Why Choose the Pizzato NG 2D7D431A Safety Switch with Lock?
The Pizzato NG 2D7D431A is an industrial NG series RFID safety switch with guard locking designed for monitoring and controlling access through movable guards, doors and protected areas of machinery. Its electronic safety architecture combines coded actuator detection with monitored locking, making it suitable for demanding machine-safety and automation applications.
This configuration uses Mode 3 safety-output activation: OS1 is associated with the inserted-and-locked actuator condition, while OS2 is associated with the inserted actuator condition. Separate O3 and O4 signalling outputs provide additional information for actuator insertion and locking status, allowing the machine control system to distinguish between a closed guard and a securely locked guard.
The NG 2D7D431A uses the D working method, with the actuator locked when the solenoid is de-energised. It features a rotating head with escape pushbutton, a robust metal housing and a maximum NG series holding force of 9750 N. This exact base SKU is supplied without an actuator, allowing the appropriate NG actuator to be selected separately for the application.
Key Advantages
- Combines RFID guard monitoring and high-force guard locking in one industrial safety device.
- Mode 3 safety-output operation provides separate locking and interlocking functionality.
- NG series locking mechanism provides a maximum holding force of 9750 N.
- De-energised-to-lock D working method keeps the actuator locked when the solenoid is not energised.
- Separate signalling outputs indicate actuator inserted and actuator locked conditions.
- Rotating head with escape pushbutton supports guarded areas where personnel may enter the protected space.
- Robust metal housing provides IP67 and IP69K protection.
- Supplied without actuator, allowing a compatible NG actuator to be selected separately.

Mode 3 Guard Monitoring and Locking
The NG 2D7D431A uses Mode 3 output logic to provide differentiated monitoring of the guard and locking mechanism. The electronic architecture allows one safety-output channel to supervise the inserted-and-locked condition while the other supervises actuator insertion, providing both locking and interlocking information for an appropriately designed machine safety system.
With a maximum holding force of 9750 N, IP67 and IP69K environmental protection and an escape-release pushbutton, the NG 2D7D431A is suited to robust industrial guarding applications. Because this base article is supplied without an actuator, machine builders can select a compatible NG actuator separately according to the required coding strategy and installation design.
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.
- Guarded machinery requiring separate interlocking and lock-monitoring information.
