Why Choose the Pizzato NG 2D7D411E-F31 Safety Switch with Lock?
The Pizzato NG 2D7D411E-F31 is an NG series RFID safety switch with guard locking and integrated control devices, designed for monitoring movable machine guards and controlling access to hazardous areas. It combines coded actuator detection, electronically monitored locking, safety outputs and local operator controls in a robust metal assembly for industrial machinery and automated equipment.
This configuration incorporates two integrated operator pushbuttons: a white 1NO+1NC pushbutton in position 1 and a black 1NO+1NC pushbutton in position 2. The switch uses the D working method, meaning the actuator remains locked when the solenoid is de-energised, while Mode 1 safety-output activation requires the actuator to be inserted and locked before the safety outputs become active.
The NG 2D7D411E-F31 provides a 9750 N locking force, two safety inputs, two electronic safety outputs and separate signalling outputs for actuator-inserted and actuator-locked status. It is supplied complete with the VN NG-F31 high-coding-level actuator and features a metal housing with three threaded M20 × 1.5 conduit entries plus a rotating head with an escape pushbutton.
Key Advantages
- Combines RFID guard monitoring, guard locking and integrated operator controls in one assembly.
- 9750 N locking force supports secure retention of guarded machine access points.
- Integrated white and black 1NO+1NC pushbuttons provide convenient local machine-control functions.
- VN NG-F31 high-coding-level actuator provides enhanced protection against inappropriate actuator substitution.
- D working method keeps the actuator locked while the solenoid is de-energised.
- Two safety inputs and two electronic safety outputs facilitate integration with suitable safety controllers.
- Separate O3 and O4 outputs provide actuator-inserted and actuator-locked status information.
- Rotating head with escape pushbutton provides an emergency egress function from within a guarded area.

RFID Guard Locking with Integrated Operator Controls
The Pizzato NG 2D7D411E-F31 combines safety-related guard monitoring with operator-control functions directly at the guarded access point. Its white and black 1NO+1NC pushbuttons can be incorporated into the machine control architecture, helping reduce the requirement for separately mounted operator devices while keeping essential controls conveniently positioned beside the guard.
Mode 1 operation means the OS1 and OS2 safety outputs are active when the actuator is inserted and locked. Separate O3 and O4 outputs provide actuator-presence and locking-status information, while the supplied F31 actuator provides a high coding level for applications where increased protection against foreseeable manipulation of the guard-interlocking system is required.
Typical Applications
- Industrial machine safety doors and movable guards.
- Robotic cells and automated production areas.
- Packaging and processing machinery.
- Machine tools with residual hazardous movement.
- Automated assembly and manufacturing equipment.
- Conveyor and material handling systems.
- Guarded work areas requiring an internal escape release.
- OEM machinery requiring integrated local operator controls.
