Ultrasonic sensors with analog output or digital output

Ultrasonic sensors

Non-contact distance & level Independent of color/surface Reliable in dust/mist

Balluff ultrasonic sensors are engineered for a broad range of applications—measuring fill levels, heights, sag, and detecting positions or objects in solid, powdery, and liquid media. They are a strong choice when you need dependable results regardless of color, surface finish, or environmental influences such as haze, dust, or impurities.

With digital and analog output options, high resolution, and small blind zones, these sensors support precise, non-contact detection and counting. Multiple voltage/current output variants—plus versions with additional switching outputs—help you match the right signal set to your control concept.

Which series are available (and how do I compare them)?

Below is a practical overview of common Balluff ultrasonic sensor series—covering design, range, interface/outputs, and connection/housing basics.

Note: “Blind zone” is the close range directly in front of the sensor where stable measurement is not possible—smaller blind zones help when space is tight.

Series	Design	Range (min–max)	Interface / Outputs	Connection / Housing
Cylindrical version with M12 thread (S-BUS M12) Analog output versions	Cylindrical	20–350 mm	Analog, voltage / Analog, current	Connector, M12x1 (Male), 4-pin Nickel-plated brass
Cylindrical version with M18 thread (S-BUS M18) Analog or digital output versions	Cylindrical	25–1300 mm	IO-Link; Analog (V/I); PNP/NPN	Connector, M12x1 (Male), 5-pin Brass / Nickel-plated brass
Cylindrical version with M30 thread (S-BUS M30) Long-range variants	Cylindrical	30–8000 mm	Analog (V/I); PNP; NPN	Connector, M12x1 (Male), 5-pin Brass / Stainless steel
Square version (S-BUS Q62) Wide range, multi-interface	Square	350–8000 mm	IO-Link; Analog (V/I); PNP/NPN	Connector, M12x1 (Male), 5-pin PBT
Cubic version (S-BUS R06) Compact housing	Cubic	20–1000 mm	Analog (V/I); PNP; NPN	Connector, M8x1 (Male), 4-pin ABS
Cylindrical version with angled sensor head (S-BUS W18) Angled head for installation flexibility	Angled head	25–1300 mm	IO-Link; Analog (V/I); PNP/NPN	Connector, M12x1 (Male), 5-pin Brass

Selection guidance: choose the measurement task (level/distance/object), then match range and output (analog voltage/current, IO-Link, PNP/NPN). Finally confirm housing shape and connector type for your installation.

Where are ultrasonic sensors used?

Ultrasonic sensors are ideal for non-contact measurement and detection when surfaces vary, colors change, or environmental conditions (dust, haze, mist) make other principles less reliable.

Typical applications

Fill level monitoring in tanks, containers, and hoppers
Distance/height measurement (e.g., stack height, position checks)
Object detection and counting on conveyors
Detection in powdery or dusty areas where optical sensors struggle

Why teams choose Balluff ultrasonic variants

Universal sensing independent of color and surface finish
High precision via high resolution and small blind zones
Flexible integration with analog and digital/IO-Link options
Robust performance in mist, dust, and dirt

Short definition: An ultrasonic sensor measures distance without contact using sound waves—well-suited for reliable detection in changing surface and environmental conditions.

FAQ: Balluff ultrasonic sensors (analog or digital output)

Quick answers to help you select the right ultrasonic configuration.

Analog models provide a continuous signal (voltage or current) proportional to distance/level. Digital/IO-Link models can deliver switching signals (PNP/NPN) and, with IO-Link, transmit measurement values and parameters digitally for diagnostics and easy setup.

Ultrasonic sensing is typically independent of color and surface finish, making it useful for targets where optical sensing can be inconsistent.

The blind zone is the close-range area in front of the sensor where stable measurement cannot be guaranteed. Sensors with small blind zones help in compact machines and close-up detection tasks.

Balluff ultrasonic sensors can be used for position/object detection and measurement in solid, powdery, and liquid media—supporting tasks like fill level monitoring, distance measurement, and object counting without contact.
