NG 2D5D411H Pizzato NG series safety switch with lock and integrated control devices

Why Choose the Pizzato NG 2D5D411H Safety Switch with Lock?

The Pizzato NG 2D5D411H is an advanced NG series RFID safety switch with guard locking and an integrated control device for industrial machine-safety applications. It combines non-contact RFID actuator detection, electromagnetic guard locking and local operator control within a robust metal housing.

This configuration uses the D working principle, meaning the actuator is locked while the locking electromagnet is de-energised. Its Mode 1 safety logic activates the OS1 and OS2 safety outputs when the actuator is inserted and locked, while separate O3 and O4 signalling outputs provide actuator-inserted and actuator-locked status information.

The NG 2D5D411H incorporates a single white pushbutton with 1NO + 1NC contacts and features an orientable head with auxiliary key release. The switch provides a maximum holding force of 9750 N and is supplied without an actuator, allowing the appropriate compatible NG actuator to be selected separately for the application.

Key Advantages

• Combines RFID guard monitoring, electromagnetic locking and local operator control in one device.
• 9750 N maximum holding force provides robust guard retention.
• D working principle retains the actuator while the locking electromagnet is de-energised.
• Mode 1 safety logic requires the actuator to be inserted and locked for safety-output activation.
• Integrated white pushbutton with 1NO + 1NC contacts provides convenient local operator control.
• Auxiliary key release provides a means of manually releasing the locking mechanism when required by the machine design.
• Separate O3 and O4 signalling outputs provide actuator-position and locking-status information.
• Robust powder-coated metal housing supports demanding industrial installations.
• Supplied without actuator for flexibility when selecting the appropriate NG actuator separately.

RFID Guard Monitoring with De-Energised Locking

The Pizzato NG 2D5D411H combines RFID actuator detection with electromagnetic guard locking so that a machine-safety system can monitor a movable guard while controlling access to hazardous areas. Its D working principle retains the actuator while the locking electromagnet is de-energised, while Mode 1 logic enables the OS1 and OS2 safety outputs when the actuator is both inserted and locked.

An auxiliary key-release mechanism is incorporated into the orientable head to provide manual release of the locking mechanism when required by the machine design. Separate O3 and O4 outputs allow the control system to distinguish between an inserted actuator and a locked actuator, while the integrated white pushbutton provides local operator-control functionality directly at the guarded access point.

Typical Applications

• Industrial machine guard doors and access panels.
• Robotic cells and automated manufacturing systems.
• Packaging and processing machinery.
• Automated assembly and production lines.
• Conveyor and material-handling systems.
• Machine tools and production equipment.
• Guarding systems requiring de-energised electromagnetic locking.
• Machinery requiring auxiliary key-release functionality.
• Guarded access points requiring an integrated local pushbutton.
• Machine-safety systems requiring separate actuator and lock-status signalling.
