Why Choose the Pizzato ST DD311MK-D0T ST D Series Safety Sensor?
The Pizzato ST DD311MK-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, providing reliable guard-position monitoring while reducing mechanical wear.
The ST DD311MK-D0T provides two safety inputs IS1-IS2, two safety outputs OS1-OS2 and one signalling output O3, enabling flexible integration with compatible safety controllers and machine-safety architectures. The redundant electronic safety outputs provide dependable safety-related switching, while the dedicated signalling output can provide additional sensor status information to the automation system.
The MK connection version features an integrated M12 stainless-steel connector, providing a compact and service-friendly plug-in connection without a permanently attached cable. The supplied D0T RFID actuator uses a low coding level and provides a 12 mm actuation distance, while the robust technopolymer construction provides IP67 and IP69K protection for demanding industrial environments.

Reliable RFID Guard Monitoring for Industrial Automation
RFID safety sensors such as the Pizzato ST DD311MK-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 allows the safety outputs to communicate the guard condition to the associated machine-safety control system without relying on mechanically operated contacts.
The combination of two safety inputs, two safety outputs and a dedicated signalling output makes the ST DD311MK-D0T suitable for integration into modern automated machinery and compatible safety architectures. Its compact M12 stainless-steel connector simplifies wiring and servicing, while the 12 mm sensing distance and non-contact operating principle provide practical installation tolerance and reduced mechanical maintenance.
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 plug-in RFID guard monitoring.
