ST GD420N5-L1T Pizzato ST G series safety sensor

Why Choose the Pizzato ST GD420N5-L1T ST G Series Safety Sensor?

The Pizzato ST GD420N5-L1T is a compact and highly reliable RFID safety sensor with high-level coded actuator designed for non-contact monitoring of guards, doors and access points on industrial machinery. As part of the advanced Pizzato ST G series, it combines RFID actuator recognition with redundant electronic safety outputs to provide dependable machine guarding and safety interlocking in modern automation systems.

The ST GD420N5-L1T provides two safety inputs IS1–IS2, two safety outputs OS1–OS2, one signalling output O3 and one programming input I3. The programmable architecture supports integration with safety modules and safety PLCs, while the high-level coded 1T actuator uses an individual RFID code so that only the specifically associated actuator is recognised until a new association procedure is performed.

Operating from a 24 V DC supply, this N5 version features an integrated 5 m PVC cable and is paired with the compact SM L1T high-level coded actuator. The miniaturised L-style actuator measures approximately 53 × 16 × 7 mm, uses frontal fixing and provides an 11 mm actuation distance, making this configuration particularly suitable for machine guards where available installation space is restricted.

Key Advantages

• Compact RFID safety sensor for machine guarding and safety interlocking.
• High-level coded SM L1T actuator provides individual RFID recognition and enhanced protection against manipulation.
• Miniaturised 53 × 16 × 7 mm actuator is well suited to space-constrained guard installations.
• 11 mm actuation distance provides practical positioning tolerance for movable guards.
• Two safety inputs and two safety outputs support integration into series-connected safety architectures.
• 5 m PVC cable provides convenient direct wiring into industrial control systems.

Reliable Safety Monitoring for Industrial Automation

RFID safety sensors such as the Pizzato ST GD420N5-L1T monitor movable machine guards without requiring physical contact between the sensor and actuator. When the associated high-level coded actuator moves outside the permitted detection zone, the electronic safety outputs change state so that the connected safety module or safety PLC can initiate the required safe machine response.

The ST G series is designed for machine builders requiring compact installation, dependable coded guard detection and flexible integration with modern safety controls. The miniaturised SM L1T actuator is only 7 mm thick and uses frontal fixing, making it particularly useful on small guards and machinery where conventional actuator formats may be difficult to accommodate.

Typical Applications

• Compact machine guard doors and access panels.
• Industrial production and assembly machinery.
• Robotic cells and automated manufacturing systems.
• Packaging and processing equipment.
• Machinery with restricted actuator installation space.
• Safety interlocking systems using safety PLCs or safety modules.
