Ultrasonic Sensors
Ultrasonic sensors are non-contact measurement devices that use high-frequency sound waves (typically between 20 kHz and 400 kHz) to detect the presence, distance, or level of an object. They operate on the principle of time-of-flight (ToF): the sensor emits an ultrasonic pulse and measures the time it takes for the echo to return after reflecti...
Ultrasonic sensors are non-contact measurement devices that use high-frequency sound waves (typically between 20 kHz and 400 kHz) to detect the presence, distance, or level of an object. They operate on the principle of time-of-flight (ToF): the sensor emits an ultrasonic pulse and measures the time it takes for the echo to return after reflecting off a target. Key technical parameters include sensing range (from a few centimeters up to several meters, depending on the model), beam angle, resolution, and frequency. These sensors are available in various housing styles (cylindrical M12, M18, M30, or rectangular) with different output types such as analog (4-20 mA, 0-10 V), digital (PNP/NPN), or IO-Link for advanced diagnostics and parameterization. They are also known as ultrasonic proximity sensors, ultrasonic transducers, or sonic sensors in different markets worldwide.
Ultrasonic sensors are widely deployed in industrial automation for object detection, distance measurement, and level monitoring. Common applications include presence detection in conveyor systems, fill-level measurement in tanks and silos (liquids, granules, powders), collision avoidance in mobile robotics and AGVs, loop control in web processing, and counting objects on production lines. They are particularly valued in environments with dust, steam, or light interference where optical sensors may fail. Typical installation environments include packaging lines, water and wastewater treatment plants, food and beverage processing, automotive assembly, and material handling systems.
Our portfolio includes several subcategories of ultrasonic sensors tailored to different applications. Key article codes include the OM2601 series (cylindrical M18, 30-300 cm range, analog output), OM2602 (M30, 50-500 cm, PNP/NPN), and OM2603 (rectangular, 20-200 cm, IO-Link enabled). The code structure typically follows the pattern OM26XX, where the first two digits indicate the series and the last two specify the range and output type. For example, OM2601 indicates a standard M18 sensor with a 300 cm range and analog output. We also stock diffuse and retro-reflective ultrasonic sensors, as well as models with teach-in functionality for easy setup.
