Why Choose the Pizzato NSD4AZ1SRK-N111 Safety Interlock Switch?
The Pizzato NSD4AZ1SRK-N111 is a compact RFID safety interlock switch with guard locking and integrated operator control, designed for industrial machine safety applications where reliable access control and local machine command functions are required. Manufactured by Pizzato Elettrica, it ensures that machinery operates only when the protective guard is correctly closed and locked.
This model belongs to the Pizzato NS series multifunction safety switches, combining RFID-coded actuator detection, solenoid-based locking, and an integrated illuminated pushbutton control device in a single industrial-grade housing. It is widely used in OEM machinery and automation systems where simplified wiring and integrated safety functions are required at the point of access.
The NSD4AZ1SRK-N111 operates in a D working method configuration, meaning the actuator is locked using a de-energised solenoid and the safety outputs are enabled only when the guard is correctly closed and secured. {index=1}
Key Advantages
- Integrated RFID safety interlock switch with guard locking.
- Built-in illuminated pushbutton for machine control.
- High-reliability actuator detection and locking feedback.
- Designed for OEM machinery and industrial automation systems.
- Dual M12 connector system for simplified installation.
- Compact design reduces cabinet wiring and external components.
Key Features
- Pizzato NS series safety interlock switch.
- Model: NSD4AZ1SRK-N111.
- RFID-coded actuator detection system.
- Integrated control device:
- White illuminated pushbutton (1NO, spring-return)
- 2 safety inputs (IS1–IS2) and 2 safety outputs (OS1–OS2).
- 2 solenoid activation inputs (IE1–IE2).
- 1 programming/reset input (I3).
- Signal outputs: O3 (actuator inserted), O4 (actuator locked).
- Dual M12 connectors (12-pole + 5-pole axial configuration).
Integrated Machine Safety with Local Control
The Pizzato NSD4AZ1SRK-N111 combines guard locking and local machine control in a single device. The RFID system ensures correct actuator recognition, while the solenoid locking mechanism prevents access during hazardous machine cycles.
The integrated illuminated pushbutton allows operators to perform local machine commands directly at the safety gate, reducing the need for separate control panels and improving operational efficiency in automated systems.
Typical Applications
- Automated production and assembly systems.
- Industrial robotic safety enclosures.
- Packaging and processing machinery.
- Machine tools with safety door interlocks.
- OEM machine building and integration systems.
- Material handling and conveyor safety systems.
