OKW: Potentiometer tuning knobs that are highly comfortable to operate

New ergonomic CONTROL-KNOBS have a soft-touch surface which is easy to grip and feels comfortable in operation. The high-quality appearance – illuminated if required – distinguishes this advanced range of tuning knobs as the central element of menu-driven interfaces.

  • soft-touch surface ensures good grip and anti-slip operation
  • innovative two-part plastic tuning knob design comprises a hard inner knob body
    made of high-quality PC and a soft-touch TPE outer shell with functional grooved appearance
  • available in two knob sizes, ø 36 mm and ø 46 mm, each in two standard TPE colours (nero and volcano)
  • CONTROL-KNOBS with/without pointer line on the side for fine scaling
  • CONTROL-KNOBS with/without optional LED illumination
  • illumination options:
    – translucent optic ring on the top surface
    – translucent optic ring on the top surface with a pointer line on the side
    (note: order the CONTROL-KNOBS with optional illumination,
    plus the base and the LED illumination kit, see accessories)
  • optional illumination uses modern, energy-saving SMD LED technology
    for 5 V power supply units (RGB LEDs allow individual illumination and colours)
  • designed as modern control knobs for rotary potentiometers or encoders;
    also suitable for rotary touch/click functions used on menu-driven interfaces –
    typically employed on devices made in high volumes
  • tried and tested collet fixture system with secure fit on the axle
  • max. torque: installation = 1.5 Nm, function = 1.2 Nm
knob sizes boreholes
ø 36 mm 6 mm, 1/4″ (6.35 mm)
ø 46 mm 6 mm, 1/4″ (6.35 mm)

Minimum components for one CONTROL-KNOBS, without illumination:
1 CONTROL-KNOBS, 1 cover – the accessory base can also be added if required

Minimum components for one CONTROL-KNOBS with LED illumination:
1 CONTROL-KNOBS, optional illumination, 1 cover, 1 base, 1 LED illumination kit (RBG backlight)

Designer Statement

“Perfect all round – modern tuning knobs which are pleasant to the touch, with which processes can be reliably regulated or controlled and which should have a fixed place in the user interface of a modern product. When it comes down to it, these tuning knobs can ensure easy operation of your products even in awkward places and under adverse conditions – robust in appearance and precise in their function. You will find the CONTROL-KNOBS easy to use. The illuminated lines indicate the location, status and position of the function you are looking for. With or without gloves, the haptic structure and the pleasant material of the grip surface reliably apply the necessary torque to the knob axle – in any application situation.”
