Types of Ultrasonic Sensors

Cubic sensors—versatile in respect of design and application

The series L2 ultrasonic sensors feature both a large range spectrum and a rotatable sensor head.

Our broad cubic sensor portfolio offers the ideal solution for almost every measuring task. Special designs and features such as minimized blind zones, large ranges, and extremely rugged designs open up maximum flexibility in application solutions for the user. Series F77 ultrasonic sensors offer a wide range of features and setting options such as IO-Link, sound beam switch, synchronization, minimal blind zones, and a high range of up to 31 in. Series F12 ultrasonic retroreflective sensors are ideal for measurements in especially small feedings such as in bottling machines or in shaking conveyors, while ensuring the highest degree of detection reliability by means of independent sensor synchronization. The series L2 ultrasonic sensors feature both a large range spectrum and a rotatable sensor head, enabling special installation options. With IP67 protection, they are ideally suited for use in harsh environments. Depending on the intended use, there are additional cubic designs available.


Cylindrical sensors—maximum flexibility for diverse applications

Chemically resistant ultrasonic sensors

Hygienic sensors—for use in product-contact zones


Double sheet sensors—safe process operation and high plant availability


A multilayer feed of materials such as paper, cardboards, sheets, foils, or labels can lead to machine downtime, process disruptions, and waste. Double sheet sensors prevent defective material feeding und ensure safe processes and high plant availability. This technology is applied as double sheet, label, and splice control.
