Why Choose the Pizzato NG 2D9D423G-F31 Safety Switch?
The Pizzato NG 2D9D423G-F31 is a robust RFID safety switch with solenoid guard locking and integrated control devices, designed for reliable monitoring and protection of machine guards, access doors and hazardous areas in industrial automation systems. As part of the advanced Pizzato NG safety switch series, it combines non-contact RFID actuator detection, electronic safety monitoring, guard locking and integrated operator controls in a durable industrial housing.
The D working principle keeps the actuator locked when the solenoid is de-energised, providing a fail-safe locking arrangement for applications where the guard must remain secured following loss of electrical power. The remote escape release allows the guard to be released from inside the protected area when correctly installed, while the supplied F31 high-coded RFID actuator provides a dedicated actuator association to help prevent manipulation.
The NG 2D9D423G-F31 is designed for demanding machine safety applications where coded guard monitoring, guard locking and integrated control devices are required. Its electronic safety outputs, robust metal construction and high ingress protection make it suitable for integration into modern industrial safety circuits and automated machinery.

Reliable Machine Guarding and Safety Control
The Pizzato NG series combines RFID actuator recognition with electronic safety monitoring and guard locking to provide a dependable interface between machine guards and safety control systems. The non-contact RFID technology detects the high-coded actuator while the electronic safety outputs communicate guard status to a suitable safety PLC or safety module.
The NG 2D9D423G-F31 uses the D working principle, meaning the actuator remains locked when the solenoid is de-energised. Its activation mode 2 configuration enables the safety outputs when the actuator is inserted, while signalling outputs provide information about actuator and locking status. The remote escape release allows personnel inside the protected area to release the guard when required, while integrated control devices provide additional machine interaction directly from the switch assembly.
Typical Applications
- Machine guarding and safety access doors.
- Industrial production and processing machinery.
- Automated manufacturing systems.
- Packaging and material handling equipment.
- Robotic cells and automated workstations.
- Machines with hazardous movement or stored energy.
- Safety circuits requiring RFID-coded guard locking.
- Industrial machinery requiring integrated operator controls.
- Machinery requiring remote escape release from guarded areas.

Frequently Asked Questions
What is the Pizzato NG 2D9D423G-F31 used for?
The Pizzato NG 2D9D423G-F31 is an RFID safety switch used to monitor and lock machine guards and access doors, with integrated control devices and remote escape release.
How does the D working principle operate?
The D working principle keeps the actuator locked when the 24 V DC solenoid is de-energised, providing guard locking that is maintained when electrical power is removed.
What type of actuator is supplied with the NG 2D9D423G-F31?
The switch is supplied with a VN NG-F31 high-coded RFID actuator. The high coding level provides a dedicated actuator association for enhanced protection against actuator substitution.
What does activation mode 2 mean on the NG 2D9D423G-F31?
Activation mode 2 means the safety outputs become active when the actuator is inserted, allowing the switch to communicate the guard status to an appropriate safety control system.
Does the NG 2D9D423G-F31 include an escape release?
Yes. The switch incorporates a remote escape release mechanism that can be used to release the guard from inside the protected area when correctly installed.
