ST HE420N2-H0TE Pizzato ST H series safety sensor

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.

Reliable Safety Monitoring for Industrial Automation

RFID safety sensors such as the Pizzato ST HE420N2-H0TE monitor the position of machine guards by detecting a coded actuator without physical contact between the sensor and actuator. This non-contact operating principle reduces mechanical wear while helping maintain reliable guard detection throughout repeated machine operating cycles.

The ST H series is designed for machine builders and industrial automation engineers requiring flexible integration with modern safety control systems. Its dual safety inputs and outputs, signalling output and programming input allow the sensor to form part of sophisticated machine safety architectures while supporting reliable status monitoring and diagnostics.
