ST DD611MK-E0T Pizzato ST D series safety sensor

Why Choose the Pizzato ST DD611MK-E0T ST D Series Safety Sensor?

The Pizzato ST DD611MK-E0T is an industrial RFID non-contact safety sensor designed for reliable monitoring of guards, doors and protective devices on automated machinery. Part of the Pizzato ST D series, it combines coded RFID actuator detection with redundant electronic safety outputs to provide dependable machine guard monitoring without mechanical contact between the sensor and actuator.

This configuration uses an E0T large low-level coded RFID actuator with a rated operating distance of 20 mm. The large actuator provides greater operating tolerance than the standard D0T actuator, while low-level coding allows compatible sensors to recognise actuators of the same low-coded type. Non-contact operation eliminates mechanical switching wear and supports reliable performance in applications with frequent guard movements.

The ST DD611MK-E0T operates from a 12–24 V DC supply and provides two safety inputs (IS1 and IS2), two safety outputs (OS1 and OS2) and one inverted signalling output (O3). The MK configuration features an integrated M12 connector with right-side output direction. IP67 and IP69K protection and an operating temperature range of -25 to +70 °C make it suitable for demanding industrial safety applications.

RFID Safety Monitoring with Extended Actuation Distance

RFID safety sensors such as the Pizzato ST D series monitor movable machine guards without requiring physical contact between the sensor and actuator. The E0T version uses a large low-level coded actuator with a rated operating distance of 20 mm. When the actuator enters the sensor's operating range, its RFID transponder is detected electronically, allowing the safety system to determine whether the protective guard is correctly positioned before hazardous machine functions are permitted.

The ST DD611MK-E0T combines two safety inputs and two redundant safety outputs with an inverted O3 signalling output. With this configuration, O3 remains active when the actuator is removed and the safety outputs switch off, allowing an external PLC to verify the sensor's electrical connection. The safety inputs also support integration into compatible series-connected ST sensor systems for flexible machine safety architectures.
