Why Choose the Pizzato STHD420MK-H1T RFID Safety Sensor?
The Pizzato STHD420MK-H1T is a high-performance RFID safety interlock sensor designed for machine guarding, access control, and industrial automation safety applications. Manufactured by Pizzato Elettrica, it ensures reliable non-contact detection of coded actuators, allowing machinery to operate only when protective guards are securely closed.
As part of the Pizzato ST H series, this model is engineered for demanding industrial environments requiring robust door monitoring, safety PLC integration, and compliance with standards such as ISO 14119. It is widely used in automated production systems where high safety integrity and reliable feedback are essential.
The STHD420MK-H1T features high-level coded RFID actuator recognition (H1T), providing enhanced protection against tampering and unauthorized bypass attempts. Its compact technopolymer housing, integrated M12 stainless steel connector, and IP67/IP69K protection ensure reliable operation even in harsh industrial environments such as food, beverage, and heavy manufacturing applications. {index=1}
