Why Choose the Pizzato NG 2D6D411C Safety Switch with Lock?
The Pizzato NG 2D6D411C is an advanced NG series safety switch with guard locking and integrated control devices designed for monitoring and securing movable guards on industrial machinery. It combines RFID-based guard detection, electromagnetic locking and local operator controls in a robust metal housing, providing machine builders with a comprehensive solution for guarded access points.
This configuration uses Principle D, with the actuator locked when the solenoid is de-energised. It provides two safety inputs and two safety outputs together with dedicated signalling outputs for actuator-inserted and actuator-locked status, allowing straightforward integration with compatible safety PLCs, safety relays and industrial automation systems.
The NG 2D6D411C incorporates a white pushbutton, yellow pushbutton and red emergency-stop button directly into the cover. Its rotating head also includes a key-operated auxiliary release and escape pushbutton, while the metal housing provides three M20 × 1.5 threaded conduit entries and IP65 protection. This base configuration is supplied without an actuator, allowing the appropriate NG-series actuator to be selected separately.
Key Advantages
- Combines guard monitoring, electromagnetic locking and integrated operator controls in one safety device.
- Principle D operation keeps the actuator locked while the solenoid is de-energised.
- Two safety inputs and two safety outputs support modern machine safety architectures.
- Dedicated outputs signal actuator inserted and actuator locked conditions.
- Integrated white and yellow pushbuttons plus red emergency-stop control reduce the need for separate operator stations.
- Rotating head incorporates both auxiliary release and escape release functions.
- Robust metal housing with three M20 × 1.5 threaded entries suits demanding industrial installations.

Reliable Guard Monitoring and Locking for Industrial Machinery
The Pizzato NG series combines RFID-based actuator detection with electromagnetic guard locking to help control access to hazardous machine areas. On the NG 2D6D411C, Mode 1 operation makes the safety outputs active when the actuator is both inserted and locked, allowing the connected safety system to verify that the guard has reached its intended protected condition.
Integrated operator controls provide start, command and emergency-stop functionality directly at the guarded access point, while the auxiliary key release and escape pushbutton provide additional release functions. The combination of safety inputs, redundant safety outputs and dedicated status signalling makes the NG 2D6D411C suitable for integration into sophisticated automated machine safety systems.
Typical Applications
- Guard doors on automated production machinery.
- Robotic cells and automated assembly systems.
- Packaging and processing machinery.
- Conveyor and material handling systems.
- Machine tools and manufacturing equipment.
- Guarded areas requiring integrated operator and emergency-stop controls.
