Why Choose the Pizzato ST DD311N2-D1T ST D Series Safety Sensor?
The Pizzato ST DD311N2-D1T 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 machinery with frequent guard-opening cycles.
The ST DD311N2-D1T provides two safety inputs IS1-IS2, two semiconductor safety outputs OS1-OS2 and one signalling output O3, supporting integration into modern machine-safety architectures and compatible series-connected safety systems. Its electronic operating principle provides dependable guard-status switching without the mechanical contacts found in conventional interlock switches.
This N2 version features an integrated 2 m cable with the output connection positioned on the right-hand side of the technopolymer housing. The supplied D1T RFID actuator provides a high coding level, a 12 mm switch-on distance and a 14 mm switch-off distance, while IP67 and IP69K protection supports installation in demanding industrial environments.

Reliable High-Coded RFID Guard Monitoring for Industrial Automation
RFID safety sensors such as the Pizzato ST DD311N2-D1T provide non-contact monitoring of movable machine guards and protective doors. When the D1T 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.
The high-coded D1T actuator makes the ST DD311N2-D1T particularly suitable for applications where enhanced protection against actuator substitution is required. Combined with two safety inputs, two semiconductor safety outputs, a signalling output and an integrated 2 m cable, the sensor provides a practical solution for dependable guard monitoring across modern automated machinery.
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 high-coded RFID guard monitoring.
