NS G3AZ1SMK-F40 Pizzato NS series safety locking switch, with actuator

Why Choose the Pizzato NSG3AZ1SMK-F40 Safety Interlock Switch?

The Pizzato NSG3AZ1SMK-F40 is a compact RFID safety interlock switch with solenoid guard locking, designed for industrial machine safety applications where reliable access control, actuator detection, and cost-efficient safety performance are required. Manufactured by Pizzato Elettrica, it ensures that hazardous machinery remains safely locked until safe operating conditions are restored.

This model belongs to the Pizzato NS series safety locking switches with RFID-coded actuator recognition and integrated safety outputs. It is widely used in OEM machinery, packaging systems, and automation equipment where dependable guard monitoring and standard-level coding protection are required.

The NSG3AZ1SMK-F40 operates in a G working method configuration, meaning the actuator is locked with a de-energised 24 Vdc solenoid and safety outputs are enabled only when the guard is correctly closed. The F40 actuator provides a low-coded universal keying solution, ideal for standard industrial applications where flexibility and interchangeability are important. {index=1}

Reliable Guard Locking for Industrial Systems

The Pizzato NSG3AZ1SMK-F40 is designed to prevent access to hazardous machine areas by ensuring the guard remains locked until safe conditions are confirmed. Its RFID detection system verifies actuator presence and position, reducing the risk of accidental or unintended machine access.

The integrated safety outputs allow direct connection to safety PLCs or controllers, enabling continuous monitoring of guard status, actuator insertion, and lock condition in automated production environments.

Typical Applications

• Industrial automation systems.
• Packaging and processing machinery.
• Robotic safety enclosures.
• Machine tools with standard safety guarding.
• OEM equipment manufacturing.
• Material handling and conveyor systems.
