Extra small designs for tight conditions


Industrial automation requires increasing miniaturization of assemblies. This requires components that are small and light, yet also as powerful as possible. Miniature sensors from Balluff meet these demands.

Through mini-designs with maximum performance, they provide a great degree of design freedom to make many applications possible. For you this means added flexibility. Balluff provides mini-sensors with all operating principles: Inductive, photoelectric, magnetic, capacitive and ultrasonic. Compact inductive couplers, space-saving fieldbus modules and RFID in mini versions are available for each sensor technology.

Our products include mini-sensors and compact connection technology, both excellent for factory automation. Particularly in robotics, on production lines or in handling applications, for example, low weight is the key requirement for fast cycle times. Moreover, the space saved by the compact design provides greater room for maneuvering in a tightly packed work space.

Miniature sensors from Balluff guarantee high precision and ensure the necessary reliability.

Inductive mini-sensors

Powerful and compact for position sensing in rough environments
Inductive mini-sensors guarantee position sensing in rough environments and in the tightest of spaces. This is because their electronics are fully integrated, making external amplifiers unnecessary.

Their low weight of 0.7 g permits applications with extreme accelerations. Pick-and-Place is easy to achieve as a result.

Inductive mini-sensors from Balluff are easy to install and can also be fully integrated into slim assemblies. As a result, using them for position sensing is possible where there had never been space for a sensor before. And assemblies can be further reduced in size. Balluff provides mini-sensors with particularly small diameters: 3 mm, 4 mm and 5 mm. With a housing length of only 6 mm, our compact mini-sensors are the shortest inductive sensors on the market.

Photoelectric mini-sensors

Detect small parts at a distance of up to 3 m with precision
Photoelectric mini-sensors from Balluff are the right choice if small parts need to be detected in limited space with precision and long ranges are important. This is because they work absolutely reliably from less than one millimeter to distances of up to three meters.

With their wide range of product variants, they are a reliable solution to all applications and offer a great degree of freedom in design. Advanced laser technology, homogeneous red light or innovative pinpoint technology stand for high process accuracy. Diffuse sensors with background suppression reliably eliminate interfering influences. And our photoelectric mini-sensors are extremely easy to operate.

Capacitive mini-sensors

Detect all materials regardless of external influences and the properties of an object
Capacitive mini-sensors are the right choice for measurement in difficult environments where dust, reflections or the properties and color of an object can influence the result.

They monitor stack heights and detect solids and liquids with extreme precision. They can sense through glass or plastic container walls up to 4 mm thick or in direct contact with the media. Fine adjustment of the capacitive mini-sensors is easily performed by means of a separate sensor amplifier. A Teflon® sensing surface makes them particularly resistant and their robust stainless steel housing makes use under difficult conditions possible as well. Due to the flat disk design, they require particularly little space and offer a large switching distance.

Ultrasonic sensors

Universal use for distance measurement and position detection
Our small ultrasonic sensors in a cuboid housing operate with a particularly high resolution and thereby deliver convincing performance with accuracy.

For challenging measurement tasks, BUS R06K1..02/007 and BUS R06K1..02/015 can additionally be equipped with a sound transmission attachment. This makes measurements in bore holes and openings having diameters greater than 5 mm possible. The BUS R06K1..02/015 impresses with a short delay time and high switching frequency of 125 Hz. It is thus ideally suited for reliably detecting fast processes.

The simultaneous operation of up to ten sensors in the tightest of spaces is also possible with our ultrasonic sensors. This is because the series has a synchronization input. The wide range of variants with switching output or with current or voltage analog output in five operating scanning ranges make the sensor family suitable for nearly limitless applications.

Magnetically coded position measurement system

Absolute measuring system for short strokes
Inaccuracy and tolerance shifts have a negative effect on production quality. Direct measuring systems solve this problem. They detect the current position directly on the carriage or the load support.

The magnetically encoded BML-S1H position measurement system from Balluff measures highly dynamic applications exactly and absolutely. And it operates without contact and is therefore non-wearing. External factors such as dirt or temperature do not pose a problem. With its unbeatably small sensor head, the system is ideal for linear guides, pick-and-place applications, drive feedback or vibration welding.

Compact inductive couplers

IO-Link coupler for fast, contact-free connection
The inductive IO-Link coupler from Balluff in the compact 40x40 housing is ideal for robotics. It combines rapid format changes, freedom of wear and great flexibility.

Mechanical plug connections are rendered superfluous with inductive couplers because they transfer these signals without contact. The IO-Link interface of the compact inductive coupler makes installation extremely simple. This is because IO-Link is quickly wired.
