Why Choose the Pizzato ST DD821N2-E1T Safety Sensor?

The Pizzato ST DD821N2-E1T is a compact and reliable RFID-coded non-contact safety sensor designed for monitoring the position of guards, doors and access panels on industrial machinery. As part of the Pizzato ST D series safety sensor range, it provides dependable electronic guard monitoring for machine safety and industrial automation applications.

The ST D series uses coded electronic RFID technology to detect the associated actuator without mechanical contact. The high coding level of the E1T actuator means the sensor is paired to one specific actuator code, providing enhanced protection against actuator substitution in machine guarding applications.

The ST DD821N2-E1T combines a 24 V DC supply, cable connection, two safety outputs, two safety inputs and a programming input. It is designed for use with the large E1T actuator, which provides a 20 mm actuation distance and flexible front fixing for industrial safety installations.

Key Advantages

  • Compact RFID-coded non-contact safety sensor for industrial machinery.
  • Part of the Pizzato ST D series safety sensor range.
  • High coding level actuator technology helps reduce the risk of actuator substitution.
  • 24 V DC operation for industrial safety control systems.
  • 20 mm actuation distance with the large E1T actuator.
  • Non-contact operation helps minimise mechanical wear and maintenance.
  • IP67 and IP69K protection supports use in demanding industrial environments.

Key Features

  • Pizzato ST D series safety sensor.
  • ST DD821N2-E1T model configuration.
  • RFID-coded non-contact switching technology.
  • High coding level E1T actuator for individually coded detection.
  • 24 V DC power supply.
  • 2 safety outputs, 1 inverted signalling output and 2 safety inputs.
  • Programming input for actuator coding functions.
  • 20 mm actuator actuation distance.
  • Large E-type actuator measuring 40 × 50 × 16 mm with front fixing.
  • Non-contact sensing helps provide long service life with reduced mechanical wear.

Reliable Safety Monitoring for Industrial Automation

RFID-coded safety sensors such as the Pizzato ST DD821N2-E1T provide non-contact monitoring of movable machine guards. The sensor detects its correctly coded actuator and supplies the safety system with information about the guard position, helping prevent hazardous machine operation when the required guarding condition is not satisfied.

The ST D series is designed for modern machine safety applications where reliable electronic guard monitoring, compact installation and reduced mechanical wear are important. The two safety outputs and safety inputs allow the sensor to be incorporated into suitable safety control architectures, while the programming input supports the sensor's RFID actuator coding functionality.

Typical Applications

  • Industrial machine guarding systems.
  • Safety monitoring of machine doors and access panels.
  • Packaging and production machinery.
  • Automated manufacturing equipment.
  • Conveyors and material handling machinery.
  • OEM machinery and industrial automation systems.
