Why Choose the Pizzato ST HE420N10-H1TF Safety Sensor?
The Pizzato ST HE420N10-H1TF is an advanced RFID non-contact safety sensor with permanent magnetic holding from the Pizzato ST H series, designed for reliable monitoring of guards, doors and access points on industrial machinery. Its electronic RFID technology provides dependable actuator detection without mechanical contact, making it well suited to machine guarding, safety interlocking and industrial automation.
The ST HE420 architecture provides two safety inputs IS1–IS2, two safety outputs OS1–OS2, one signalling output O3 and one programming input I3. The H1TF configuration uses a high-level coded RFID actuator for enhanced resistance to manipulation and incorporates a permanent magnet providing 40 N holding force to help retain the associated guard in its closed position.
Operating from a 24 V DC supply, the N10 version is equipped with an integrated 10 m cable for direct machine wiring. The ST H platform provides an 11 mm actuation distance, IP67 / IP69K environmental protection and a standard operating temperature range of -25 °C to +70 °C, supporting dependable installation in demanding industrial environments.

Reliable Safety Monitoring for Industrial Automation
RFID safety sensors such as the Pizzato ST HE420N10-H1TF monitor movable machine guards without requiring mechanical engagement between the sensor and actuator. When the correctly coded actuator enters the sensor's 11 mm actuation range, the electronic safety outputs communicate the guard condition to the connected safety controller, supporting reliable monitoring of guarded machinery and automated equipment.
The HE420 architecture combines safety inputs, dual safety outputs, a signalling output and a programming input for flexible integration into sophisticated industrial safety systems. The H1TF configuration adds high-level RFID coding and 40 N permanent magnetic retention, while the factory-fitted 10 m cable provides a practical connection option for installations requiring longer direct cable runs.
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.
