Why Choose the Pizzato NG 2D1E421G-F31 Safety Switch with Lock?
The Pizzato NG 2D1E421G-F31 is an advanced NG series safety switch with guard locking and integrated control device, supplied complete with a high-coded actuator. Designed for industrial machine guarding, it combines electronic safety monitoring, robust guard locking and a local operator pushbutton within a durable metal housing.
As part of the Pizzato NG series, the NG 2D1E421G-F31 provides two safe inputs and two safe outputs for integration with modern machine-safety controllers. Its E working principle locks the actuator when the electromagnet is energised, while dedicated O3 and O4 signalling outputs separately indicate actuator insertion and locking status.
This configuration incorporates a single green pushbutton with 1NO + 1NC contacts and is supplied complete with the VN NG-F31 high-coding-level actuator. With a maximum holding force of 9750 N, an orientable head and three M20 × 1.5 threaded cable entries, it provides a robust solution for guarded industrial machinery requiring controlled access and local operator interaction.

Reliable Guard Locking and Electronic Safety Monitoring
Safety switches with guard locking allow industrial safety systems to monitor protective guards while retaining the actuator when access to hazardous machine areas must be controlled. The Pizzato NG series combines electronic safety inputs and outputs with electromagnet-operated locking and independent status signalling, enabling the machine controller to monitor both guard position and lock condition.
The NG 2D1E421G-F31 uses Mode 2 safety-output activation, with OS1 and OS2 active when the actuator is inserted, while the separate O4 output provides locking-status information. Its integrated green pushbutton, high-coded VN NG-F31 actuator and robust metal construction make it suitable for automated machinery requiring dependable guard monitoring and convenient local control.
