NG 2D7D311A-F31 Pizzato NG series safety switch with lock, with actuator

Why Choose the Pizzato NG 2D7D311A-F31 Safety Switch?

The Pizzato NG 2D7D311A-F31 is a heavy-duty RFID safety switch with guard locking, designed to monitor and secure movable guards on industrial machinery where access must remain prevented until hazardous conditions have ceased. Part of the advanced Pizzato NG series, it combines non-contact RFID actuator detection, powerful mechanical guard locking and electronic safety outputs within a robust metal housing.

This configuration is supplied complete with a VN NG-F31 high-level coded RFID actuator, which provides individual actuator recognition and enhanced protection against manipulation of the machine safety system. Two safe inputs and two semiconductor safety outputs allow straightforward integration with suitable safety PLCs and safety modules, while dedicated signalling outputs communicate actuator-inserted and actuator-locked status to the machine control system.

The NG 2D7D311A-F31 uses the D working principle, keeping the actuator locked while the electromagnet is de-energised. Its locking mechanism provides a maximum actuator holding force of 9750 N, while the safety outputs operate in Mode 1 and become active when the actuator is both inserted and locked. An orientable head with auxiliary lock release provides additional flexibility for installation and controlled machine access.

Key Advantages

• Combines RFID guard monitoring and high-strength mechanical guard locking in one industrial safety device.
• Supplied with a VN NG-F31 high-level coded RFID actuator for enhanced anti-tampering protection.
• Heavy-duty locking mechanism provides up to 9750 N actuator holding force.
• D working principle keeps the actuator locked while the electromagnet is de-energised.
• Mode 1 safety outputs are active only when the actuator is inserted and locked.
• Two safe inputs and two semiconductor safety outputs support integration with modern safety-control systems.
• Dedicated signalling outputs provide separate actuator-inserted and actuator-locked status.
• High-level RFID coding helps minimise the possibility of deliberate guard-system defeat.

Reliable Guard Control for Industrial Machinery

Safety locking switches such as the Pizzato NG 2D7D311A-F31 are particularly suited to machinery where hazardous conditions can continue after a stop command, including equipment with rotating components, mechanical inertia, elevated temperatures or pressure. The RFID system monitors the position and identity of the actuator while the mechanical interlock keeps the associated guard secured until opening is permitted.

The NG 2D7D311A-F31 uses Mode 1 safety-output operation, so its OS1 and OS2 safety outputs become active when the actuator is both inserted and mechanically locked. This configuration makes the switch suitable for applications where the safety control system must verify both guard closure and locking status before hazardous machine operation can be enabled.

Typical Applications

• Industrial machine guard doors and access gates.
• Robotic cells and automated manufacturing systems.
• Packaging and processing machinery.
• Automated assembly and production lines.
• Conveyor and material-handling systems.
• Machine tools with rotating or high-inertia components.
• Equipment where access must remain prevented until hazardous conditions have ceased.
• OEM machinery and integrated industrial safety systems.
