Why Choose the Pizzato ST HE420N2-H0TE ST H Series Safety Sensor?
The Pizzato ST HE420N2-H0TE is a robust RFID non-contact safety sensor designed for reliable monitoring of guards, doors and access points on industrial machinery. As part of the advanced Pizzato ST H series, it combines coded RFID detection with electronic safety outputs to provide dependable guard position monitoring without the mechanical wear associated with conventional contact-based safety switches.
Designed for integration into modern machine safety and automation systems, the ST HE420N2-H0TE operates from a 24 V DC supply and provides two safety inputs, two safety outputs, one signalling output and one programming input. This flexible I/O configuration enables straightforward integration with safety controllers and supports the creation of sophisticated machine guarding systems.
The ST HE420N2-H0TE features an integrated 2 m cable and the durable technopolymer construction associated with the ST H range. With high ingress protection and a non-contact operating principle, it is well suited to industrial environments where reliable safety monitoring, resistance to contamination and reduced mechanical maintenance are important.
