ST DD420M0.5-L1T Pizzato ST D series safety sensor

Why Choose the Pizzato ST DD420M0.5-L1T ST D Series Safety Sensor?

The Pizzato ST DD420M0.5-L1T is a robust RFID non-contact safety sensor designed for reliable monitoring of guards, doors and protective devices on industrial machinery. As part of the Pizzato ST D series, it combines coded RFID detection with electronic safety inputs and outputs to provide dependable machine safeguarding without the mechanical wear associated with conventional electromechanical switches.

The ST DD420 configuration provides two safety inputs IS1-IS2, two safety outputs OS1-OS2, one signalling output O3 and one programming input I3, allowing flexible integration into modern industrial safety systems. Its non-contact operating principle supports frequent switching cycles while helping minimise mechanical wear and alignment-related maintenance.

The ST DD420M0.5-L1T operates from a 24 V DC supply and features a PVC cable with M12 connector. It is configured for a high-level coded actuator with a 12 mm actuation distance and a slim 53 × 16 × 7 mm actuator format with frontal fixing, making it particularly suitable for compact machine guards and access points.

Reliable Safety Monitoring for Industrial Automation

RFID safety sensors such as the Pizzato ST D series detect a coded actuator without requiring physical contact between the sensor and actuator. This enables dependable monitoring of movable guards while reducing mechanical wear, making the technology particularly suitable for automated machinery with frequent access cycles and demanding operating conditions.

The ST DD420M0.5-L1T combines dual safety inputs and outputs with a signalling output and programming input for flexible integration into industrial safety architectures. Its high-level coded actuator configuration helps increase protection against bypassing or manipulation, while the slim frontal-fixing actuator makes installation practical where available mounting space is limited.

Typical Applications

• Machine guard and access-door monitoring.
• Automated production and assembly machinery.
• Packaging and processing equipment.
• Robotic cells and automated manufacturing systems.
• Conveyors and material handling equipment.
• Industrial machinery requiring high-level coded non-contact safety interlocking.
