ST DD420N5-E1T Pizzato ST D series safety sensor

Why Choose the Pizzato ST DD420N5-E1T ST D Series Safety Sensor?

The Pizzato ST DD420N5-E1T 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, reducing mechanical wear and supporting dependable operation in machinery with frequent guard-opening cycles.

The ST DD420 configuration provides two safety inputs IS1 and IS2, two safety outputs OS1 and OS2, one signalling output O3 and one programming input I3. The E1T actuator uses a high coding level, providing increased resistance to actuator substitution and making this configuration particularly suitable for machine safety applications where protection against manipulation is important.

Operating from a 24 V DC supply, the ST DD420N5-E1T features an integrated 5 m PVC cable for direct machine wiring. Its E1T actuator provides an extended 20 mm actuation distance and measures approximately 40 × 50 × 16 mm with front fixing. Combined with IP67 / IP69K protection and an operating temperature range from -25 °C to +70 °C, the sensor is well suited to demanding industrial automation environments.

Key Advantages

• Non-contact RFID safety monitoring reduces mechanical wear during frequent guard operation.
• E1T high-level coded actuator provides enhanced resistance to actuator substitution and manipulation.

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 operating principle reduces mechanical wear and supports consistent safety monitoring in automated machinery where guards, covers and access doors may be opened and closed frequently.

The ST DD420N5-E1T combines dual safety inputs and outputs with dedicated signalling and programming functionality for flexible integration into compatible industrial safety architectures. Its high-level coded E1T actuator provides enhanced protection against actuator substitution, while the extended 20 mm actuation distance offers increased alignment tolerance and the integrated 5 m cable provides flexibility when positioning the sensor away from the 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.
