ST GD420H10-L0T Pizzato ST G series safety sensor

Why Choose the Pizzato ST GD420H10-L0T ST G Series Safety Sensor?

The Pizzato ST GD420H10-L0T is a compact and dependable RFID safety sensor designed for non-contact monitoring of 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 outputs to provide reliable guard-position monitoring without the mechanical wear associated with conventional electromechanical switches.

The ST GD420H10-L0T provides two safety inputs IS1–IS2, two OSSD safety outputs OS1–OS2, one signalling output O3 and one programming input I3. This programmable architecture supports integration into sophisticated machine safety circuits and series-connected configurations, while the low-level coded L0T actuator provides straightforward RFID actuation for applications where suitable measures against foreseeable manipulation are implemented.

Operating from a 24 V DC supply, the sensor is supplied with a cable connection and uses the slim L0T front-fixing actuator. The actuator provides an 11 mm actuation distance and measures approximately 53 × 16 × 7 mm, making this configuration particularly useful where installation space around the moving guard is limited. IP67 and IP69K protection further support reliable operation in demanding industrial environments.

Reliable Safety Monitoring for Industrial Automation

RFID safety sensors such as the Pizzato ST G series monitor compatible coded actuators without requiring physical contact between the sensor and moving guard. This reduces mechanical wear and allows reliable detection even where normal machine operation introduces small amounts of guard movement or misalignment.

The ST GD420H10-L0T combines redundant OSSD safety outputs with IS safety inputs and an I3 programming input for integration into modern safety PLC and safety-module architectures. Its slim L0T actuator is particularly useful on compact guards, while the sensor's diagnostic signalling helps operators and maintenance engineers quickly identify operating states.

Typical Applications

• Machine guard and access-door monitoring.
• Compact guards with limited actuator mounting space.
• Automated manufacturing and assembly machinery.
• Packaging and processing equipment.
• Robotic cells and automated production lines.
• Conveyors and material handling systems.
