Why Choose the Pizzato ST HE420MK-H0TE Safety Sensor?
The Pizzato ST HE420MK-H0TE is an advanced RFID non-contact safety sensor with magnetic holding designed for reliable monitoring of guards, doors and access points on industrial machinery. As part of the Pizzato ST H series, it combines coded RFID actuator detection with electronic safety inputs and outputs, providing a robust solution for machine guarding, safety interlocking and industrial automation.
The ST HE420MK-H0TE provides two safety inputs IS1–IS2, two safety outputs OS1–OS2, one signalling output O3 and one programming input I3. This flexible electronic architecture supports integration into modern machine safety systems and series-connected guarding applications. Its low-level coded RFID actuator provides reliable non-contact detection while eliminating the mechanical engagement and associated wear of conventional safety switches.
Operating from a 24 V DC supply, the ST HE420MK-H0TE features an integrated M12 stainless steel connector for convenient machine wiring and servicing. The sensor has an 11 mm actuation distance and incorporates a permanent magnet providing approximately 25 N holding force. Its technopolymer housing, IP67 / IP69K protection and -25 °C to +70 °C operating range make it suitable for demanding industrial environments.

Reliable Safety Monitoring for Industrial Automation
RFID safety sensors such as the Pizzato ST HE420MK-H0TE monitor movable machine guards without requiring mechanical contact between the sensor and actuator. When the coded actuator enters the sensor's operating range, the electronic safety outputs communicate the guard condition to the connected safety controller, helping the machine safety system determine whether hazardous functions can operate.
The ST H series combines RFID guard monitoring with magnetic holding for applications where a guard benefits from being retained in its closed position during normal operation. The ST HE420MK-H0TE also provides safety inputs, dual safety outputs, a signalling output and a programming input, making it a versatile choice for OEM machinery, automated production systems and installations incorporating multiple guarded access points.
Typical Applications
- Machine guard and safety-door monitoring.
- Safety interlocking systems.
- Automated production and assembly machinery.
- Robot cells and robotic manufacturing systems.
- Packaging and processing equipment.
- Conveyors and material handling systems.
