Customised rotary potentiometer and encoder knobs for menu-driven interfaces
OKW's award-winning CONTROL-KNOBS for rotary potentiometers and encoders can now be specified customised and 'production line ready'.
These ergonomic knobs, which won an iF DESIGN AWARD, are ideal for touch/click functions on menu-driven interfaces. Applications include measurement and control, medical/wellness, laboratory equipment, HVAC, communications, building control systems and Smart Factory technology.
CONTROL-KNOBS can now be specified custom machined and printed with legends, logos and graphics. OKW can also supply the knobs with laser marking - perfect for consecutive numbering or machine-readable QR codes, bar codes and DataMatrix codes. Other customisation services include installation/assembly of accessories.
These ergonomic collet knobs combine a robust polycarbonate inner body with a soft-touch TPE outer shell for anti-slip operation. Functional grooves on the edge ensure a good grip.
CONTROL-KNOBS can be specified (as standard) with or without a pointer line on the side for fine scaling. Optional LED illumination and a translucent optic ring enable operation in low light conditions and further enhance the aesthetics. Energy-saving (5 V) SMD RGB LEDs allow individual illumination and colours.
The knobs are available in two diameters, 36 mm and 46 mm - both for 6 mm, 1/4" (6.35 mm) boreholes - and in two standard colours: nero and volcano. Top covers and bases (accessories) can also be specified in these colours. Accessories also include round nuts and a spanner.
The minimum component specification for one CONTROL-KNOB without illumination is a knob and cover; a base can be added if required. A base and illumination kit (accessory) are essential for the LED backlit version. On request, OKW can supply the knobs with accessories pre-assembled.
