Why Choose the Pizzato STHD420N2-H1T RFID Safety Sensor?
The Pizzato STHD420N2-H1T is a high-reliability RFID safety interlock sensor designed for machine guarding, access control, and industrial automation safety applications. Manufactured by Pizzato Elettrica, it provides secure non-contact detection of coded actuators, ensuring machinery operates only when protective guards are correctly closed.
As part of the Pizzato ST H series, this model is engineered for demanding industrial environments requiring robust safety door monitoring, safety PLC integration, and compliance with standards such as ISO 14119. It is widely used in OEM machinery and automated production systems where high safety integrity and reliable feedback are essential.
The STHD420N2-H1T features high-level coded RFID actuator recognition (H1T variant), offering strong protection against tampering and unauthorized bypass attempts. Its compact technopolymer housing and IP67/IP69K protection ensure reliable operation in harsh industrial environments such as packaging, food processing, and automated manufacturing systems. {index=1}
