ST GD420MK-E0T Pizzato ST G series safety sensor

Why Choose the Pizzato ST GD420MK-E0T ST G Series Safety Sensor?

The Pizzato ST GD420MK-E0T is a compact and robust RFID safety sensor designed for non-contact monitoring of movable guards, doors and protective access points on industrial machinery. Part of the Pizzato ST G series, it combines RFID transponder technology with redundant electronic safety circuitry to provide dependable guard-position monitoring without the mechanical wear associated with conventional electromechanical safety switches.

The ST GD420MK-E0T provides two safety inputs IS1–IS2, two OSSD safety outputs OS1–OS2, one signalling output O3 and one programming input I3. This architecture supports integration with modern safety PLCs and safety modules, while the E0T actuator uses a low coding level in accordance with ISO 14119 for straightforward replacement and operation with compatible E0T actuators.

Operating from a 24 V DC supply, the ST GD420MK-E0T uses an integrated M12 connector for convenient industrial wiring. The large SM E0T actuator provides an 18 mm actuation distance and measures approximately 40 × 50 × 16 mm with front fixing, offering generous operating tolerance for larger machine guards. IP67 and IP69K protection further support reliable operation in demanding industrial environments.

Key Advantages

• Advanced RFID non-contact safety sensing for industrial machine guards and access doors.

Reliable Safety Monitoring for Industrial Automation

RFID safety sensors such as the Pizzato ST G series detect compatible coded actuators without requiring physical contact between the sensor and moving guard. This non-contact operating principle reduces mechanical wear and provides dependable monitoring on machinery exposed to repeated guard movement, vibration and normal alignment tolerances.

The ST GD420MK-E0T combines redundant OSSD safety outputs with safety inputs and an I3 programming input for integration into modern industrial safety architectures. Its E0T actuator uses a common low-level RFID code, meaning compatible E0T actuators can be recognised without individual actuator association, while the large actuator and extended detection distance provide additional installation flexibility.

Typical Applications

• Machine guard and access-door monitoring.
• Large industrial doors and movable protective guards.
• Automated manufacturing and assembly machinery.
• Packaging and processing equipment.
• Robotic cells and automated production lines.
• Conveyors and material handling systems.
