OKW’s advanced STAR-KNOBS for menu-driven electronics are now available 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 ideal for measuring and control, healthcare, HVAC, communications, building management and smart factory technology.

STAR-KNOBS feature click rotation and push for ‘OK’ functionality. They are comfortable to operate; theSource: OKW surface-mount version tapers slightly toward the inner axis. All the knobs can be specified with/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 3 mm high ring that can be illuminated.

Two sizes are available: ø 33 mm and ø 41 mm. Each unit comprises three parts: an assembly kit, a knob and a cover. They are molded from PA 6 and PC (UL 94 HB). The standard colors are volcano, nero, diamond, emerald and sapphire.
