ST HD421H2-H1T Pizzato ST H series safety sensor

Product Overview

The Pizzato ST HD421H2-H1T is an electronic RFID safety sensor from the Pizzato ST H series, designed for non-contact monitoring of machine guards, safety doors and protective access points. The H1T configuration uses a high-level coded RFID actuator, supporting industrial safety applications where enhanced protection against actuator substitution is required.

The ST HD421H2-H1T belongs to Pizzato's compact ST H safety-sensor family and combines coded non-contact detection with electronic safety outputs for integration into machine safety circuits. The H2 connection configuration provides a pre-wired solution for straightforward installation on industrial machinery.

Key Advantages

• RFID non-contact sensing: Electronic actuator detection avoids the mechanical engagement required by traditional tongue-operated interlocks.
• High-level coding: The H1T actuator configuration provides high-level coded identification for enhanced protection against actuator substitution.
• Machine-safety integration: Designed specifically for monitoring movable guards, doors and protective access points.
• Reduced mechanical wear: Non-contact operation eliminates mechanical switching contact between the sensor and actuator.
• Compact ST H format: Suitable for installations where a compact electronic safety sensor is preferred.
• Industrial construction: Designed for reliable operation in industrial automation and machine-guarding systems.
