Why Choose the Pizzato NSD4CE1SB2-F41 Safety Interlock Switch?
The Pizzato NSD4CE1SB2-F41 is a high-performance RFID safety interlock switch with solenoid guard locking, designed for industrial machine safety applications requiring secure access control, reliable actuator recognition, and strong tamper resistance. Manufactured by Pizzato Elettrica, it ensures machinery remains safely locked until hazardous conditions are fully resolved.
This model belongs to the Pizzato NS series of safety locking switches featuring high-coded RFID actuator technology (F41) combined with integrated solenoid locking. It is widely used in OEM machinery, robotic safety systems, and automated production lines where high integrity guarding and dependable performance are required.
The NSD4CE1SB2-F41 operates in an S working method configuration, meaning the actuator is locked using a de-energised 24 Vdc solenoid. Safety outputs are enabled only when the guard is closed, correctly aligned, and the RFID system confirms the presence of the correct high-coded actuator. {index=1}
