Why Choose the Pizzato ST HE421MP-H1TF ST H Series Safety Sensor?
The Pizzato ST HE421MP-H1TF is an advanced RFID electronic safety interlock sensor designed for reliable non-contact monitoring of guards, doors and access points on industrial machinery. As part of the Pizzato ST H RFID Safety Sensor Series, it combines coded RFID actuator detection with electronic safety inputs and outputs to provide dependable machine guarding without the mechanical wear associated with conventional contact-based safety switches.
Operating from a 24 V DC supply, the ST HE421MP-H1TF provides two safety inputs IS1–IS2 and two safety outputs OS1–OS2, together with signalling functionality for integration into modern safety and automation architectures. The H1 configuration uses a high-level coded RFID actuator, helping protect the safety function against substitution with an incorrect actuator.
The ST HE421MP-H1TF features an actuation distance of approximately 11 mm and an integrated M12 technopolymer connector for straightforward machine wiring and replacement. Its robust ST H series construction and IP67 / IP69K protection make it particularly suitable for demanding industrial environments where reliable guard monitoring and convenient installation are required.
