Next generation of BOS 6K with Ecolab approval

The new generation of photoelectric sensors in the BOS 6K series from Balluff is setting new benchmarks in the compact class. Its small 31.5 × 19.5 × 10.8mm dimensions make it useful in tight spaces in compact machines. Its 70 variants provide a functional product range from start to finish, with red light and laser versions (class 1) for very demanding jobs. The range features impressive precision, range and function reserves. Diffuse sensors, through-beam sensors, reflection light sensors with and without background suppression and analogue distance sensors, each with the flexibility to be configured for light/dark switching, are just a few examples from the BOS 6K family.

All of the sensors have a tough and durable plastic housing with abrasion-resistant laser inscription. A special design element protects the optics from the side. Thanks to its particularly high IP 67 & IP 69K degrees of protection, a lens surface of PMMA and Ecolab approval, the BOS 6K is also a prime choice for use in the food industry.

All of the variants feature high-quality teach buttons with excellent tactile feedback. If the installed sensor is difficult to access, they can also be taught whatever the aspect of interest is using a remote connection. The sensor functions can also be configured during ongoing operation. Two LEDs, easily visible from any direction, provide information at a glance. They indicate the operating state, the function reserves and the switching state. Very durable metal plugs ensure there are no outages under high mechanical loads.

Switching from an earlier model to the new BOS 6K generation is straightforward for the user. The size, installation, operating concept and even the price are identical. This means that the user gets even more performance for the same price.

The retroreflective light sensor with autocollimation is a particular highlight. Thanks to its very low hysteresis, it easily detects transparent objects made of glass, such as bottles, ampules or test tubes, or transparent plastic films. As analogue distance sensors, BOS 6 sensors open up new possibilities, such as for positioning clamping jaws on a machine for producing ball bearings.

Installing the BOS 6K is easy: two integrated dovetail guides on the housing as well as two normal drilled holes and two elongated mounting holes offer a high level of freedom for mounting.
