ST DD420N5-E0T Pizzato ST D series safety sensor

Why Choose the Pizzato ST DD420N5-E0T ST D Series Safety Sensor?

The Pizzato ST DD420N5-E0T is an industrial RFID non-contact safety sensor with actuator designed for reliable monitoring of movable guards, access doors and protective devices. Part of the Pizzato ST D Series, it uses coded RFID technology to detect the associated actuator without mechanical contact, helping minimise component wear and providing dependable switching in machinery with frequent operating cycles.

The ST DD420N5-E0T provides two safety inputs IS1 and IS2, two safety outputs OS1 and OS2, one signalling output O3 and one programming input I3. Its PNP electronic switching architecture supports integration into modern machine safety systems, while the E0T actuator uses a low coding level for straightforward RFID guard detection.

Operating from a 24 V DC supply, this N5 configuration features an integrated 5 m oil-resistant PVC cable exiting from the right-hand side of the technopolymer housing. The E0T actuator provides an extended 20 mm actuation distance and measures 40 × 50 × 16 mm with front fixing. An operating temperature range from -25 °C to +70 °C and IP67 / IP69K protection support reliable operation in demanding industrial environments.

Key Advantages

• Non-contact RFID safety monitoring reduces mechanical wear during frequent guard operation.
• Extended 20 mm actuation distance provides generous sensor-to-actuator alignment tolerance.
• Two safety inputs and two safety outputs support flexible integration into machine safety architectures.
• E0T low-level coded actuator provides straightforward RFID guard detection.

Reliable Safety Monitoring for Industrial Automation

The Pizzato ST D series uses RFID technology to monitor movable guards without requiring physical contact between the sensor and actuator. This non-contact principle eliminates the mechanical switching wear associated with conventional safety switches and supports reliable operation in automated machinery where doors, covers and guards may be opened and closed frequently.

The ST DD420N5-E0T combines dual safety inputs and outputs with dedicated signalling and programming functionality for flexible integration into compatible industrial safety architectures. Its E0T actuator provides an extended 20 mm sensing distance for increased alignment tolerance, while the integrated 5 m oil-resistant PVC cable offers practical installation flexibility where the sensor is positioned away from the main control enclosure.

Typical Applications

• Machine guard and access-door monitoring.
• Guards requiring increased sensor-to-actuator alignment tolerance.
• Automated production and assembly machinery.
• Packaging and processing equipment.
• Robotic cells and automated manufacturing systems.
• Conveyors and material handling machinery.
