Collet knobs now in flush-fit and surface-mount versions

OKW’s advanced STAR-KNOBS for menu-driven electronics are now offered in flush-fitting and surface-mount versions.

These ergonomic collet knobs fit rotary potentiometers or rotary pulse generators with round shaft ends (DIN 41591). They are excellent for measuring and control, healthcare, HVAC, communications, building management and Smart Factory technology.

The devices feature click rotation and push for ‘OK’ functionality. They are comfortable to operate; the surface-mount version tapers slightly towards the inner axis. All the knobs can be specified with or without knurls and/or a finger recess in the cover.

Both versions offer optional LED illumination. Flush-fitting knobs can be specified with a ring that lights up between the recess and the knob cover. The surface-mount version sits on a 3mm high ring that can be illuminated.

Two sizes are available: ø33mm and ø41mm. Each unit comprises three parts: an assembly kit, a knob and a cover. They are moulded from PA 6 and PC (UL 94 HB). The standard colours are volcano, nero, diamond, emerald and sapphire.

Two 5V energy-saving SMD LED illumination kits (accessories) are available, either white or RGB. Other accessories include assembly supports, round nuts and a box spanner.

The company can supply STAR-KNOBS fully customised. Services include CNC machining, lacquering, printing, laser marking and installation/assembly of accessories.
