Why Choose the Pizzato ST GD420MK-D1T ST G Series Safety Sensor?
The Pizzato ST GD420MK-D1T is a compact and highly reliable 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-D1T provides two safety inputs IS1–IS2, two OSSD safety outputs OS1–OS2, one signalling output O3 and one programming input I3. Its programmable architecture supports integration with modern safety PLCs and safety modules, while the high-level coded D1T actuator uses an individual RFID code to provide enhanced protection against inappropriate actuator substitution and manipulation.
Operating from a 24 V DC supply, this version features an integrated stainless-steel M12 connector for robust and convenient machine wiring. The D1T actuator provides an 11 mm actuation distance, measures 45 × 25 × 18 mm and supports front and side fixing, while IP67 and IP69K protection makes the assembly suitable for demanding industrial environments.

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 guard monitoring on machinery exposed to repeated movement, vibration and normal alignment tolerances.
The ST GD420MK-D1T combines redundant OSSD safety outputs with safety inputs and an I3 programming input for integration into modern industrial safety architectures. Its individually coded D1T actuator provides a high coding level, while the integrated stainless-steel M12 connector simplifies installation, replacement and maintenance within modular machine wiring systems.
Typical Applications
- Machine guard and access-door monitoring.
- Automated manufacturing and assembly machinery.
- Packaging and processing equipment.
- Food and beverage production machinery.
