NS D4AZ1SM0.2 Pizzato NS series safety locking switch

Why Choose the Pizzato NSD4AZ1SM0.2 Safety Locking Switch?

The Pizzato NSD4AZ1SM0.2 is a robust RFID safety interlock switch with electromagnetic guard locking designed for monitoring and securing movable guards on industrial machinery. Part of the Pizzato NS Safety Locking Switch series, it combines contactless RFID actuator detection, monitored guard locking and electronic safety outputs for integration into modern machine safety circuits.

This model uses operating principle D, meaning the actuator is locked when the 24 V DC electromagnet is de-energised. It operates in Mode 1, with the OS1 and OS2 safety outputs active when the actuator is inserted and locked, allowing the safety control system to verify a secure guard condition before hazardous machine functions are enabled.

The NSD4AZ1SM0.2 provides a maximum 2,100 N actuator holding force and features a front screwdriver-operated auxiliary release. Its axial electrical connection uses a 0.2 m cable with an M12 connector, while the technopolymer housing and IP67 / IP69K protection provide durability for demanding industrial installations.

Key Advantages

• Combines RFID guard detection and electromagnetic guard locking in one safety device.
• Principle D locking retains the actuator when the 24 V DC electromagnet is de-energised.
• Maximum 2,100 N holding force provides secure retention of movable machine guards.

Reliable RFID Guard Locking for Industrial Machinery

Safety interlock switches with guard locking are used where access to hazardous machinery must remain restricted until a safe condition has been established. The Pizzato NSD4AZ1SM0.2 combines contactless RFID detection with monitored electromagnetic locking, allowing a safety control system to verify that a compatible actuator is correctly inserted and locked before hazardous machine functions are permitted.

The NS series provides redundant electronic safety inputs and outputs and can be incorporated into safety architectures up to PL e and SIL 3 when correctly designed and validated. Its high holding force, robust environmental protection and compact axial cable-and-connector arrangement make the NSD4AZ1SM0.2 suitable for a wide variety of OEM machinery and automated production equipment.

Typical Applications

• Industrial machine guard doors and access panels.
• Robotic cells and automated manufacturing systems.
• Packaging and processing machinery.
• Machines with hazardous residual or run-down movement.
• Automated assembly and production lines.
• Conveyor and material handling equipment.
• OEM machinery and integrated industrial safety systems.
