Why Choose the Pizzato NS D4AZ1DPK Safety Locking Switch?
The Pizzato NS D4AZ1DPK is an advanced RFID safety locking switch with electromagnet designed for reliable monitoring and locking of protective guards on industrial machinery and automated equipment. As part of the Pizzato NS safety locking switch series, it combines contactless RFID actuator detection with electromagnetic guard locking to provide a high level of machine safety in a compact technopolymer housing.
The NS D4AZ1DPK uses RFID technology with a digitally coded actuator, allowing the switch to identify the associated actuator without conventional mechanical contacts. The NS series is designed to achieve SIL 3 and Performance Level e with a single device, while also supporting series connection of up to 32 devices for suitable safety applications.
This version is supplied without an actuator, allowing the appropriate NS-series coded actuator to be selected separately for the machine guarding application. The switch provides a 2-channel safety interface, auxiliary status signalling and electromagnetic control inputs, with an M12 8-pole connector for stand-alone connections.

Reliable Safety Control for Industrial Machinery
Safety locking switches such as the Pizzato NS D4AZ1DPK form an important part of modern machine safeguarding systems. RFID technology enables contactless identification of the coded actuator, allowing the safety system to determine whether the protective guard is correctly positioned without relying on traditional mechanical switching contacts.
The electromagnetic locking mechanism helps control access to hazardous areas, while the switch provides redundant safety inputs and outputs together with dedicated status and electromagnet control signals. The NS series can also be connected in series, with up to 32 devices supported for applications requiring multiple monitored guards.
Typical Applications
- Industrial machine guarding and protective doors.
- Automated production and assembly machinery.
- Robotic cells and automated manufacturing systems.
- Packaging and processing equipment.
- Machine tools and production machinery.
- Safety circuits requiring coded RFID guard monitoring.
- Applications requiring electromagnetic protective guard locking.
