Why Choose the Pizzato NSG3CE1SMK-F41 Safety Interlock Switch?
The Pizzato NSG3CE1SMK-F41 is a compact RFID safety interlock switch with solenoid guard locking, engineered for industrial machinery requiring reliable access control, actuator recognition, and high-integrity machine safety. Manufactured by Pizzato Elettrica, it is part of the NS series safety locking devices widely used in OEM automation and industrial guarding applications.
This model belongs to the NS “G3” SMK configuration with a high-coded RFID actuator (F41 level), ensuring a unique one-to-one actuator match for enhanced tamper resistance. It is designed for machine guards where safety, reliability, and compact installation are essential.
The NSG3CE1SMK-F41 operates using a G working principle, where the actuator is held by a de-energised 24 Vdc solenoid. Safety outputs are enabled only when the guard is closed, the correct actuator is detected, and safe machine conditions are confirmed. {index=1}

High-Integrity Machine Protection
The NSG3CE1SMK-F41 ensures that machinery remains safely controlled by preventing operation unless the correct RFID-coded actuator is present and the guard is properly closed. The high coding level significantly reduces risks of bypass or unauthorized substitution.
Its safety outputs integrate with PLC safety systems, enabling continuous monitoring of guard status, actuator presence, and locking condition in automated industrial environments. {index=2}
