NG 2D7D621A-F31 Pizzato NG series safety switch with lock, with actuator

Why Choose the Pizzato NG 2D7D621A-F31 Safety Switch?

The Pizzato NG 2D7D621A-F31 is an advanced RFID safety switch with guard locking designed for secure monitoring and controlled access to movable guards, doors and protective barriers on industrial machinery. Part of the Pizzato NG series, it combines coded non-contact actuator detection, electronic safety monitoring and guard locking in a robust industrial safety device.

This model uses the D working method, with the actuator locked while the solenoid is de-energised. Its electronic safety architecture provides two safety inputs and two safety outputs, while dedicated signalling functions provide information about actuator insertion and the locking condition. The switch also supports safety-system integration up to PL e and SIL 3 when correctly incorporated into an appropriate safety circuit.

The NG 2D7D621A-F31 is supplied with a VN NG-F31 high-coding-level RFID actuator. The F31 actuator is individually coded so that the associated switch recognises its paired actuator, providing enhanced resistance to actuator substitution. The rotating head with escape pushbutton provides an internal release facility for appropriately designed guarded areas.

Key Advantages

• Combines RFID guard monitoring and guard locking in one industrial safety switch.
• High-coding-level VN NG-F31 actuator provides individually coded actuator recognition.

Reliable Safety Control for Industrial Machinery

Pizzato NG series RFID safety locking switches are designed for machinery where hazardous conditions may remain after the machine has been stopped, for example because of mechanical inertia, pressure or high temperatures. The locking function prevents the associated guard from being opened while the machine safety system requires continued protection.

The NG 2D7D621A-F31 uses a high-coding-level F31 actuator and electronic safety architecture to provide reliable guard monitoring without mechanical actuator contacts. Its mode 2 configuration activates OS1 and OS2 when the actuator is inserted, while O3 and O4 provide additional signalling for actuator insertion and fault status. The two safety outputs can also be incorporated into NG series safety chains while maintaining demanding safety performance when correctly designed and monitored.

Typical Applications

• Industrial machine guards and access doors.

• Packaging and processing machinery.
• Machine tools and machining centres.
• Assembly and production lines.
• Conveyor and material handling equipment.
• Protective gates around hazardous machinery.
• Machinery with hazardous run-down or residual energy.
• OEM equipment requiring RFID guard monitoring and guard locking.
