Why Choose the Pizzato ST GD420MP-L1T ST G Series Safety Sensor?

The Pizzato ST GD420MP-L1T 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 safety switches.

The ST GD420MP-L1T 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, making it 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 L1T miniaturised high-level coded RFID actuator. The L1T actuator provides an 11 mm actuation distance and measures 53 × 16 × 7 mm with front fixing, making it particularly suitable 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.

Key Advantages

  • Non-contact RFID safety monitoring reduces mechanical wear on frequently operated machine guards.
  • Miniaturised SM L1T actuator provides a compact solution for space-constrained guard installations.
  • High-level RFID coding provides enhanced protection against inappropriate actuator substitution.
  • Two safety inputs and two safety outputs support flexible machine safety architectures and series connections.
  • Integrated M12 technopolymer connector simplifies installation, replacement and servicing.
  • IP67 / IP69K protection supports dependable 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 L1T actuator makes the ST GD420MP-L1T particularly suitable for compact doors, covers and guards where available mounting space is restricted.

The ST GD420MP-L1T combines two safety inputs, two safety outputs, signalling output O3 and programming input I3 in a programmable electronic safety architecture. Its high-level coded L1T actuator provides enhanced RFID identification for guard monitoring, while the integrated M12 technopolymer connector provides convenient detachable wiring for installation, replacement and maintenance within modern industrial automation systems.

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.
  • Conveyor and material handling systems.
  • OEM machinery requiring high-level coded electronic safety interlocking.
