Why Choose the Pizzato NG 2D7D411X-F31 Safety Switch with Lock?
The Pizzato NG 2D7D411X-F31 is an NG series RFID safety switch with guard locking and integrated control devices, designed for industrial machinery where access to hazardous areas must be controlled until safe conditions are established. It combines coded non-contact guard detection, monitored locking and local operator-control functionality in a robust metal assembly.
This model uses the D working principle, meaning the actuator remains locked while the electromagnet is de-energised. It provides two safety inputs IS1–IS2, two safety outputs OS1–OS2, an O3 output for actuator-inserted status and an O4 output for actuator-locked status, together with dedicated electromagnet activation and programming/reset inputs.
The NG 2D7D411X-F31 operates in Mode 1, with the safety outputs active when the actuator is inserted and locked. It is supplied with the VN NG-F31 high-coding-level actuator, provides an actuator holding force of 9750 N, and features an orientable head with an anti-panic escape pushbutton for guarded areas where an internal release facility is required.
Key Advantages
- Combines RFID guard monitoring, guard locking and integrated control devices in one assembly.
- 9750 N actuator holding force provides robust retention of guarded machine access points.
- VN NG-F31 high-coding-level actuator provides enhanced protection against inappropriate actuator substitution.
- D working principle keeps the actuator locked when the electromagnet is de-energised.
- Two safety inputs and two electronic safety outputs support integration with modern machine safety systems.
- Separate O3 and O4 outputs provide actuator-inserted and actuator-locked status information.
- Orientable head with anti-panic escape pushbutton provides an internal release facility.
- Metal housing and three M20 × 1.5 cable entries provide a robust installation platform for industrial machinery.

RFID Guard Locking with High-Level Coded Actuator
The Pizzato NG series is intended for machinery where hazardous conditions can remain after a stop command, such as equipment with mechanical inertia, hot components or pressurised processes. Guard locking allows access to remain controlled while the safety-related control system determines whether the guard can be released.
On the NG 2D7D411X-F31, Mode 1 operation requires the actuator to be inserted and locked for the safety outputs to become active. The supplied VN NG-F31 actuator provides high-level coding, while O3 and O4 provide separate diagnostic information for actuator presence and locking status to assist machine-control and safety-system integration.
Typical Applications
- Industrial machine safety doors and movable guards.
- Robotic cells and automated manufacturing areas.
- Packaging and processing machinery.
- Machine tools with hazardous residual movement.
- Automated assembly and production equipment.
- Conveyor and material handling systems.
- Guarded areas requiring an internal anti-panic escape release.
- OEM machinery requiring guard locking and integrated local controls.
