ST DD211MK-E1T Pizzato ST D series safety sensor

Why Choose the Pizzato ST DD211MK-E1T ST D Series Safety Sensor?

The Pizzato ST DD211MK-E1T is an advanced RFID safety sensor designed for reliable non-contact monitoring of guards, doors and access points on industrial machinery. Part of the Pizzato ST D series, it combines digitally coded RFID technology with electronic safety outputs to provide dependable machine guard monitoring without mechanical contact between the sensor and actuator.

The ST DD211MK-E1T provides two OS1-OS2 safety outputs and one O3 signalling output, allowing integration with compatible safety modules, controllers and safety PLCs. Its E1T high coding level RFID actuator provides enhanced protection against actuator substitution and manipulation, making it well suited to safety applications requiring coded guard monitoring.

Operating across a 10–30 V DC supply range, the ST DD211MK-E1T features an integrated M12 stainless steel connector for robust, detachable machine wiring. The E-type actuator configuration provides a generous 20 mm actuation distance, while the technopolymer housing, IP67 / IP69K protection and operating temperature range from -25 to +70 °C support reliable use in demanding industrial environments.

High-Coded Non-Contact RFID Safety Monitoring

The Pizzato ST D series uses RFID technology to monitor movable machine guards without requiring physical contact between the sensor and actuator. When the correctly coded actuator enters the sensing zone, the sensor electronically verifies its presence and provides safety signals through the OS1 and OS2 outputs for evaluation by a compatible safety-related control system.

The ST DD211MK-E1T combines this non-contact operating principle with high-level RFID coding, an extended 20 mm actuation distance and a durable integrated M12 stainless steel connector. This configuration is particularly suitable for machinery where resistance to manipulation, increased guard alignment tolerance and convenient detachable wiring are important.

Typical Applications

• Machine guard and safety door monitoring.
• Robotic cells and guarded automation systems.
• Packaging and production machinery.
• Material handling and conveyor systems.
• Automated manufacturing cells.
• Processing and assembly machinery.
• Industrial machinery requiring detachable M12 sensor connections.
• OEM machinery requiring high-coded RFID safety monitoring.
