A Design Engineer’s Guide to MENTOR's wide range of Control Knobs

MENTOR Plastic Knobs

High Quality Control Knobs & Accessories

Turning, pushing, adjusting, controlling and displaying. An electronic knob has to perform many challenging tasks and depending on the application there are also design, temperature-resistance and weather-resistance requirements to consider, along with ease-of-installation and cost-effectiveness. In addition to MENTOR’s standard Knob ranges, their modular Knob Systems can be fully utilised to provide the level of customisation required by the application.

Wide Range of Variants

MENTOR offers a very wide range of control and adjusting knobs. In addition to knobs made of plastic, aluminium and chromed brass, the ranges also include digital and analogue turning knobs, aluminium wing knobs and complementary accessories. A range of material options and fixings are also offered for MENTOR's electronic knobs, for example different plastics, with a choice of collet or setscrew fixings.

Standard products and Custom solutions

Many standard products are available off-the-shelf with short delivery times and low MOQs. Implementing customised solutions is one of MENTOR's core competencies - alternative shapes, colours, radii and dimensions are all possible. Experienced product developers will work with you to find the best engineering solution combined with cost-effectiveness.

Samples available

It is difficult to articulate or illustrate on a web page how the high quality finish and tactile qualities of German-manufactured MENTOR knobs can transform users’ perception of a product. Please contact Multitron to request samples, so you can judge this subjective issue for yourself.
