NS D3AZ1SP2-F41 Pizzato NS series safety locking switch, with actuator

Why Choose the Pizzato NS D3AZ1SP2-F41 Safety Locking Switch?

The Pizzato NS D3AZ1SP2-F41 is an advanced RFID safety locking switch with separate actuator designed for reliable monitoring and locking of protective guards, doors and access points on industrial machinery. Part of the Pizzato NS series, it combines contactless RFID actuator recognition with solenoid-operated guard locking and electronic safety outputs in a compact technopolymer housing.

This model uses the D operating principle, meaning the actuator is locked when the electromagnet is de-energised. In Mode 1, the OS safety outputs are active when the protective guard is locked, making the switch suitable for machinery where access must remain prevented until the safety control system permits the guard to be released.

The NS D3AZ1SP2-F41 is supplied with the VN NS-F41 high-level coded actuator, providing enhanced resistance to manipulation or actuator substitution. It also features a front screwdriver-operated auxiliary release, downward-facing connection arrangement and a robust locking mechanism with a holding force of 2,100 N, making it suitable for demanding industrial machine-safety applications.

Reliable RFID Guard Locking for Industrial Machinery

Pizzato NS series switches combine contactless RFID actuator recognition with mechanical guard locking so that a machine safety system can monitor the condition of a protective guard while preventing access during hazardous operating conditions. The high-level coded F41 actuator provides enhanced protection against foreseeable manipulation, while the locking mechanism securely retains the guard until release is permitted.

With its de-energised-electromagnet locking principle, electronic safety outputs, actuator-status signalling and auxiliary release, the NS D3AZ1SP2-F41 provides a comprehensive guard-interlocking solution for modern automated equipment. The technopolymer housing and high ingress protection also make the device well suited to demanding industrial environments.

Typical Applications

• Machine guard and access-door interlocking.
• Automated production and assembly machinery.
• Robotic cells and guarded automation systems.
• Packaging and processing equipment.
• Material handling and conveyor systems.
• Machine tools and manufacturing equipment.
• Industrial machinery requiring high-level coded guard monitoring.
