Wave-X Heat, a new EMI absorber innovation from ARC Technologies is a range of heat-shrinkable tube absorbers available through Clarke & Severn Electronics .
Designed to integrate seamlessly with wire and cable assemblies, Wave-X heat-shrinkable absorber tubes neatly seal junctions and connector interfaces while absorbing unwanted EMI interference, which is a common problem with wires, cables and interconnects.
A traditional solution to counter EMI interference has been to install bulky, heavy and visually unattractive ferrite cores onto the cable and then over-mould the ferrite. Wrapping conductive tape over the offending cable or connection is another option.
Wave-X Heat is simply slipped over the cable or connector followed by application of heat for the absorber to shrink and conform appropriately.
Wave-X Heat heat-shrinkable absorber tubes incorporate an inner layer of thermoplastic polymer, blended in exacting ratios with magnetically permeable metal powders. The outer layer of the EMI absorbers is a high dielectric thermoset polymer.
When moderate heat is applied the product shrinks to approximately a 3:1 ratio.
