NG 2D7E411L-F31 Pizzato NG series safety switch with lock and integrated control devices, with actuator

Why Choose the Pizzato NG 2D7E411L-F31 Safety Switch?

The Pizzato NG 2D7E411L-F31 is a robust and intelligent RFID safety switch with solenoid guard locking designed for reliable monitoring and protection of machine guards in industrial automation and safety applications. As part of the advanced Pizzato NG safety switch series, it combines coded RFID actuator detection, guard locking and integrated control devices in a compact metal housing.

This safety switch uses non-contact RFID technology to identify the associated actuator while providing monitored guard locking. The D7E working principle provides locking with an energised solenoid and incorporates an anti-panic release button, allowing the guard to be released from inside the protected area when required. The integrated control-device configuration further simplifies machine safety installation.

Supplied with a high-coded F31 RFID actuator, the NG 2D7E411L-F31 is designed to recognise its specific paired actuator, providing enhanced protection against actuator manipulation. Its metal housing, IP67 and IP69K protection and suitability for safety applications up to PL e, SIL 3 and Category 4 make it suitable for demanding industrial machinery.

Key Advantages

• Advanced RFID-coded safety switch with solenoid guard locking.
• High-level F31 actuator coding helps prevent unauthorised actuator substitution.
• D7E working principle provides locking with an energised solenoid.
• Integrated anti-panic release button for emergency release from the protected area.
• Integrated control devices reduce the need for separate machine control components.
• Safety performance up to PL e, SIL 3 and Category 4 when correctly integrated.
• Robust metal construction with IP67 and IP69K protection.

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 switch detects the coded actuator without mechanical contact and provides safety outputs according to the configured operating mode.

The NG 2D7E411L-F31 uses an energised-solenoid locking principle and includes an anti-panic release button. Its F31 actuator provides high-level coding, meaning the switch is associated with one specific actuator and another F31 actuator is not recognised unless a new association procedure is performed. The integrated safety inputs and OSSD outputs allow the device to be incorporated into modern machine safety systems, including installations with multiple NG switches connected in series.
