NS G3AZ1SMK-F41 Pizzato NS series safety locking switch, with actuator

Why Choose the Pizzato NS G3AZ1SMK-F41 Safety Locking Switch?

The Pizzato NS G3AZ1SMK-F41 is an RFID safety interlock switch with guard locking designed for monitoring movable guards and controlling access to hazardous areas of industrial machinery. Part of the Pizzato NS Safety Interlock Switches range, it combines electronic RFID actuator detection, safety-related outputs and robust solenoid locking in a compact technopolymer housing.

This configuration is supplied with the VN NS-F41 high-level coded RFID actuator. The F41 actuator is individually coded to provide a high coding level according to EN ISO 14119, helping reduce the possibility of defeating the safety function through unauthorised actuator substitution. The AZ configuration incorporates a front screwdriver-operated auxiliary release for authorised manual unlocking during maintenance or servicing.

The G3 configuration uses the NS Mode 2 safety architecture, with OS1–OS2 safety outputs active when the actuator is inserted. Electrical connection is provided by the SMK axial M12 12-pole connector. Together with a maximum holding force of 2,100 N and robust environmental protection, the NS G3AZ1SMK-F41 provides a versatile solution for modern machine guarding and industrial automation.

High-Level Coded RFID Guard Monitoring and Locking

The Pizzato NS platform is designed for safety-related monitoring of movable machine guards where electronic actuator recognition and controlled mechanical retention are required. RFID technology allows the safety switch to recognise its coded actuator, while electronic safety and signalling outputs communicate guard conditions to the machine safety system.

The F41 high-level coded actuator provides individual coding for enhanced resistance to actuator substitution, while the AZ front screwdriver release provides a practical auxiliary unlocking method for authorised personnel. Combined with Mode 2 operation, an axial M12 connection and a maximum 2,100 N holding force, the NS G3AZ1SMK-F41 is well suited to sophisticated automated machinery.

Typical Applications

• Automated machine guard doors.
• Robotic cells and manufacturing systems.
• Packaging and processing machinery.
• Automated assembly equipment.
• Machining centres and guarded machine tools.
• Conveyor and material handling systems.
• Industrial production cells with controlled access.
• Safety systems requiring high-level coded RFID guard monitoring.
