Why Choose the Pizzato ST HE420MP-H1T Safety Sensor?
The Pizzato ST HE420MP-H1T is an RFID non-contact safety sensor from the Pizzato ST H series, designed for dependable monitoring of guards, doors and access points on industrial machinery. It combines high-level coded RFID actuator detection with electronic safety inputs and outputs, providing a robust solution for machine guarding, safety interlocking and industrial automation.
The ST HE420MP-H1T provides two safety inputs IS1–IS2, two safety outputs OS1–OS2, one signalling output O3 and one programming input I3. Its programmable electronic architecture supports integration into modern machinery safety systems and compatible series-connected guarding applications, while high-level RFID coding provides enhanced resistance to actuator substitution and manipulation.
Operating from a 24 V DC supply, the ST HE420MP-H1T features an integrated M12 connector for convenient detachable machine wiring. Non-contact operation eliminates mechanical engagement between the sensor and actuator, helping reduce wear while providing reliable guard-position monitoring in demanding industrial environments.

Reliable Safety Monitoring for Industrial Automation
RFID safety sensors such as the Pizzato ST HE420MP-H1T monitor movable machine guards without requiring mechanical engagement between the sensor and actuator. When the correctly coded actuator is detected, the electronic safety outputs communicate the guard condition to the connected safety controller, helping the machine safety system determine whether the required guarding conditions have been satisfied.
The ST HE420 architecture adds safety inputs and a programming input alongside its dual safety outputs and signalling output, providing flexible integration into sophisticated industrial safety systems. Combined with high-level RFID actuator coding and connector-based installation, the ST HE420MP-H1T is well suited to OEM machinery, automated production equipment 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.
