ST DD611N5-D0T Pizzato ST D series safety sensor

Why Choose the Pizzato ST DD611N5-D0T ST D Series Safety Sensor?

The Pizzato ST DD611N5-D0T 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 a D0T standard low-level coded RFID actuator with a rated operating distance of 12 mm. Low-level coding allows compatible sensors to recognise actuators of the same low-coded type, while the non-contact sensing principle eliminates mechanical switching wear and provides useful mounting tolerance for applications involving frequent guard movements.

The ST DD611N5-D0T 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 N5 configuration features an integrated 5 m PVC cable with right-side output. IP67 and IP69K protection and an operating temperature range of -25 to +70 °C make it suitable for demanding industrial safety applications.

Reliable RFID Safety Monitoring for Industrial Machinery

Pizzato ST D series sensors are coded type 4 non-contact interlocking devices designed for monitoring movable machine guards. When the D0T actuator enters the sensor's operating range, its RFID transponder is detected electronically and the safety outputs can indicate that the protective guard is correctly positioned before hazardous machine functions are permitted.

The ST DD611N5-D0T combines two safety inputs and two redundant safety outputs with an inverted O3 signalling output. The safety inputs support compatible series-connected safety architectures, while the inverted signalling output provides additional status information to a PLC or machine control system. ST D sensors can be used in suitable series-connected architectures of up to 32 devices while maintaining PL e when correctly integrated with the required safety control equipment.
