Why Choose the Pizzato NG 2D5D412M-F31 Safety Switch?
The Pizzato NG 2D5D412M-F31 is an advanced safety switch with guard locking, integrated control devices and high-level coded actuator, designed for reliable monitoring and locking of movable guards on industrial machinery. Part of the Pizzato NG series, it combines electronically coded actuator detection, high-force guard locking, electronic safety outputs and local operator controls within one robust industrial assembly.
This exact configuration incorporates two integrated push buttons: a blue push button with 1NO+1NC contacts in position 1 and a white push button with 1NC+1NO contacts in position 2. It uses working principle D, meaning the actuator remains locked when the electromagnet is de-energised, while the orientable head incorporates a key-operated auxiliary release for controlled manual unlocking when required.
The NG 2D5D412M-F31 is supplied complete with the VN NG-F31 high-level coded actuator and provides a holding force of 9750 N. Its powder-coated metal housing, three M20 × 1.5 threaded cable entries, IP65 protection for the integrated-control configuration and comprehensive electronic safety interface make it suitable for demanding automated machinery and industrial production equipment.
Key Advantages
- Combines guard monitoring, guard locking and two local operator controls within one device.
- Supplied with VN NG-F31 high-level coded actuator for enhanced resistance to interlock manipulation.
- 9750 N holding force supports secure retention of industrial machine guards.
- Power-to-release working principle D keeps the actuator locked when the electromagnet is de-energised.
- Integrated blue and white 1NO+1NC push buttons provide convenient local machine-control functions.
- Key-operated auxiliary release provides controlled manual release of the guard-locking mechanism.

Reliable Guard Monitoring for Industrial Machinery
Pizzato NG safety locking switches are designed for machinery where movable guards must be electronically monitored and physically retained while hazardous functions remain active. The coded actuator provides reliable guard detection, while the power-to-release locking mechanism keeps the access point mechanically secured when the electromagnet is de-energised.
The NG 2D5D412M-F31 combines this safety architecture with dual safe inputs and outputs, dedicated actuator and lock-status signals and two integrated push buttons. The blue and white operator controls allow machine functions to be positioned directly at the guarded access point, while the key-operated auxiliary release provides a controlled method of manually releasing the locking mechanism when required.
Typical Applications
- Industrial machine guard doors and access panels.
- Robotic cells and automated production equipment.
- Packaging and processing machinery.
- Automated manufacturing and assembly lines.
- CNC machines and industrial machine tools.
- Conveyor and material handling systems.
- Machinery requiring power-to-release guard locking and integrated local operator controls.
