Why Choose the Pizzato NSG4CE1SMK Safety Interlock Switch?
The Pizzato NSG4CE1SMK is a compact RFID safety interlock switch with solenoid guard locking, designed for industrial machinery that requires reliable door monitoring, actuator recognition, and controlled access to hazardous zones. Manufactured by Pizzato Elettrica, it belongs to the NS series of safety locking devices widely used in machine guarding and OEM automation systems.
This model uses a SMK housing configuration and supports RFID-based actuator recognition for secure guard identification. It is engineered to ensure that machinery cannot operate unless the correct actuator is present and the guard door is properly closed.
The NSG4CE1SMK operates using a G working principle, where the actuator is locked by a de-energised 24 Vdc solenoid. Safety outputs are enabled only when the guard is closed, the actuator is detected, and safe machine conditions are confirmed by the control system. {index=1}

Reliable Machine Guarding for Industrial Systems
The NSG4CE1SMK ensures that machinery remains safely controlled by preventing operation unless the guard is closed and the correct RFID actuator is detected. This improves operator safety and reduces the risk of accidental machine start-up during maintenance or access.
Its safety outputs integrate with PLC-based safety controllers, enabling continuous monitoring of guard status, actuator engagement, and locking condition in automated production environments. {index=2}
