Control Knobs & Levers

Elesa permanent magnets offer a simple way of providing temporary fixing for workpieces, instruments, gauges, covers, doors, signs or drawers. They offer a range of closure from low to extremely high adhesive force in a very small footprint − giving easy manual placement or concealed closure if required. Temporary fixing with high power magnets can provide permanent solutions, quickly adjusted or removed completely.

For example, Elesa’s range of high quality permanent magnets in sintered hard ferrite, Aluminium nickel cobalt (AINiCo), Samarium cobalt (SmCo) and Neodymium iron boron (NdFeB) are structured to have one adhesive surface only with poles optimized and arranged in such a way that the whole magnetic energy is focused on the adhesive surface. The effect in the area of the magnetic field is limited by a shielded system, avoiding the magnetization of the surrounding objects.

Neodymium magnets are ideal for location and temporary fixing of workpieces or panels or for sensor holding, e.g. on conveyors or other machinery. Moving down the scale applications can be as varied as supermarket labelling, locating presentation materials, white boards, cabinet door closure or magnetic filtration, e.g. of metal particles in engine sumps or in machinery and equipment.

These high quality permanent magnets are available in flat format with or without, steel or stainless steel housings in lacquer or thermoplastic coating and in cylinder format with brass housed sandwich configuration. U Magnets and cylinder magnets in red lacquer with pass-through facility are also part of the standard series.

Fluted or lobe-shape clamping knobs are available from Elesa UK in different materials, technopolymer, phenolic-based Duroplast, aluminum or stainless steel, for applications in many industrial sectors. A variety of shapes and diameters with plain, tapped bosses or with studs are available with standard threads to fit the application.

Clamping knobs from Elesa UK include:
- three arm knobs

Handwheels and crank handles are available from Elesa UK in technopolymer or phenolic-based duroplast, aluminum or special stainless steel. There are two different types of handwheels: spoked or solid handwheels with or without handle. These types of mechanical components are used on machine tools or industrial machines where steering operations are necessary.

Other types of handwheels and crank handles available from Elesa UK include
- monospoke handwheels
- safety handwheels
- safety coupling bushes for handwheels
- handwheels for metal flanges
- four-arm handwheels
- three-arm handwheels
- two-arm handwheels
