OKW’s 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 suit measuring/control, healthcare, HVAC, communications, building management and smart factory applications.
The knobs feature click rotation and push for ‘OK’ functionality. They are comfortable to operate and the surface-mount version tapers slightly towards 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: 33 and 41 mm diameter. Each unit comprises three parts: an assembly kit, knob and cover. They are moulded from PA 6 and PC (UL 94 HB). The standard colours are volcano, nero, diamond, emerald and sapphire.
