ST HE420MP-H0TG Pizzato ST H series safety sensor

Why Choose the Pizzato ST HE420MP-H0TG Safety Sensor?

The Pizzato ST HE420MP-H0TG 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-H0TG provides two safety inputs IS1–IS2, two safety outputs OS1–OS2, one signalling output O3 and one programming input I3. This programmable architecture supports integration into modern machine safety systems and compatible series-connected guarding applications, while non-contact RFID detection eliminates mechanical engagement between the sensor and actuator.

Operating from a 24 V DC supply, the ST HE420MP-H0TG features an integrated M12 technopolymer connector. The H0TG configuration incorporates a permanent magnet providing 50 N holding force, while the ST H platform provides an 11 mm actuation distance, IP67 / IP69K protection and an operating temperature range of -25 °C to +70 °C.

Key Advantages

• Non-contact RFID safety sensing reduces mechanical wear and maintenance requirements.
• Two safety inputs IS1–IS2 support integration into compatible series-connected safety architectures.

Reliable Safety Monitoring for Industrial Automation

RFID safety sensors such as the Pizzato ST HE420MP-H0TG 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 machinery 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 50 N permanent magnet provides increased 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.
