Why Choose the Pizzato NSD4AZ1DMK Safety Locking Switch?
The Pizzato NSD4AZ1DMK is an advanced RFID safety interlock switch with guard locking designed for secure monitoring of movable guards on industrial machinery. Part of the Pizzato NS Safety Locking Switch series, it combines non-contact RFID actuator detection, electromagnetic guard locking and electronic safety monitoring for integration into modern machine safety systems.
This model uses operating principle D, meaning the actuator is locked when the electromagnet is de-energised. It operates in Mode 1, with the OS safety outputs active when the guard is closed and locked, making it suitable for machinery where hazardous conditions may remain after a stop command and controlled access is required.
The NSD4AZ1DMK provides a maximum 2,100 N holding force, two IS1–IS2 safety inputs and two OS1–OS2 safety outputs. It features a 12-pole M12 connector with lateral connection direction, a front screwdriver-operated auxiliary release and robust IP67 / IP69K protection for demanding industrial installations.
Key Advantages
- Combines RFID guard detection and electromagnetic guard locking in one safety device.
- Principle D locking keeps the actuator locked while the electromagnet is de-energised.
- Maximum 2,100 N holding force provides secure retention of machine guards.
- Mode 1 operation monitors the closed and locked guard condition through the safety outputs.
- Dual IS1–IS2 safety inputs and OS1–OS2 safety outputs support integration into advanced safety circuits.
- Lateral 12-pole M12 connection provides a practical installation option where cable routing space is restricted.
- IP67 / IP69K protection supports dependable operation in demanding industrial environments.

Reliable RFID Guard Locking for Industrial Machinery
Safety interlock switches with guard locking are used where opening a machine guard before hazardous movement has stopped could expose personnel to risk. The Pizzato NSD4AZ1DMK combines RFID-based guard detection with monitored locking, allowing the safety control system to verify that the guard is correctly positioned and securely locked before hazardous machine functions are permitted.
The NS series provides electronic safety inputs and outputs for integration into machine safety architectures. The NSD4AZ1DMK additionally uses a lateral connector arrangement, making it particularly useful where the available mounting or cable-routing space favours a side-facing electrical connection.
Typical Applications
- Industrial machine guard doors and access panels.
- Robotic cells and automated manufacturing equipment.
- Packaging and processing machinery.
- Machines with hazardous residual or run-down movement.
- Automated assembly and production lines.
- Conveyor and material handling systems.
- OEM machinery and integrated industrial safety systems.
