Why Choose the Pizzato ST DD511MK-D1T Safety Sensor?

The Pizzato ST DD511MK-D1T is a compact RFID non-contact safety sensor with high-coded actuator designed for monitoring 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 reliable guard-position monitoring without mechanical contact between the sensor and actuator.

This configuration provides 2 safety inputs IS1-IS2, 2 semiconductor safety outputs OS1-OS2, 1 signalling output O3 and 1 EDM feedback input. The EDM input enables compatible external switching devices to be monitored, while the safety inputs and outputs support integration into advanced machine safety architectures.

The ST DD511MK-D1T features an integrated 8-pin M12 stainless-steel connector on the right-hand side and uses a D1T high-coded RFID actuator. The actuator provides a 12 mm switch-on distance and 14 mm switch-off distance, while the technopolymer housing, IP67 / IP69K protection and operating temperature range of -25 to +70 °C make the sensor suitable for demanding industrial environments.

Key Advantages

  • Non-contact RFID safety sensing technology minimises mechanical wear.
  • High-coded D1T actuator provides enhanced protection against guard manipulation and actuator substitution.
  • 2 safety inputs and 2 semiconductor safety outputs support flexible machine safety integration.
  • Dedicated O3 signalling output provides additional sensor and guard status information.
  • Integrated EDM feedback input supports external device monitoring.
  • 12 mm switch-on distance provides practical tolerance for guard alignment.
  • 8-pin M12 stainless-steel connector simplifies installation, replacement and maintenance.
  • IP67 / IP69K protection supports use in demanding industrial environments.

Reliable Non-Contact Guard Monitoring for Industrial Automation

RFID safety sensors such as the Pizzato ST DD511MK-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 unique high-level RFID coding provides increased resistance to manipulation by ensuring the sensor recognises its associated coded actuator. Combined with dual safety inputs, dual semiconductor safety outputs, O3 status signalling and EDM feedback, the ST DD511MK-D1T provides a versatile solution for machine builders requiring reliable non-contact guard monitoring and integration into high-integrity 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.
  • Applications requiring external device monitoring.
  • Frequently operated safety guards and protective covers.
  • OEM machinery requiring high-coded RFID guard detection.
