The Pepperl+Fuchs UB400-F77-E2-V31 Ultrasonic Direct Detection Sensor is engineered to deliver precise and reliable object detection in compact applications where optical sensing technologies may fall short. With its ability to detect a wide range of target materials, including transparent, glossy, or irregularly shaped objects, this sensor is ideally suited for automation environments where versatility and consistency are critical.

At the core of the UB400-F77-E2-V31 is its adjustable ultrasonic sensing range of up to 400 mm, which ensures dependable performance independent of material color or surface reflectivity. This makes it particularly valuable in industries such as packaging, food and beverage, logistics, and material handling, where conventional sensors can struggle with reflective films, shrink-wrap, or dark surfaces.

The sensor’s rugged cubic housing, rated to IP67 protection standards, allows it to be deployed confidently in environments where dust, moisture, and temperature fluctuations are common. Despite its compact dimensions, the unit provides reliable detection in space-constrained setups, fitting seamlessly into conveyor systems, robotic cells, and small machine compartments.

Electrical integration is simplified through the 4-pin M12 connector, which ensures a standardized and secure connection. This not only reduces installation time but also supports plug-and-play compatibility across a wide variety of control architectures. The inclusion of an NPN switching output provides straightforward electrical interfacing for direct communication with PLCs and other automation controllers.

A standout feature of the UB400-F77-E2-V31 is its teach-in function, which allows users to quickly set the desired switching points without the need for complex programming. This user-friendly adjustment capability saves time during commissioning and makes the device adaptable to different production requirements with minimal effort.

By combining robustness, precision, and ease of use, the Pepperl+Fuchs UB400-F77-E2-V31 provides an excellent solution for challenging sensing tasks where reliability cannot be compromised. Whether it is detecting the presence of transparent bottles on a filling line, monitoring parts in a robotic cell, or ensuring accurate object positioning on conveyors, this ultrasonic sensor consistently delivers the performance demanded by modern automation systems.
