ST DD421MK-E1T Pizzato ST D series safety sensor

Why Choose the Pizzato ST DD421MK-E1T ST D Series Safety Sensor?

The Pizzato ST DD421MK-E1T is an industrial RFID non-contact safety sensor with E1T actuator designed for reliable monitoring of movable guards, access doors and protective devices. Part of the Pizzato ST D Series, it uses digitally coded RFID technology to detect the associated actuator without mechanical contact, reducing mechanical wear and supporting dependable operation in machinery with frequent guard cycles.

The ST DD421MK-E1T combines safety monitoring functionality with a high-level coded E1T actuator, providing increased resistance to actuator substitution and manipulation. The extended sensing range of the E-format actuator provides greater alignment tolerance than the standard D-format actuator, making it particularly useful for larger guards or installations where some movement between the sensor and actuator may occur.

The MK configuration features an integrated M12 stainless-steel connector with the electrical connection positioned on the right-hand side of the technopolymer housing. The E1T actuator provides a 20 mm actuation distance and measures 40 × 50 × 16 mm with front fixing, while IP67 and IP69K protection and an operating temperature range from -25 °C to +70 °C support installation in demanding industrial environments.

Reliable Safety Monitoring for Industrial Automation

The Pizzato ST D series uses RFID technology to monitor protective guards without requiring mechanical contact between the sensor and actuator. This non-contact operating principle reduces the physical wear associated with conventional mechanically actuated safety switches and is well suited to automated machinery where guards, covers and access doors are opened frequently.

The ST DD421MK-E1T combines high-level RFID actuator coding with an extended 20 mm actuation distance, providing both enhanced protection against actuator substitution and increased installation tolerance. Its integrated M12 stainless-steel connector also allows convenient connection, maintenance and sensor replacement using compatible industrial cabling without a permanently attached sensor cable.

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.
