NG 2D7E421A Pizzato NG series safety switch with lock

Why Choose the Pizzato NG 2D7E421A Safety Switch?

The Pizzato NG 2D7E421A 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 2D7E421A uses the E working principle, with the actuator locked by an energised solenoid. Its rotating head incorporates an escape pushbutton, providing a means of releasing the guard from inside the protected area when required. The switch is designed for use with Pizzato NG RFID actuators and provides monitored guard locking for demanding machine safety applications.

This version operates with activation mode 2, where the safety outputs become active when the actuator is inserted. The switch provides two safety inputs, two safety outputs and dedicated signalling outputs for actuator insertion and locking status, allowing straightforward integration with suitable safety control systems.

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 2D7E421A uses the E working principle, meaning the actuator is locked when the solenoid is energised. Its activation mode 2 configuration enables the safety outputs when the actuator is inserted, while dedicated signalling outputs provide information about actuator insertion and locking. The rotating head and escape pushbutton make the device particularly suitable for guarded machinery where controlled access and personnel release are important.

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.
