Ergonomic tuning knobs with illumination options

30 March 2022 Switches, Relays & Keypads

With its new Control-Knobs range, OKW Gehäusesysteme offers an advanced range of tuning knobs as the central elements for menu-controlled interfaces. The soft-touch grip surface provides an easy hold, a pleasant touch sensation and ergonomic operation. The high-quality appearance can also be illuminated if required.

The modern-looking parts are designed for user-friendly utilisation and consist of hard and soft plastic components, with a knob body made of high-quality PC (UL 94 HB) and a soft-touch TPE outer shell with a functional grooved appearance. Thanks to the soft-touch material, the new tuning knobs offer high-grip qualities with an anti-slip effect.

Installation of the Control-Knobs is effected using collets which guarantee a secure fit on the spindle and are ideally suited for rotary potentiometers/pulse encoders with round shaft ends in accordance with DIN 41 591. For final assembly, a cover made of PA 6 (UL94) is mounted on the basic body. The knobs are available in the standard colours nero and volcano, with either 36 mm or 46 mm diameters.

Both sizes are available with/without a pointer line on the side for fine scaling. The tuning knobs can be fitted with energy-saving SMD LED technology to provide individual lighting customisation. In this version, the basic body of the knob is not traffic white, but is made of translucent material. This provides illumination options with a translucent optical ring on the top surface, or a translucent optical ring on the top surface with a pointer line on the side.

To illuminate the ring, the base available in the range of accessories is required, together with the LED lighting kit (RGB backlight). Applications include measuring and control engineering, medical field and laboratory technology, smart factories, communication and many more. To adapt the knobs to special customer requirements, they can be modified by means of printing or laser marking on the top surface/cover.
