Why Choose the Pizzato NG 2D1E521D-F31 Safety Switch with Lock?
The Pizzato NG 2D1E521D-F31 is an advanced NG series safety switch with guard locking and integrated control devices, supplied complete with a high-coded actuator. Designed for industrial machine guarding, it combines electronic safety monitoring, robust guard locking and local operator controls within a durable metal housing.
As part of the Pizzato NG series, the NG 2D1E521D-F31 provides two safe inputs and two safe outputs together with dedicated actuator-position and locking-status signalling. It also incorporates an EDM feedback input for monitoring external devices, while its E working principle locks the actuator when the electromagnet is energised.
This configuration incorporates a white pushbutton with 1NO + 1NC contacts, a black pushbutton with 1NO + 1NC contacts and a red emergency-stop pushbutton with turn-to-release action and 2NC contacts. It is supplied complete with the VN NG-F31 high-coding-level actuator, providing a comprehensive solution for guarded machinery requiring access monitoring, guard locking and integrated local controls.

Reliable Guard Locking with External Device Monitoring
Safety switches with guard locking allow industrial safety systems to monitor protective guards while controlling access to hazardous machine areas. The Pizzato NG series combines electronic safety inputs and outputs with electromagnet-operated locking and independent status signalling, allowing the machine controller to determine both guard position and locking condition.
The NG 2D1E521D-F31 additionally provides EDM feedback for monitoring compatible external switching devices. Combined with its high-coded actuator, integrated operator pushbuttons, emergency-stop control and Mode 2 safety-output logic, this makes the switch a comprehensive solution for automated machinery requiring dependable guard monitoring and flexible safety-system integration.
Typical Applications
- Industrial machine guard doors and access panels.
- Robotic cells and automated manufacturing systems.
- Packaging and processing machinery.
- Automated assembly and production lines.
- Conveyor and material handling equipment.
- Machine tools and manufacturing equipment.
- Guarding systems requiring integrated emergency-stop functionality.
- Machine-safety systems requiring high-coded actuator identification and EDM feedback.
