Why Choose the Pizzato NG 2D7D411D-F31 Safety Switch with Lock?
The Pizzato NG 2D7D411D-F31 is an advanced RFID safety switch with guard locking and integrated control devices designed for monitoring and controlling access to hazardous areas of industrial machinery. Part of the Pizzato NG series, it combines coded non-contact actuator detection, robust guard locking, electronic safety outputs and local operator controls within a single metal-bodied safety device.
This configuration uses principle D operation, meaning the actuator is locked when the locking solenoid is de-energised. It provides two safety inputs, two OSSD safety outputs and dedicated signalling outputs for actuator insertion and locking status. Safety outputs operate in activation mode 1, becoming active when the actuator is both inserted and locked.
The NG 2D7D411D-F31 incorporates three integrated control devices: a white 1NO + 1NC pushbutton, a black 1NO + 1NC pushbutton and a red emergency-stop pushbutton with turn-to-release operation and 2NC contacts. It is supplied complete with the VN NG-F31 high-level coded actuator and features a rotating head with escape pushbutton for enhanced machine-access safety.
Key Advantages
- Combines RFID guard monitoring, guard locking and operator controls in one device.

Reliable Guard Locking for Industrial Machinery
Guard-locking safety switches are particularly important on machinery where hazardous conditions can continue after a stop command, such as equipment containing rotating components, high-temperature processes or stored pressure. The NG 2D7D411D-F31 monitors the coded actuator and mechanically retains the guard, allowing access to be managed through the machine's safety-related control system.
The combination of RFID actuator detection, a 9750 N locking force, OSSD safety outputs and integrated operator controls makes this NG series switch suitable for sophisticated automated equipment. Its emergency-stop control and escape pushbutton also provide important local safety functions at guarded machine access points.
Typical Applications
- Machine guard doors and safety access gates.
- Robotic cells and automated manufacturing systems.
- Packaging and processing machinery.
- Machine tools with hazardous run-down times.
- Conveyor and material handling installations.
- Automated assembly and production equipment.
- Guarded areas requiring integrated emergency-stop and operator controls.
