Why Choose the Pizzato NG 2D6D411E Safety Switch with Lock?
The Pizzato NG 2D6D411E is an advanced NG series safety switch with guard locking and integrated control devices designed for monitoring and controlling access to hazardous areas of industrial machinery. Combining electronic safety monitoring, solenoid-operated guard locking and local operator controls in a robust assembly, it provides machine builders with an effective solution for safety-critical guard doors and access points.
The NG 2D6D411E incorporates two integrated control devices: a white pushbutton with 1NO+1NC contacts and a black pushbutton with 1NO+1NC contacts. Its electronic interface provides two safety inputs IS1-IS2, two safety outputs OS1-OS2 and dedicated O3 and O4 signalling outputs for actuator-inserted and actuator-locked status, supporting straightforward integration with suitable machine safety controllers.
Using Principle D operation, the actuator is locked when the solenoid is de-energised. Safety-output activation uses Mode 1, so the OS safety outputs become active when the actuator is both inserted and locked. The switch features a durable metal housing, three M20×1.5 threaded conduit entries and a rotating head equipped with an auxiliary key-release device and escape pushbutton. This specific NG 2D6D411E configuration is supplied without an actuator, allowing the appropriate actuator to be selected separately for the installation.
Key Advantages
- Combines guard locking, electronic safety monitoring and operator controls in one assembly.
- Principle D locking keeps the actuator locked with the solenoid de-energised.
- Mode 1 safety operation requires the actuator to be inserted and locked before the safety outputs become active.
- Two integrated pushbuttons provide convenient local machine-control functions.
- Dual safety inputs and dual OS safety outputs support modern safety-control architectures.
- Separate signalling outputs indicate actuator inserted and actuator locked status.
- Rotating head with auxiliary key release and escape pushbutton supports flexible machine-guard installations.
- Robust metal housing with IP65 protection for industrial environments.

Reliable Guard Locking and Operator Control for Industrial Machinery
Guard-locking safety switches are used where a movable guard must remain securely locked while hazardous machine conditions are present. The Pizzato NG series combines electronic guard monitoring with solenoid-operated locking, enabling a safety control system to determine whether the actuator is correctly inserted and whether the protective guard has been locked before permitting hazardous operation.
The NG 2D6D411E further simplifies machine design by incorporating two operator pushbuttons directly into the switch assembly. Its Mode 1 safety-output logic, dedicated guard-status outputs, robust metal enclosure and auxiliary and escape-release functions make it particularly suitable for automated equipment where dependable access control and convenient local operation are required.
Typical Applications
- Industrial machine guard doors and access gates.
- Robotic cells and automated production systems.
- Packaging and processing machinery.
- Conveyor and material handling equipment.
- Machine tools and manufacturing equipment.
- Guarded machinery requiring integrated local operator controls.
- Safety-critical access points requiring monitored guard locking.
