Why Choose the Pizzato NS G5AZ1SMK Safety Locking Switch?
The Pizzato NS G5AZ1SMK is an RFID safety interlock switch with electromagnetic guard locking designed for monitoring and controlling movable guards on industrial machinery. Part of the Pizzato NS series, it combines non-contact RFID actuator recognition, secure mechanical guard retention and redundant electronic safety outputs within a robust technopolymer housing.
This configuration uses Principle G, meaning the actuator is locked while the electromagnet is de-energised, and operates in Mode 2 with the OS1 and OS2 safety outputs active when the guard is closed. It provides two safety inputs IS1–IS2, two safety outputs OS1–OS2, O3 and O4 signalling outputs, two electromagnet activation inputs IE1–IE2 and an I3 programming/reset input.
The NS G5AZ1SMK provides a maximum actuator holding force of 2100 N, a front screwdriver-operated auxiliary release and a bottom-mounted M12 12-pole connector. The base NS G5AZ1SMK is supplied without an actuator, allowing the appropriate compatible Pizzato NS RFID actuator to be selected separately for the required coding level.
Key Advantages
- Combines RFID guard monitoring and electromagnetic guard locking in one safety device.
- Principle G de-energised-solenoid locking retains the actuator while the electromagnet is not energised.
- Provides up to 2100 N maximum actuator holding force.
- Two safety inputs and two redundant safety outputs support integration with compatible safety controllers.
- Separate O3 and O4 signalling outputs communicate actuator-inserted and actuator-locked status.
- Front screwdriver-operated auxiliary release provides manual unlocking when required.
- M12 12-pole connector provides convenient plug-in electrical connection.
- IP67 / IP69K protection supports demanding industrial environments.
- Actuator supplied separately, allowing the appropriate compatible RFID coding option to be selected.

RFID Guard Monitoring with De-Energised-Solenoid Locking
The Pizzato NS series is designed for industrial machinery where movable guards must be electronically monitored and access must remain controlled under defined machine conditions. RFID technology provides non-contact coded actuator recognition, while redundant safety outputs and dedicated status signals allow compatible safety-control equipment to supervise the guard and locking conditions.
With its Principle G operating method, the NS G5AZ1SMK retains the actuator while the locking electromagnet is de-energised. Combined with a maximum actuator holding force of 2100 N, robust environmental protection and a manual auxiliary release, this configuration provides a versatile basis for machine safety interlocking systems where the required RFID actuator is selected separately.
Typical Applications
- Machine safety doors and movable guards.
- Robotic cells and automated manufacturing systems.
- Machinery requiring controlled access to hazardous areas.
- Machinery with hazardous run-down periods.
- Packaging and processing equipment.
- Assembly and production lines.
- Conveyor and material handling systems.
- Machining centres and industrial production equipment.
- OEM machinery requiring RFID safety interlocking and guard locking.
