Why Choose the Pizzato NS D5ST1DMK-F41 Safety Locking Switch?
The Pizzato NS D5ST1DMK-F41 is an advanced RFID safety locking switch with high-level coded actuator designed for monitoring and locking guards, doors and access points on industrial machinery. As part of the Pizzato NS series RFID safety switches with lock, it combines electronic actuator detection, monitored guard locking and diagnostic functionality in a robust technopolymer housing.
This version uses the D operating principle, keeping the actuator locked while the solenoid is de-energised. It is supplied complete with the VN NS-F41 high-level coded RFID actuator and incorporates a front key-operated auxiliary release. Mode 1 operation means the OS1 and OS2 safety outputs become active when the actuator is inserted and the guard is locked, making the switch suitable for machinery where access must remain prevented until a safe condition has been established.
The NS D5ST1DMK-F41 incorporates EDM feedback monitoring and provides two safety inputs, two safety outputs, actuator and lock signalling outputs, solenoid activation inputs and programming/reset functionality. A 12-pole M12 lateral orientable connector simplifies integration into machine wiring, while IP67 and IP69K protection supports installation in demanding industrial environments.

Reliable Guard Locking for Industrial Machinery
Safety locking switches are used where opening a machine guard before hazardous movement has stopped could expose personnel to risk. The Pizzato NS series combines RFID actuator recognition with monitored locking, allowing the machine safety system to verify both the presence of the actuator and the locked condition of the guard.
The high-level coded VN NS-F41 actuator is individually encoded and associated with its safety switch, helping reduce the possibility of bypassing the protective device with another actuator. Together with the de-energise-to-lock operating principle, EDM monitoring, safety inputs and outputs, and clear status signalling, the NS D5ST1DMK-F41 provides a comprehensive interface for modern machine safety systems.
Typical Applications
- Machine guard doors requiring monitored locking.
- Automated production and assembly machinery.
- Packaging and processing equipment.
- Robotic cells and restricted machine access points.
- Conveyor and material handling systems.
- Machining centres and automated manufacturing equipment.
- Industrial safety systems requiring high-level coded RFID interlocking.
