Cable installation, with EMC shielding and grounding, simplified
Recent introductions to the icotek range of cable entry products, as available from M Buttkereit Ltd, include EMC shielding products, and split conduits which are suitable for even retro fitting of pre-terminated cables.
Electromagnetic compatibility (EMC) is becoming more important, with designers needing to consider the effect of radiated emissions polluting the environment as well as random electromagnetic fields penetrating sensitive electronic circuitry. The icotek type SKL shield clamps provide a simple and reliable connection to the appropriate layer (usually braided metal) within shielded cables, providing a universal answer for wherever shielded cables need to be connected with an installation mass potential.

The SKL shield clamps offer large-area contact with the cable shield layer once any cable outer layer has been removed. The prepared cable is simply pressed-in to position and positively retained under the constant clamp pressure which does not require any post-installation adjustment. Close grouping of cables can be accommodated, for both space saving and cost-effective installations.

The SKL clamps can also be supplied with optional mounting attachments to provide snap-in assembly on H shape, 35mm DIN rails, or bolt-on assembly for sub-plate mounting including a strain-relief version. They can be supplied suitable for cable shield layer diameters from 1.5 to 29mm, including a version designed for push-clip mounting to busbars size 10 x 3mm. Customised carriers can also be designed to order for specialised requirements including high density cable installations. Where earth grounding needs to be combined with cable shielding, the alternative SK range of clamps can be supplied for optional mountings including H & C DIN rails, busbars and sub-plates.

The WST range of split corrugated conduit can also be supplied, ideal for retro fitting of additional cabling including pre-terminated varieties. The conduit can be supplied in seven nominal sizes from 10 to 70mm diameter and in lengths of 10, 25 and 50 metres (smaller O/D sizes only). The material is halogen-free, UV-durable black Polypropylene UL-94 V2, and provides the maximum versatility for any stage of cable installation including both OEM and service-modified requirements.
