ST HD510MK-H1T Pizzato ST H series safety sensor

Why Choose the Pizzato STHD510MK-H1T Safety Interlock Sensor?

The Pizzato STHD510MK-H1T is a high-reliability RFID safety interlock sensor designed for machine guarding, access control, and industrial automation safety systems. As part of the advanced Pizzato ST H series RFID safety sensor platform, it ensures secure non-contact monitoring of safety doors and protective guards in demanding industrial environments.

This model uses high-level coded RFID actuator recognition (H1T logic) to ensure that only a correctly paired actuator can enable machine operation, improving protection against tampering and unauthorized bypass attempts. It is widely used in OEM machinery, robotics, packaging systems, and automated production lines where functional safety compliance with PL e (ISO 13849-1) and SIL 3 (IEC 61508) is required.

The STHD510MK-H1T features a compact technopolymer housing with integrated M12 connector (MK version), designed for fast installation and reliable wiring in industrial control panels. Its non-contact RFID sensing system eliminates mechanical wear, improving durability and ensuring long service life in high-cycle automation environments. {index=1}
