NS D4ST1DMK-F40 Pizzato NS series safety locking switch, with actuator

Why Choose the Pizzato NS D4ST1DMK-F40 Safety Locking Switch?

The Pizzato NS D4ST1DMK-F40 is an advanced RFID safety interlock switch with guard locking designed for monitoring and securing movable guards, doors and access points on industrial machinery. Part of the Pizzato NS series safety interlock switches, it combines electronic actuator detection with controlled guard locking in a compact solution for modern machine safety systems.

This configuration is supplied with an F40 low-level coded RFID actuator, providing reliable electronic detection while allowing interchangeable actuators from the corresponding coded family. The NS platform incorporates redundant electronic safety outputs and dedicated control and signalling functions, enabling straightforward integration with safety PLCs, safety modules and industrial automation systems.

The NS D4ST1DMK-F40 uses operating principle D, meaning the actuator remains locked when the electromagnet is de-energised. This power-to-unlock arrangement is well suited to machinery where the protective guard must remain mechanically secured until the safety control system determines that access can be permitted.

Key Advantages

• Integrated RFID guard monitoring and electromagnetic guard locking.
• Supplied with an F40 low-level coded RFID actuator.
• Low-level coding enables interchangeable compatible actuators.
• Principle D power-to-unlock operation retains the actuator when the electromagnet is de-energised.
• Redundant electronic safety outputs support integration with machine safety controllers.
• Dedicated signalling functions allow guard and locking conditions to be monitored by the control system.
• NS series design provides a robust solution for automated machinery and guarded production equipment.

Reliable RFID Guard Monitoring and Locking

Safety interlock switches with guard locking are used where opening a protective guard before hazardous machine conditions have ended could expose personnel to risk. The Pizzato NS series combines electronic RFID actuator recognition with a mechanical locking function, allowing the safety control system to supervise the position of the guard and control when access can be permitted.

With principle D operation, the NS D4ST1DMK-F40 retains its actuator while the electromagnet is de-energised. The supplied F40 actuator provides low-level RFID coding for applications where interchangeable compatible actuators are appropriate, while the electronic safety architecture supports integration into industrial machine safety systems.

Typical Applications

• Industrial machine guard doors and access panels.
• Robotic cells and automated production systems.
• Packaging and processing machinery.
• Automated assembly equipment.
• Conveyor and material handling systems.
• Machine tools and enclosed manufacturing machinery.
• Safety systems requiring controlled access to hazardous machine areas.
