NG 2D1D421A-F31 Pizzato NG series safety switch with lock, with actuator

Why Choose the Pizzato NG 2D1D421A-F31 Safety Switch with Lock?

The Pizzato NG 2D1D421A-F31 is an NG series RFID safety switch with guard locking, designed for monitoring and securing movable guards, doors and access points on industrial machinery. It combines coded electronic actuator detection, safety outputs and high-force guard locking in a robust metal housing, without integrated control devices on the cover.

This configuration uses Pizzato's D working method, in which the actuator is locked with the solenoid de-energised. It features two IS1-IS2 safety inputs, two OS1-OS2 safety outputs and dedicated O3 and O4 signalling outputs for actuator-inserted and actuator-locked status.

The NG 2D1D421A-F31 uses safety-output activation mode 2, meaning the OS1-OS2 safety outputs are active when the actuator is inserted. It is supplied complete with the VN NG-F31 high-coding-level RFID actuator and provides a maximum holding force of 9750 N, making it suitable for demanding industrial guard-locking applications.

Key Advantages

• RFID-coded guard monitoring provides non-contact electronic actuator recognition.
• Supplied complete with the VN NG-F31 high-coding-level actuator.
• D working method locks the actuator with the solenoid de-energised.
• Maximum 9750 N holding force provides robust guard retention.
• Mode 2 safety-output activation makes OS1-OS2 active when the actuator is inserted.
• Separate O3 and O4 outputs provide actuator-inserted and actuator-locked status.
• IP67 and IP69K protection supports use in demanding industrial environments.
• Metal housing, rotating head and three M20 × 1.5 conduit entries provide flexible machine installation.

RFID Guard Monitoring with Mode 2 Safety Outputs

The Pizzato NG series combines RFID-based actuator recognition with electromechanical guard locking for safety-related machine guarding. The high-coding-level VN NG-F31 actuator is individually coded and must be associated with the safety switch, helping provide a high level of protection against actuator substitution while retaining the ability to reprogramme the switch for another F31 actuator when required.

A distinguishing feature of the NG 2D1D421A-F31 is its Mode 2 safety-output logic. The OS1-OS2 safety outputs become active when the actuator is inserted, while the separate O4 signalling output communicates the locked condition. This allows the machine safety architecture to distinguish guard insertion from guard-locking status according to the requirements of the application.
