NS D4AZ1SRK-N110 Pizzato NS series safety switch with lock and integrated control devices

Why Choose the Pizzato NSD4AZ1SRK-N110 Safety Interlock Switch?

The Pizzato NSD4AZ1SRK-N110 is a robust RFID safety interlock switch with integrated control devices and guard locking, designed for industrial machine safety applications where both access control and operator intervention are required at the same point. Manufactured by Pizzato Elettrica, it ensures that machinery remains safely locked until all safety conditions are met.

This model belongs to the Pizzato NS series multifunction safety switches, combining RFID-coded actuator detection, solenoid-based guard locking, and a built-in emergency stop control device in a compact industrial housing. It is widely used in OEM machinery and automation systems where safe access and machine control must be tightly integrated.

The NSD4AZ1SRK-N110 operates in a D working method configuration, meaning the actuator is locked using a de-energised solenoid and the safety outputs become active only when the guard is correctly closed and secured. {index=1}

Integrated Machine Safety and Emergency Control

The Pizzato NSD4AZ1SRK-N110 combines guard locking and emergency stop functionality in a single device, allowing operators to safely stop machinery directly at the access point. This reduces the need for separate control stations and improves reaction time during hazardous situations.

The RFID system ensures that only correctly positioned actuators allow operation, while the solenoid locking mechanism prevents access during dangerous machine cycles. The integrated emergency stop adds a direct safety layer for immediate machine shutdown.

Typical Applications

• Industrial robotic safety cells.
• Automated production lines.
• Packaging and processing machinery.
• Machine tools with safety door interlocks.
• OEM automation system integration.
• Material handling and conveyor systems.
