NG 2D1D621A Pizzato NG series safety switch with lock

Why Choose the Pizzato NG 2D1D621A Safety Switch?

The Pizzato NG 2D1D621A is a robust RFID safety switch with guard locking designed for monitoring protected access points on industrial machinery and automated equipment. As part of the Pizzato NG series, it combines electronic actuator detection, monitored guard locking and electronic safety outputs within a durable metal housing for demanding machine safety applications.

This configuration uses working method D, with the actuator locked when the electromagnet is de-energised. The OS1 and OS2 safety outputs use activation mode 2 and are active when a compatible actuator is inserted. Dedicated signalling outputs provide actuator inserted status through O3 and fault information through O4, supporting integration with compatible machine safety controllers and automation systems.

The NG 2D1D621A is supplied without an actuator, allowing the appropriate NG series RFID actuator to be selected separately for the application. The switch provides a substantial 9750 N locking force and features auxiliary release, a rotating head, metal housing and three threaded M20 × 1.5 conduit entries for flexible installation on industrial machine guards and safety doors.

Key Advantages

• Combines RFID guard monitoring and robust guard locking in one industrial safety device.
• 9750 N locking force provides substantial retention of machine guards and safety doors.
• Working method D keeps the actuator locked when the electromagnet is de-energised.
• Activation mode 2 provides active OS1 and OS2 safety outputs when a compatible actuator is inserted.
• Dedicated O3 signalling output indicates actuator insertion status.
• Dedicated O4 signalling output provides fault information for diagnostics.
• Auxiliary release supports servicing and maintenance requirements.
• IP67 and IP69K protection supports demanding industrial environments.
• Actuator supplied separately, allowing the appropriate coding option to be selected for the machine safety application.

Reliable Guard Locking for Industrial Machinery

Safety switches with guard locking are used where access through a machine guard or safety door must be monitored and controlled. The Pizzato NG 2D1D621A combines RFID actuator detection with a 9750 N locking mechanism, providing robust guard retention while allowing a compatible safety system to electronically monitor the protected access point.

Activation mode 2 allows the OS1 and OS2 safety outputs to become active when a compatible actuator is inserted, while dedicated O3 and O4 outputs provide actuator-status and fault information. Because this model is supplied without an actuator, machine builders can select an appropriate compatible NG series actuator separately to suit the required installation and coding arrangement.

Typical Applications

• Industrial machine guards and safety doors.
• Robotic cells and automated production systems.
• Packaging and processing machinery.
• Automated assembly and manufacturing equipment.
• Machinery requiring high-force guard locking.
• Machine tools and production equipment.
• Material handling and automated manufacturing systems.
• Industrial safety and factory automation applications.
