Object Detection Ultrasonic Sensor

IRU-2000

Designed For Detecting Solids And Moving Objects

The IRU-2000 Object Detection Ultrasonic Sensor is designed for absence/presence detection, object profiling, and more. With a surface mount design, it easily installs on walls, ceilings, and flat surfaces. The ultrasonic transducers offer reliable solid and moving object detection across multiple industrial applications.

  • Versatile Programming Options: Customizable to suit a variety of detection needs.
  • Surface Mount Design: Eliminates the need for threaded fittings, ensuring quick installation.
  • Multiple Output Options: Choose from solid-state relay, 4-20mA, and RS-485 with NPN trip points.
  • Wide Detection Range: Up to 25 ft. for liquids and solids, 10 ft. for bulk solids with high accuracy (±0.25%).
  • Durable Construction: Built with ABS housing and UV inhibitors, rated NEMA 4X for environmental protection.

How does the IRU-2000 ultrasonic sensor work?

The IRU-2000 uses ultrasonic transducers to emit sound waves that bounce off objects. By measuring the time it takes for the sound waves to return, the sensor determines the presence, absence, or distance of an object.

The IRU-2000 series offers multiple output configurations:

  • IRU-2002: Solid-state relay output
  • IRU-2003: Isolated 4-20mA output
  • IRU-2004: RS-485 with 1 NPN trip point

Yes. The IRU-2000 features a NEMA 4X-rated ABS housing with UV inhibitors, making it durable for outdoor and harsh industrial environments.

The IRU-2000 is designed for surface mounting, which eliminates the need for threaded fittings and allows for easy installation on walls, ceilings, or flat surfaces.

Each model comes standard with a 6-foot cable for easy installation and connectivity.
