Why Choose the Pizzato NSD4CE1SMK Safety Interlock Switch?
The Pizzato NSD4CE1SMK is a high-performance RFID safety interlock switch with solenoid guard locking, designed for industrial machinery that requires secure access control, reliable actuator detection, and high-integrity safety monitoring. Manufactured by Pizzato Elettrica, it is part of the advanced NS series safety locking devices used widely in OEM automation systems and machine guarding applications.
This model belongs to the NS series “SMK” configuration, which combines a compact safety interlock body with RFID-coded actuator recognition and robust mechanical locking. It is engineered to prevent access to hazardous machine areas until all dangerous motion has stopped and safety conditions are confirmed.
The NSD4CE1SMK operates with a solenoid-controlled locking mechanism and RFID actuator verification. Safety outputs are enabled only when the guard is closed, the actuator is correctly detected, and the system confirms a safe machine state. {index=1}
Key Advantages
- High-security RFID actuator recognition system.
