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, ø36 mm and ø46 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.

ARE OFF-THE-SHELF OPTICS ALWAYS THE BEST SOLUTION? A
white paper from Resolve Optics addresses the commonly asked question ‘Are off-the-shelf optics always the best solution?’. For mass market applications where unit cost is the driving force there are a dizzying array of off-the-shelf lenses available. However, when it comes
to an application that optically requires anything a little more demanding such as leading-edge performance, high-resolution, compactness or a large image format then adopting an off-the-shelf lens typically will force you to accept a compromise in one or more of these important aspects. This can result in substandard results or at the cost of your optical product failing to make an impact in a competitive marketplace.
