locked with electromagnet de-energised.

  • 2 safe inputs: IS1–IS2.
  • 2 safe outputs: OS1–OS2.
  • Actuator-inserted signalling output: O3.
  • Actuator-locked signalling output: O4.
  • 2 electromagnet activation inputs: IE1–IE2.
  • Programming / reset input: I3.
  • 2100 N maximum holding force.
  • Orientable front key-operated auxiliary release.
  • Side cable or connector connection direction.
  • IP67 according to EN 60529 and IP69K according to ISO 20653.

Reliable High-Level RFID Guard Monitoring and Locking

Safety interlock switches with guard locking are used where access to a hazardous machine area must remain restricted until the safety control system determines that the guard can be released. The Pizzato NS series combines RFID-based actuator recognition with electromagnetic locking and electronic safety outputs, enabling both guard position and locking status to be incorporated into the machine safety system.

The NS D4ST1DA2-F41 uses a high-level coded F41 actuator and principle D locking, retaining the actuator while the electromagnet is de-energised. Its O3 and O4 signalling outputs separately communicate actuator-inserted and actuator-locked conditions, while the redundant IS and OS channels support integration into sophisticated industrial safety architectures.

Typical Applications

  • Industrial machine guard doors and access panels.
  • Robotic cells and automated manufacturing systems.
  • Packaging and processing machinery.
  • Automated assembly and production equipment.
  • Conveyor and material handling systems.
  • Machine tools and enclosed manufacturing equipment.
  • Safety applications requiring high-level coded actuator recognition.

Frequently Asked Questions

What is the Pizzato NS D4ST1DA2-F41 used for?

The Pizzato NS D4ST1DA2-F41 is designed to monitor and lock movable machine guards and access doors, helping prevent access to hazardous machine areas until the safety system permits release.

Is an actuator supplied with the NS D4ST1DA2-F41?

Yes. The switch is supplied complete with a VN NS-F41 high-level coded RFID actuator.

What coding level does the F41 actuator provide?

The F41 is a high-level coded RFID actuator, providing enhanced actuator identification for safety applications where protection against actuator substitution is important.

How does the NS D4ST1DA2-F41 locking mechanism operate?

The switch uses principle D, meaning the actuator remains locked while the electromagnet is de-energised.

What is the holding force of the NS D4ST1DA2-F41?

The safety locking switch provides a maximum holding force of 2100 N for secure retention of the machine guard.

What safety inputs and outputs are provided?

The NS D4ST1DA2-F41 provides 2 safe inputs IS1–IS2 and 2 safe outputs OS1–OS2, together with dedicated signalling and electromagnet control connections.

What do the O3 and O4 outputs indicate?

The O3 output signals that the actuator is inserted, while the O4 output signals that the actuator is locked, allowing the control system to monitor both conditions separately.

What protection rating does the NS D4ST1DA2-F41 provide?

The switch is rated IP67 according to EN 60529 and IP69K according to ISO 20653, supporting installation in demanding industrial environments.
