Why Choose the Pizzato NG 2D7D313O-F31 Safety Switch with Lock?
The Pizzato NG 2D7D313O-F31 is an advanced NG series safety switch with guard locking and integrated control devices, designed for monitoring and controlling movable guards, safety doors and access points on industrial machinery. It combines electronically monitored guard locking, coded actuator detection and local operator-control functionality in a robust metal assembly for demanding machine safety applications.
This model uses the Pizzato D working principle, meaning the actuator is locked when the electromagnet is de-energised. It provides two safety inputs and two electronic safety outputs, together with dedicated signalling outputs for actuator-inserted and actuator-locked status. Mode 1 operation means the safety outputs are active when the actuator is both inserted and locked.
The NG 2D7D313O-F31 provides a locking force of 9750 N and features a metal, powder-coated housing with three threaded M20 × 1.5 cable entries. It is supplied complete with a VN NG-F31 high-level coded actuator and incorporates an orientable head with emergency escape functionality for industrial guarded-access applications.
Key Advantages
- Combines guard monitoring, guard locking and integrated control devices in one assembly.
- 9750 N locking force supports secure retention of industrial machine guards.

Reliable Guard Locking for Industrial Machinery
Guard-locking safety switches help prevent access to hazardous machine areas while dangerous conditions remain. The Pizzato NG series combines coded actuator detection with electronically monitored locking and safety outputs, enabling the guard condition to form part of a modern safety-related machine control system.
For the NG 2D7D313O-F31, Mode 1 operation requires the actuator to be both inserted and locked before the OS1 and OS2 safety outputs become active. Separate O3 and O4 signalling outputs provide actuator and locking status information, while the high-level coded F31 actuator and integrated release functions support secure and practical machine guarding.
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 machinery requiring emergency escape functionality.
- OEM machinery and industrial automation systems.
