BOS 6K sensor family in new generation
Innovative, Versatile, User-Friendly
The BOS 6K optoelectronic sensor family consists of cubical midi sensors that cover all relevant detection principles and use different light sources for this purpose. The latest generation convinces with proven, but also completely new functional principles and technologies that meet even more applications in industry and production.
What all sensors in the family have in common is their housing shape, their operating concept and the IO-Link communication standard. This uniformity considerably simplifies the parameterization and integration of the sensors and improves their usability. In combination with the intelligent PNP/NPN output, this also reduces the number of variants required.

Precise, fast and high range: BOS 6K sensors with Time-of-Flight technology
In addition to the standard red light and laser variants, Balluff also offers sensors equipped with Time-of-Flight (TOF) technology for long-distance sensing. They are capable of detecting objects safely and reliably at longer distances, despite their small housing.
Their Time-of-Flight technology sends light pulses and measures the time they take to travel to the object and back. This is particularly advantageous for background suppression, as it means that even a background close to the object can be reliably distinguished from the object and the distance precisely measured.
Multi-talented sensors with Time-of-Flight technology
The time-of-flight method also works reliably at greater distances, which means that the sensors can be used for distances of up to 1.5 m despite their compact design. This opens up completely new possibilities in the design of automation systems and makes the sensors very flexible to use. These sensors achieve significantly better performance with a much smaller design than was previously possible with considerably larger sensors.
Another major advantage of TOF sensors is their versatility: they can be used in different environments, as they work largely independently of the surface and color of the object. They reliably detect both light and dark surfaces.
When red light sensors reach their limitations: BOS 6K photoelectric sensors with blue light technology
A highlight of the new generation is the availability of sensors with blue light technology for background suppression, which makes them ideal for reliably detecting transparent and similarly tricky objects.
The use of sensors with blue light is particularly recommended in applications where red light reaches its physical limits.

Easy detection of hard-to-see objects
Since blue light has a shorter wavelength than other colors of visible light, it scatters less and the light beam is better focused. The lower scattering means that blue light sensors can detect finer details and, depending on the application, work even more reliably than their red light counterparts.
In addition, blue light penetrates less deeply into materials compared to other light wavelengths. This minimizes interference with other objects and surfaces and makes object detection even more precise.
Blue light makes it easier to recognize certain features or properties of objects. Even difficult materials or surface textures, for example in the case of transparent or dark and shiny objects, are detected more reliably than would be possible with red light.
