NS D4AZ1SRK-N114 Pizzato NS series safety switch with lock and integrated control devices

Why Choose the Pizzato NSD4AZ1SRK-N114 Safety Interlock Switch?

The Pizzato NSD4AZ1SRK-N114 is a high-performance RFID safety interlock switch with integrated control devices and guard locking, designed for industrial machine safety systems that require both secure access control and local operator interface functionality. Manufactured by Pizzato Elettrica, it provides reliable protection by ensuring machinery remains locked until all safety conditions are satisfied.

This model belongs to the Pizzato NS series multifunction safety switches, combining RFID-coded actuator recognition, solenoid locking technology, and an integrated dual-control operator panel in a compact industrial housing. It is widely used in OEM machinery, robotics, and automated production systems where safety interlocking and operator commands must be combined at the guard position.

The NSD4AZ1SRK-N114 operates in a D working method configuration, meaning the actuator is locked with a de-energised solenoid and the safety outputs are enabled only when the guard is correctly closed and secured. It is part of the NS SRK integrated control family designed to reduce external wiring and simplify machine-side control architecture. {index=1}

Integrated Machine Safety with Operator Control

The Pizzato NSD4AZ1SRK-N114 integrates RFID safety interlocking with local operator control at the machine guard. This allows operators to manage key machine functions directly at the access point while maintaining high safety integrity.

The solenoid locking system ensures the guard cannot be opened during hazardous machine states, while the RFID actuator guarantees correct alignment and identification. The integrated pushbutton and emergency stop provide immediate local control for operational efficiency and safety response.

Typical Applications

• Industrial robotic safety cells.
• Automated production and assembly systems.
• Packaging and processing machinery.
• Machine tools with integrated safety door controls.
• OEM machine building and integration systems.
• Material handling and conveyor safety systems.
