NG 2D7D511S-F31 Pizzato NG series safety switch with lock and integrated control devices, with actuator

Why Choose the Pizzato NG 2D7D511S-F31 Safety Switch?

The Pizzato NG 2D7D511S-F31 is an RFID safety switch with guard locking and integrated control devices designed for monitoring and controlling access to hazardous areas of industrial machinery. Part of the Pizzato NG series, it combines coded non-contact guard detection, electronic safety functions, guard locking and local operator controls within a robust industrial assembly.

The NG platform uses RFID technology to recognise the associated actuator without mechanical contact, providing dependable guard-position monitoring for automated machinery and safety systems. Its redundant electronic architecture supports high-level machine safety applications, while dedicated safety and signalling interfaces allow compatible controllers to evaluate guard and lock status.

The NG 2D7D511S-F31 is supplied with the VN NG-F31 high-coding-level actuator. The F31 actuator provides a high coding level according to EN ISO 14119, helping reduce the possibility of bypassing the safety function with an unauthorised actuator. A rotating head with escape pushbutton further supports applications where personnel may need to release the guard from inside a protected area.

Key Advantages

• Combines RFID guard monitoring, guard locking and integrated operator controls within one safety device.
• VN NG-F31 high-coding-level actuator provides enhanced coded identification of the associated machine guard.
• RFID detection operates without mechanical contact between the switch and coded actuator.
• NG series architecture can support safety functions up to PL e and SIL 3 when correctly integrated into the machine safety system.
• Dedicated electronic safety outputs simplify connection to compatible safety PLCs and controllers.
• Separate signalling functions provide useful guard and locking status information to the machine control system.
• Integrated control devices help consolidate safety interlocking and operator functions at the guarded access point.
• Rotating head with escape pushbutton provides an internal release facility for appropriately designed guarded areas.

Reliable Safety Control for Industrial Machinery

Pizzato NG series switches are designed for machinery where a protective guard must be monitored and, where required, kept locked until hazardous conditions have ceased. RFID actuator recognition provides coded electronic guard detection without mechanical contact, while the integrated locking system enables controlled access to protected machinery.

The NG 2D7D511S-F31 combines electronic safety monitoring, guard locking and local operator controls within one assembly. Its high-coding-level F31 actuator helps protect against inappropriate actuator substitution, while the redundant electronic architecture and safety outputs allow the switch to form part of safety functions designed to achieve demanding performance levels.

Typical Applications

• Industrial machine guards and access doors.
• Robotic cells and automated manufacturing systems.
• Packaging and processing machinery.
• Machine tools and machining centres.
• Assembly and production lines.
• Conveyor and material handling equipment.
• Protective gates around hazardous machinery.
• OEM equipment requiring integrated guard locking and operator controls.
