Why Choose the Pizzato NS D4AZ1DA3 Safety Locking Switch?
The Pizzato NS D4AZ1DA3 is a robust RFID safety locking switch without actuator, designed for reliable monitoring and locking of machine guards, access doors and hazardous areas in industrial automation systems. As part of the advanced Pizzato NS safety locking switch series, it combines non-contact RFID actuator detection, electronic safety monitoring and electromagnetic guard locking in a durable technopolymer housing.
The D working principle keeps the actuator locked when the electromagnetic solenoid is de-energised, helping maintain guard locking following loss of electrical power. The switch is supplied without an actuator, allowing the appropriate compatible NS-series RFID actuator to be selected separately. A front screwdriver-operated auxiliary release provides a practical manual release facility for authorised servicing and maintenance.
The NS D4AZ1DA3 uses Mode 1, with the safety outputs active when the protective guard is locked. It provides two safety inputs, two safety outputs, actuator-inserted and actuator-locked signalling outputs, two electromagnetic activation inputs and a programming/reset input. Its pre-wired cable connection and robust enclosure make it suitable for integration into industrial machine safety systems.

Reliable Machine Guarding and Safety Control
The Pizzato NS series combines RFID actuator recognition with electronic safety monitoring and electromagnetic guard locking to provide a dependable interface between machine guards and safety control systems. The non-contact RFID technology detects a compatible NS-series actuator while the electronic safety outputs communicate the guard status to an appropriate safety PLC or safety module.
The NS D4AZ1DA3 uses the D working principle, meaning the actuator remains locked when the electromagnetic solenoid is de-energised. Its Mode 1 configuration activates the OS1 and OS2 safety outputs when the protective guard is locked, while O3 and O4 provide separate actuator-inserted and actuator-locked status signals. The pre-wired cable connection provides a straightforward connection arrangement for suitable machine safety circuits.
Typical Applications
- Machine guarding and safety access doors.
