NS G4AZ1DPK-F40 Pizzato NS series safety locking switch, with actuator

Why Choose the Pizzato NS G4AZ1DPK-F40 Safety Locking Switch?

The Pizzato NS G4AZ1DPK-F40 is an advanced RFID safety interlock switch with electromagnetic guard locking designed for monitoring and controlling access to hazardous areas of industrial machinery. Part of the Pizzato NS series, it combines non-contact RFID actuator detection, robust guard retention and redundant electronic safety outputs within a durable technopolymer housing.

This configuration uses Principle G, meaning the actuator is locked while the electromagnet is de-energised. It operates in Mode 2, with the OS safety outputs active when the guard is closed, and provides two safety inputs IS1–IS2, two safety outputs OS1–OS2, separate O3 and O4 signalling outputs, two electromagnet activation inputs IE1–IE2 and an I3 programming/reset input.

The NS G4AZ1DPK-F40 is supplied with the VN NS-F40 low-level coded RFID actuator and provides a maximum actuator holding force of 2100 N. A front screwdriver-operated auxiliary release, M12 12-pole connector and IP67 / IP69K environmental protection make it a versatile solution for industrial safety doors, movable guards and automated machinery.

Key Advantages

• Combines RFID guard monitoring and electromagnetic guard locking in one safety device.
• Supplied complete with a VN NS-F40 low-level coded RFID actuator.
• Principle G de-energised-solenoid locking retains the actuator when the electromagnet is not energised.

Reliable RFID Guard Monitoring and De-Energised Locking

The Pizzato NS series is designed for machinery where hazardous conditions may continue after a stop command or where access to particular guards must only be permitted under controlled conditions. RFID technology enables non-contact detection of the coded actuator, while dedicated safety and signalling outputs allow the machine control system to monitor guard and lock conditions.

With Principle G operation, the NS G4AZ1DPK-F40 retains the actuator while the locking electromagnet is de-energised. Combined with a maximum 2100 N actuator holding force and the supplied F40 coded actuator, this configuration provides robust guard retention and electronic monitoring for demanding machine-safety applications.

Typical Applications

• Machine safety doors and movable guards.
• Robotic cells and automated production systems.
• Machinery with hazardous run-down periods.
• Packaging and processing machinery.
• Assembly and manufacturing lines.
• Conveyor and material handling systems.
• Machining centres and production equipment.
• OEM machinery requiring RFID guard monitoring and de-energised-solenoid locking.
