NG 2D7E621A Pizzato NG series safety switch with lock

Why Choose the Pizzato NG 2D7E621A Safety Switch?

The Pizzato NG 2D7E621A 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 E working principle uses an energised solenoid to lock the actuator, helping prevent access to hazardous machine areas while dangerous movements or processes are active. The rotating head incorporates an escape pushbutton, providing a means of releasing the guard from inside the protected area when required. The switch is supplied without an actuator, allowing a compatible Pizzato NG RFID actuator to be selected separately.

The NG 2D7E621A uses activation mode 2, with the safety outputs becoming active when the compatible actuator is inserted. It provides two safety inputs, two safety outputs, actuator-inserted signalling and a fault output, together with dedicated inputs for solenoid activation and actuator programming or reset.

Key Advantages

• Advanced RFID safety switch with solenoid guard locking.

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 compatible actuator while the electronic safety outputs communicate the guard status to a safety PLC or suitable safety module.

The NG 2D7E621A 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 O3 provides actuator-inserted signalling and O4 provides fault indication. The integrated 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.
