NG 2D7E431A Pizzato NG series safety switch with lock

Why Choose the Pizzato NG 2D7E431A Safety Switch?

The Pizzato NG 2D7E431A is a robust RFID safety switch with solenoid guard locking, designed for reliable monitoring and protection of machine guards, access doors and hazardous areas in industrial automation systems. As part of the advanced Pizzato NG safety switch series, it combines non-contact RFID actuator detection, electronic safety monitoring and guard locking in a durable metal housing.

The NG 2D7E431A uses the E working principle, with the actuator locked by an energised solenoid and an integrated escape release button for emergency release from inside the protected area. The device uses high-performance electronic safety outputs to monitor actuator insertion and locking status, providing a reliable interface with suitable safety control systems.

This version uses activation mode 3, where one safety output becomes active when the actuator is inserted and locked, while the second safety output becomes active when the actuator is inserted. The switch is supplied without an actuator, allowing the appropriate Pizzato NG RFID actuator to be selected separately for the installation.

Reliable Machine Guarding and Safety Control

The Pizzato NG series combines RFID actuator recognition with electronic safety monitoring and guard locking to provide a dependable interface between machine guards and safety control systems. The non-contact RFID technology detects the associated actuator while the electronic safety outputs communicate guard status to a safety PLC or suitable safety module.

The NG 2D7E431A uses the E working principle, meaning the actuator is locked when the solenoid is energised. Its activation mode 3 configuration provides differentiated safety signals for actuator insertion and locking, allowing the safety controller to distinguish between a guard that is closed and one that is correctly locked. The escape pushbutton provides a means of releasing the guard from inside the protected area when required.

Typical Applications

• Machine guarding and safety access doors.
• Industrial production and processing machinery.
• Automated manufacturing systems.
• Packaging and material handling equipment.
• Robotic cells and automated workstations.
• Machines with hazardous movement or stored energy.
• Safety circuits requiring RFID-coded guard locking.
• Industrial machinery requiring monitored access protection.
