ST GD420MP-L0T Pizzato ST G series safety sensor

Why Choose the Pizzato ST GD420MP-L0T ST G Series Safety Sensor?

The Pizzato ST GD420MP-L0T is a compact 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 RFID Safety Sensor Series, it combines RFID transponder detection with electronic safety circuitry to provide dependable guard-position monitoring without the mechanical wear associated with conventional electromechanical interlock switches.

The ST GD420MP-L0T operates from a 24 V DC supply and provides two safety inputs IS1–IS2, two safety outputs OS1–OS2, one signalling output O3 and one programming input I3. Its programmable GD420 architecture supports integration with modern safety PLCs, safety modules and compatible series-connected safety devices, providing a flexible solution for machine guarding and industrial automation systems.

This MP version features an integrated M12 technopolymer connector and is paired with the SM L0T miniaturised low-level coded RFID actuator. The compact L0T actuator provides an approximately 11 mm actuation distance and measures 53 × 16 × 7 mm with front fixing, making this configuration particularly useful where actuator mounting space is limited. IP67 / IP69K protection and an operating temperature range of -25 to +70 °C support reliable operation in demanding industrial environments.

Reliable Safety Interlocking for Industrial Automation

The Pizzato ST G series uses RFID transponder technology to detect a compatible coded actuator without requiring physical contact between the sensor and moving guard. This non-contact operating principle reduces mechanical wear and supports dependable guard monitoring on machinery exposed to frequent operating cycles, vibration and normal alignment tolerances. The miniaturised L0T actuator makes the ST GD420MP-L0T especially suitable for compact doors, covers and guards where available mounting space is restricted.

The ST GD420MP-L0T combines two safety inputs, two safety outputs, signalling output O3 and programming input I3 in a programmable electronic safety architecture. Its low-level coded L0T actuator uses the standard low-coded recognition system, while the integrated M12 technopolymer connector provides convenient detachable wiring for installation, replacement and maintenance within modular industrial automation systems.
