NS D3AZ1SQK-F41 Pizzato NS series safety locking switch, with actuator

Why Choose the Pizzato NS D3AZ1SQK-F41 Safety Locking Switch?

The Pizzato NS D3AZ1SQK-F41 is a robust RFID safety locking switch with separate actuator, designed for reliable monitoring and locking of machine guards, access doors and hazardous areas in industrial automation systems. As part of the advanced Pizzato NS safety locking switch series, it combines non-contact RFID actuator detection, electronic safety monitoring and electromagnetic guard locking in a durable technopolymer housing.

The D working method keeps the actuator locked when the solenoid is de-energised, providing guard locking that remains secured following loss of electrical power. The supplied VN NS-F41 high-coded RFID actuator provides a high coding level, meaning the switch recognises its associated F41 actuator and helps prevent manipulation through actuator substitution. A front screwdriver-operated auxiliary release provides convenient manual unlocking when required during servicing or maintenance.

The NS D3AZ1SQK-F41 uses Mode 1, with the safety outputs active when the protective guard is locked. It provides two safety inputs, two safety outputs, actuator-inserted and actuator-locked signalling outputs, two solenoid activation inputs and a reset input. The M12 8-pole connector supports series connection using Y connectors, making the switch suitable for distributed machine safety installations.

Reliable Machine Guarding and Safety Control

The Pizzato NS series combines RFID actuator recognition with electronic safety monitoring and electromagnetic guard locking to provide a dependable interface between machine guards and safety control systems. The non-contact RFID technology detects the high-coded F41 actuator while the electronic safety outputs communicate the guard status to a suitable safety PLC or safety module.

The NS D3AZ1SQK-F41 uses the D working method, meaning the actuator remains locked when the solenoid is de-energised. Its Mode 1 configuration activates the OS1 and OS2 safety outputs when the protective guard is locked, while O3 and O4 provide separate actuator-inserted and actuator-locked status signals. The M12 8-pole connection permits series connection using Y connectors, helping simplify distributed safety installations.

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.
• Distributed machine safety systems using series-connected safety devices.
