Why Choose the Pizzato ST DD611MK-E1T ST D Series Safety Sensor?
The Pizzato ST DD611MK-E1T 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 E1T large high-level coded RFID actuator with a rated operating distance of 20 mm. High-level coding means the sensor recognises its specifically associated actuator, providing increased protection against inappropriate actuator substitution and manipulation in accordance with EN ISO 14119. The large E1T actuator also provides greater operating tolerance than the standard D1T actuator.
The ST DD611MK-E1T 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, a reinforced technopolymer housing and an operating temperature range of -25 to +70 °C make it suitable for demanding industrial safety applications.

High-Coded 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 E1T version uses a large high-level coded actuator with a rated operating distance of 20 mm. When its specifically associated actuator enters the sensor's operating range, the RFID identity is detected electronically, allowing the safety system to verify that the protective guard is correctly positioned before hazardous machine functions are permitted.
The ST DD611MK-E1T combines two safety inputs and two redundant safety outputs with an inverted O3 signalling output. The safety inputs allow compatible safety devices to be connected in series, while the signalling output provides additional status information to the machine control system. Combined with high-level RFID coding, extended sensing distance and convenient M12 connectivity, this configuration provides a flexible solution for sophisticated industrial safety architectures.
