Why Choose the Pizzato ST HE420MP-H0TE Safety Sensor?
The Pizzato ST HE420MP-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. Part of the Pizzato ST H series, it combines coded RFID actuator detection with electronic safety inputs and outputs, providing a dependable solution for machine guarding, safety interlocking and industrial automation.
The ST HE420MP-H0TE provides two safety inputs IS1–IS2, two safety outputs OS1–OS2, one signalling output O3 and one programming input I3. Its low-level coded RFID actuator is detected without mechanical contact, reducing wear compared with conventional electromechanical safety switches while supporting flexible integration into modern machinery safety systems.
Operating from a 24 V DC supply, the ST HE420MP-H0TE features an integrated 8-pole M12 technopolymer connector. The H0TE configuration incorporates a permanent magnet providing 25 N holding force, together with an 11 mm actuation distance, IP67 / IP69K protection and an operating temperature range of -25 °C to +70 °C.

Reliable Safety Monitoring for Industrial Automation
RFID safety sensors such as the Pizzato ST HE420MP-H0TE monitor movable machine guards without requiring mechanical engagement 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, allowing the machine safety system to determine whether the required guarding conditions are satisfied.
The ST H series combines RFID guard monitoring with magnetic retention for applications where a guard benefits from being held in its closed position during normal operation. The 25 N permanent magnet provides guard retention, while the safety inputs, dual safety outputs, signalling output and programming input provide flexible integration into modern industrial safety architectures.
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.
