Why Choose the Pizzato NG 2D7E511A-F31 Safety Switch with Lock?
The Pizzato NG 2D7E511A-F31 is a robust RFID safety switch with guard locking designed for reliable monitoring and locking of machine guards, doors and access points in industrial safety systems. As part of the advanced Pizzato NG series, it combines contactless RFID actuator detection with a high-strength electromechanical locking system for demanding machinery applications.
This model uses the E working principle, meaning the actuator is locked when the solenoid is energised. It incorporates a rotating head with an escape release pushbutton, allowing personnel inside a guarded area to release the locking mechanism in an emergency. The metal housing provides three threaded M20×1.5 conduit entries and is engineered for harsh industrial environments.
The NG 2D7E511A-F31 is supplied complete with the VN NG-F31 high-level coded RFID actuator. Its high coding level helps reduce the risk of bypassing the safety system, while the locking mechanism provides an actuator holding force of up to 9,750 N. The switch supports safety architectures up to PL e, SIL 3 and Category 4 when correctly integrated into a suitable safety control system.

Reliable Guard Locking for Industrial Machinery
RFID safety switches such as the Pizzato NG series provide non-contact detection of a coded actuator while also mechanically locking the associated guard. This combination allows a machine control system to verify that a protective door is both correctly closed and securely locked before hazardous machine functions are permitted.
The high-level coded F31 actuator is designed to recognise its specifically associated actuator, helping prevent deliberate or accidental bypassing of the safety function. Combined with the strong locking mechanism, dual safety outputs and dedicated status signals, the NG 2D7E511A-F31 is well suited to modern automated machinery requiring high levels of functional safety.
Typical Applications
- Machine guard and access-door interlocking.
- Automated production and assembly machinery.
- Packaging and processing equipment.
- Robotic cells and automated manufacturing systems.
- Material handling and conveyor systems.
- Machinery requiring personnel escape release from guarded areas.
