Why Choose the Pizzato ST DD511N2-D1T Safety Sensor?
The Pizzato ST DD511N2-D1T is an RFID non-contact safety sensor with high-coded actuator designed for reliable monitoring of guards, doors, covers and other movable protective devices on industrial machinery. Part of the Pizzato ST D series, it combines RFID actuator recognition with redundant electronic safety outputs to provide dependable guard-position monitoring without mechanical contact between the sensor and actuator.
The ST DD511N2-D1T configuration provides 2 safety inputs IS1-IS2, 2 safety outputs OS1-OS2, 1 signalling output O3 and 1 EDM feedback input. The EDM input supports external device monitoring, while the safety inputs enable integration with other compatible safety devices for flexible machine safety architectures.
This model uses an integrated 2 m PVC cable routed from the right-hand side of the sensor and is paired with a D1T high-coded RFID actuator. The D-format actuator provides a 12 mm actuation distance, while the rugged technopolymer construction, IP67 / IP69K protection and operating temperature range of -25 to +70 °C support reliable operation in demanding industrial environments.

Reliable Non-Contact Guard Monitoring for Industrial Automation
RFID safety sensors such as the Pizzato ST DD511N2-D1T monitor movable machine guards without requiring physical contact between the sensor and actuator. When the associated high-coded D1T actuator enters the sensor's operating zone, the electronic safety outputs communicate the guard condition to the safety controller or safety circuit, helping machinery operate only when the required safety conditions are satisfied.
The high-coded RFID actuator provides increased resistance to manipulation by requiring recognition of the associated coded actuator. Combined with dual safety inputs, dual safety outputs, O3 status signalling and EDM feedback, the ST DD511N2-D1T provides machine builders with a flexible solution for non-contact guard monitoring and integration into high-integrity industrial safety systems.
Typical Applications
- Machine guard and access door monitoring.
- Industrial automation and robotic cells.
- Packaging and processing machinery.
- Conveyor and material handling systems.
- Machine tools and automated manufacturing equipment.
