Why Choose the Pizzato NSD4AZ1SMK-E37 Safety Interlock Switch?
The Pizzato NSD4AZ1SMK-E37 is a high-performance RFID safety interlock switch with solenoid guard locking, designed for industrial machine safety applications where secure access control, high actuator retention force, and reliable status monitoring are essential. Manufactured by Pizzato Elettrica, it ensures that hazardous machinery remains safely locked until all safety conditions are satisfied.
This model belongs to the Pizzato NS series of safety interlock switches with coded actuator recognition and integrated safety outputs. It is widely used in OEM machinery, robotics, and automated production systems where robust guarding and compliance with modern safety standards are required.
The NSD4AZ1SMK-E37 operates in a D working method configuration, meaning the actuator is locked using a de-energised solenoid and safety outputs are enabled only when the guard is correctly closed and secured. The “E37” variant provides a defined actuator extraction force configuration, improving controlled release behavior in safety-critical installations. {index=1}
