Why Choose the Pizzato NSD4AZ1STK-N105 Safety Interlock Switch?
The Pizzato NSD4AZ1STK-N105 is an NS series RFID safety switch with guard locking and integrated control devices for monitoring and controlling access to hazardous areas of industrial machinery. It combines contactless RFID guard detection, electromagnetic guard locking and operator-control functionality within a single integrated assembly.
The NSD4AZ1STK-N105 belongs to Pizzato's NS family of electronic safety switches, designed to provide reliable monitoring of movable guards while retaining the guard when required by the machine safety system. Its D working principle provides locking with the electromagnet de-energised, making it suitable for applications where controlled guard release is required after hazardous machine conditions have ceased.
Electronic safety inputs and outputs enable straightforward integration with suitable safety controllers, while dedicated signalling outputs provide information about actuator presence and locking status. The integrated control-device section places operator functions directly alongside the guard interlock, helping machine builders create compact and practical guarded-access stations.
Key Advantages
- Combines RFID safety monitoring, guard locking and integrated operator controls in one device.
- D working principle retains the actuator while the electromagnet is de-energised.
- Contactless RFID technology provides reliable electronic monitoring of the guard actuator.
- Dual safety inputs and outputs support integration with modern machine safety systems.
- Dedicated signalling outputs provide actuator and locking status information.
- Integrated control devices reduce the need for a separate operator-control station beside the guard.
- Part of the established Pizzato NS electronic safety switch platform.

Integrated RFID Guard Locking and Machine Control
Guard-locking safety switches are used where access to hazardous machine areas must remain restricted until a safe condition has been established. The Pizzato NSD4AZ1STK-N105 combines electronic RFID actuator detection with monitored electromagnetic locking, allowing the machine safety system to supervise both guard position and locking status.
Integrating operator control devices into the same assembly provides a convenient interface directly beside the protected access point. This arrangement can reduce separate components and simplify machine layouts while retaining the electronic safety monitoring required for sophisticated automated equipment and production machinery.
Typical Applications
- Industrial machine guard doors and access points.
- Robotic cells and automated manufacturing systems.
- Packaging and processing machinery.
- Automated assembly and production equipment.
- Machines requiring controlled access after hazardous movement has stopped.
- Conveyor and material handling installations.
- OEM machinery requiring integrated guard locking and operator controls.
