NG 2D5D411E-F31 Pizzato NG series safety switch with lock and integrated control devices, with actuator

Why Choose the Pizzato NG 2D5D411E-F31 Safety Switch with Lock?

The Pizzato NG 2D5D411E-F31 is a robust RFID safety switch with electromagnetic guard locking and integrated control devices designed for monitoring and controlling access to hazardous areas of industrial machinery. As part of the advanced Pizzato NG series, it combines coded actuator detection, guard locking, electronic safety outputs and operator controls within a durable metal enclosure.

This safety switch is supplied complete with a VN NG-F31 high-level coded actuator, providing enhanced protection against deliberate bypassing of the safety system. The NG 2D5D411E-F31 provides two safe inputs and two safe outputs, together with dedicated signalling outputs for actuator insertion and locking status, allowing straightforward integration with modern machine safety controllers and automation systems.

The NG 2D5D411E-F31 uses Principle D, meaning the actuator remains locked when the electromagnet is de-energised. It operates in Mode 1, with the OS1 and OS2 safety outputs active when the actuator is both inserted and locked. Two integrated operator controls, a white pushbutton and a black pushbutton each with 1NO+1NC contacts, provide convenient machine control directly at the guard switch.

Reliable Guard Locking and Operator Control for Industrial Machinery

Safety switches with guard locking are used to monitor movable guards and control access to hazardous areas of machinery. The Pizzato NG series combines RFID actuator detection with electronically controlled locking, allowing machine builders to integrate guard monitoring and locking functions into modern industrial safety architectures.

The NG 2D5D411E-F31 combines these safety functions with two integrated pushbuttons and a key-operated auxiliary release. Its Principle D locking arrangement keeps the guard locked when the electromagnet is de-energised, while Mode 1 operation activates the safety outputs when the actuator is inserted and locked, providing dependable status information to the machine safety system.

Typical Applications

• Industrial machine guard doors and access gates.
• Automated production and assembly machinery.
• Packaging and processing equipment.
• Robotic cells and automated manufacturing systems.
• Material handling and conveyor systems.
• Machine tools requiring integrated guard locking and operator controls.
