Potentiometer knobs setting new standards in medical electronics

OKW's award-winning TOP-KNOBS for medical electronics are increasingly being specified by designers

With their unique styling, the knobs are also excellent for measuring and control, laboratory equipment, HVAC, communications and building management.

Each potentiometer knob comprises a main body with a clip-in marking element that hides the lateral fixing screw and allows fine calibration. There are five elements (Pin, Globe, Disk, Wing, Arrow) in a range of attractive pastel colours: coral (pink), beach (yellow), lagoon (green), sky (blue) and mineral (grey). The main knob body is available in either volcano (grey) or nero (black) as standard.

The knobs can be specified with either a push-on fixing (for potentiometer shafts with flattened ends) or a lateral screw (DIN 41591). The fixing method rules out any possibility of contact with live parts. The underside of each knob is recessed to include potentiometer fixing nuts.

The tuning knobs are moulded from PA6 in five diameters – ø16mm, ø20mm, ø24mm, ø31mm and ø40mm – for boreholes of 4mm, 6mm, 1/4" and 6/4.6 mm. Accessories include M7, M10 and 3/8"-32G round nuts for securing potentiometers to front panels.

The company can fully customise TOP-KNOBS. Services also include machining, printing, laser marking and installation/assembly of accessories.
