Why Choose the Pizzato ST DD311N2-D0T ST D Series Safety Sensor?
The Pizzato ST DD311N2-D0T is an industrial RFID non-contact safety sensor with actuator designed for monitoring machine guards, safety doors and protective devices. Part of the Pizzato ST D Series, it uses coded RFID technology to detect the associated actuator without requiring mechanical contact, helping reduce wear in applications with frequent guard-opening cycles.
The ST DD311N2-D0T provides two safety inputs IS1-IS2, two safety outputs OS1-OS2 and one signalling output O3, supporting integration into modern machine-safety architectures and compatible series-connected safety systems. Its semiconductor safety outputs provide electronic guard-status switching, while the dedicated signalling output can communicate additional sensor status information to the automation system.
This N2 version features an integrated 2 m cable with the connection exiting from the right-hand side of the technopolymer housing. The supplied D0T RFID actuator uses a low coding level and provides a 12 mm switch-on distance, while the sensor offers IP67 and IP69K protection for dependable operation in demanding industrial environments.

Reliable RFID Guard Monitoring for Industrial Automation
RFID safety sensors such as the Pizzato ST DD311N2-D0T provide non-contact monitoring of movable machine guards and protective doors. When the D0T actuator enters the sensor's operating zone, the RFID system recognises the coded actuator and enables the safety outputs to communicate the guard condition to the associated machine-safety control system without relying on mechanically operated contacts.
With two safety inputs, two semiconductor safety outputs and a dedicated signalling output, the ST DD311N2-D0T is well suited to modern automated machinery and compatible safety architectures. Its integrated 2 m cable, 12 mm switch-on distance and robust environmental protection provide a practical solution for machine builders requiring dependable, low-maintenance guard monitoring.
Typical Applications
- Machine guard and safety door monitoring.
- Industrial automation and production machinery.
- Packaging and processing equipment.
- Robotic cells and automated manufacturing systems.
- Conveyor and material handling machinery.
- CNC machines and enclosed production equipment.
- OEM machinery requiring RFID-based guard monitoring.
