Why Choose the Pizzato NSD4CE1SMK-F41 Safety Interlock Switch?
The Pizzato NSD4CE1SMK-F41 is a high-security RFID safety interlock switch with solenoid guard locking, designed for industrial machinery requiring strong tamper resistance, reliable actuator identification, and robust safety performance. Manufactured by Pizzato Elettrica, it belongs to the advanced NS series safety locking switches used in OEM automation and machine guarding systems.
This model features a high-coded RFID actuator (F41 level) combined with a compact SMK housing configuration. It ensures that access to hazardous machine areas is only permitted when the actuator is correctly recognised and all safety conditions are met.
The NSD4CE1SMK-F41 operates using a D 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 the system confirms a safe machine state. {index=1}

Reliable Machine Guarding for Industrial Systems
The NSD4CE1SMK-F41 is designed to prevent access to dangerous machinery until all hazardous movement has stopped. The high-coded RFID system significantly reduces the risk of bypass or tampering compared to standard mechanical safety switches.
Its safety outputs integrate with PLC safety controllers, enabling continuous monitoring of guard position, actuator presence, and lock status in automated production environments. {index=2}
