ST DD511MK-D0T Pizzato ST D series safety sensor

Why Choose the Pizzato ST DD511MK-D0T Safety Sensor?

The Pizzato ST DD511MK-D0T is a compact and robust RFID non-contact safety sensor with coded actuator designed for monitoring guards, doors, covers and other movable protective devices on industrial machinery. As part of the Pizzato ST D series safety sensors, it uses RFID technology and redundant electronic safety outputs to provide dependable guard-position monitoring without mechanical contact between the sensor and actuator.

This 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 dual safety inputs and outputs enable flexible integration with compatible safety controllers and other Pizzato safety devices in modern machine safety architectures.

The ST DD511MK-D0T operates from a 10–30 V DC supply and features an integrated 8-pin M12 stainless-steel connector with the connection output on the right-hand side. Its low-coded D0T RFID actuator provides a 12 mm switch-on distance, while the technopolymer housing and IP67 / IP69K protection provide dependable operation in demanding industrial environments.

Reliable Non-Contact Guard Monitoring for Industrial Automation

RFID safety sensors such as the Pizzato ST DD511MK-D0T monitor the position of movable machine guards without requiring physical contact between the sensor and actuator. When the coded D0T actuator enters the sensor's operating zone, the electronic safety outputs communicate the guard condition to the associated safety controller or safety circuit, helping ensure machinery operates only when the required safety conditions are satisfied.

The ST D series uses redundant electronics and can be integrated into high-integrity machine safety architectures. Compatible sensors can also be connected in series, with up to 32 sensors supported while maintaining PL e when the system is correctly designed. Combined with EDM feedback, status signalling and non-contact RFID detection, the ST DD511MK-D0T provides a versatile solution for modern automated machinery.

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.
• Applications requiring external device monitoring.
• Frequently operated safety guards and protective covers.
• OEM machinery and integrated functional safety systems.
