Whether blue light or time-of-flight, whether a proximity switch or distance measurement sensor, whether shorter or longer range, the cubic mini sensors of the BOS 6K optoelectronic sensor family from Balluff cover all relevant detection principles and a wide variety of light types.
The new generation of the family is more than just an upgrade. Thanks to IO-Link, innovative technologies and additional variants, it will be possible to serve even more and, above all, previously unsolved applications and detection tasks with this series in the future.
Diversity meets uniformity
With the BOS 6K sensor family, the user only needs a single sensor design for a wide variety of applications. This is because all relevant functional principles are available in the same, space-saving and universally mountable housing. This simplifies system design considerably, as only one CAD data set is required, which is identical for all sensor types. This saves a lot of time and effort during installation.
The equipment with IO-Link opens up completely new possibilities for parameterization and user-friendliness. Together with the uniform operating concept for all BOS 6K, this feature helps to put the sensors into operation quickly. It is also easy to exchange or switch between sensors in the family that use different operating principles.
A useful mix of updated and new variants
The new generation of the BOS 6K impresses with state-of-the-art technology and future-proof functional principles: Time-of-flight, blue light, red light, laser, distance sensing as well as contrast detection:
Precise, fast and high range: BOS 6K sensors with Time-of-Flight technology
Balluff now 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.
Easy detection of hard-to-see objects
The use of sensors with blue light is particularly recommended in applications where red light reaches its physical limits.
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.
The optical automation all-rounder
Optical sensors based on laser or red light are widely used in all areas of automation.
Red light is a reliable technology with a very good cost-benefit ratio, making it the light type par excellence for almost all standard applications. Its well-focused light spot, which is large and highly visible, makes the sensor easy to align, while its housing design makes it easy to mount and align.
Laser sensors are ideally suited for reliably detecting small parts such as wires, even when scanning at greater distances. This is ensured by the minimal diameter of the emitted laser beam. Due to its good visibility, the laser spot can be aimed to easily detects objects very precisely with high repeatability.
Special retro-reflective sensors for the detection of transparent objects are also part of the large BOS 6K sensor portfolio, as are powerful distance sensors with red light and, most recently, laser technology.
Reliable object detection at high speeds: BOS 6K contrast sensors
The BOS 6K contrast sensors are a reliable, flexible and simple solution for detecting contrasts. They can be easily connected to the controller via a standardized output. Parameterization is just as straightforward using IO-Link.
The sensors detect bright objects or markings on a dark background or vice versa, and do so largely independent of the object surface.
This and their extremely high switching frequency make them ideal for applications in which objects and markings must be detected precisely and, above all, quickly - for example, in packaging or labeling applications.
"Our robust BOS 6K sensors are easy to adjust – even with IO-Link – and cover a wide range of industrial applications with their variety of operating principles."
