The ultrasonic sensor UC-F77 combines multiple functionalities in a robust housing design.

Ultrasonic sensors from Pepperl+Fuchs are a permanent fixture in the field of industrial automation. With the new UC-F77 series, you can now enjoy the advantages of the technology combined with an unparalleled range of features and adjustment options. This ultrasonic sensor can provide a flexible solution for many applications.

"During the development of the UC-F77, it became clear to our team that we were creating a real powerhouse! It's nearly impossible to bring together more functions and performance in such a compact design," reports Product Manager Carsten Heim. This "powerhouse" is available in standard or side-looker models. In both versions, the sensor is as small as its detection range is impressive—at 31 mm high, it can detect objects at a distance of up to 800 mm.


Minimal deadband for reliable short-range detection

Even at close range, the sensor stands out due to its special capabilities, according to Heim: "It has an extremely small deadband, meaning even objects in close proximity to the sensor are reliably detected." In addition, the switch points, output mode, output logic, and the sound beam width can be easily adjusted directly on the sensor using the programming button. Due to this interplay of performance over short and long ranges, a compact design, and extremely high adaptability, the F77 is suitable for universal use in a wide variety of applications.


Advanced sensor functionalities ensure highest process safety

Another competitive aspect is its phenomenal process reliability: in addition to precisely adjusting the sound beam on the device itself or via PACTware™ software, users can also accurately suppress echoes from false targets. The F77 is also the only sensor of its size to offer automatic synchronization. This means that there can be up to ten sensors in operation in the same cycle or in multiplex mode without external intervention. This prevents cross-talk between sensors that are mounted within close proximity of each other and ensures the shortest possible response time.



Automatic synchronization allows the operation of up to ten F77 ultrasonic sensors in close proximity of each other—without crosstalk.

Quick commissioning with IO-Link integration

Rounding off the broad range of functions is IO-Link integration, which enables quick commissioning via the control panel and reveals valuable diagnostic data. "Being versatile is the specialty of the F77. It is aimed at users who want to handle the largest possible range of applications with a single type of ultrasonic sensor—and in doing so expect the finest granularity when it comes to adjustment options," states Heim.


At a glance
