Why Choose the Pizzato STHE420H2-H1TF RFID Safety Sensor?
The Pizzato STHE420H2-H1TF 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 advanced Pizzato ST H series, this model is widely used in OEM machinery and industrial automation systems requiring dependable safety door monitoring, integration with safety PLCs, and compliance with ISO 14119. It is engineered for environments where robust mechanical installation and high functional safety are both required.
The STHE420H2-H1TF features high-level coded RFID actuator recognition (H1TF variant), providing strong protection against tampering and unauthorized bypass attempts. The H2 housing version offers a rugged mounting format for flexible installation, while IP67/IP69K protection ensures reliable operation in harsh industrial environments such as packaging, food processing, and heavy-duty automation systems. {index=1}
