Why Choose the Pizzato NG 2D7E411A Safety Switch with Lock?
The Pizzato NG 2D7E411A is an industrial NG series RFID safety switch with guard locking designed to monitor and control access through movable guards, safety doors and protected areas of machinery. Its electronic architecture combines coded actuator detection with monitored guard locking, providing a robust safety solution for automated machinery and demanding industrial applications.
This configuration provides two safety inputs IS1-IS2 and two safety outputs OS1-OS2, together with an O3 signalling output for actuator-inserted status and an O4 signalling output for actuator-locked status. The safety outputs use Mode 1, becoming active when the actuator is inserted and locked, enabling the secured guard condition to be incorporated into an appropriate machine safety system.
The NG 2D7E411A uses the E working principle, with the actuator locked when the solenoid is energised. It features a rotating head with escape pushbutton, metal housing, IP67 and IP69K protection and an NG series maximum holding force of 9750 N. This base SKU is supplied without an actuator, allowing a compatible NG actuator to be selected separately for the required coding level.
Key Advantages
- Combines RFID guard monitoring and high-force guard locking in one industrial safety device.
- Provides up to 9750 N maximum actuator holding force.
- E working principle locks the actuator when the solenoid is energised.
- Mode 1 safety-output activation monitors the inserted-and-locked guard condition.
- Two safety inputs and two safety outputs support integration with suitable machine safety controllers.

Energised Guard Locking for Industrial Machinery
The Pizzato NG 2D7E411A combines RFID actuator recognition with electronically monitored guard locking for machinery where controlled access is required. Its Mode 1 configuration activates the OS1 and OS2 safety outputs when the actuator is inserted and locked, while separate O3 and O4 signalling outputs allow the machine control system to monitor actuator insertion and locking status.
The E working principle energises the solenoid to lock the actuator. Together with a maximum holding force of 9750 N, IP67 and IP69K environmental protection and an escape-release head, this makes the NG 2D7E411A suitable for robust industrial guarding applications. Because the base article is supplied without an actuator, the required compatible NG actuator can be selected separately according to the machine's coding and installation requirements.
Typical Applications
- Industrial machine safety doors and movable guards.
- Robotic cells and automated manufacturing systems.
- Packaging and processing machinery.
- Material handling and conveyor installations.
- Assembly and production equipment.
- Machine tools and protected manufacturing cells.
- OEM machinery requiring RFID guard monitoring and controlled access.
