All the Screening Techniques that KEC has developed over many years of experience in this field are incorporated in the KC2000 range designed for a wide variety of EMC and environmental specifications including TEMPEST and IP66/67/68.

The KC2000 range uses state-of-the-art technology to provide the correct EMC solution no matter what the target specification and provides excellent value for money.

The range comprises eight individual products each designed to suit different EMC, mechanical and environmental requirements. The rationalisation of the product range has allowed us to use common parts within the different models. This means an increase in production flexibility and a reduction in piece stock part holding for our assembling distributors resulting in a high degree of economy and quick delivery for our customers.

Many customers have their preferred method of screen termination, from simple cable ties, to springs, band straps, clamps, and metal rings that respond to heat. 

IMG_2050 thumbnail.jpgIn some cases large investments have been made in the tooling to apply that screen termination.  For those customers the KC2500NS backshell is available without any screen termination device so that they can continue to use the termination method of their choice. The KC2700 provides a highly cost effective backshell solution for overall screening with reworkable band clamps that don’t require any special tooling or assembly skills that are easy and economical to install.  The KC2800 provides a complete solution for individual and overall screening with band clamp, interwoven braid and slotted backshell body. 

The IRIS spring technology in the KC2100 and KC2300 provides the highest levels of overall screen performance as the cable screen is not disturbed in any way. They are also perfect for fibre optic cables or a combination of fibre and copper. With the correct connectors and cables in the system protection levels in excess of 100dB over a wide frequency range can be achieved. Other products in the range utilise alternative methods of screen termination that rely on feeding the overall braid over a braid trap barrel or spigot of some form that with careful size matching can achieve excellent levels of screening.

The method of individual screen termination by interwoven braid is consistent throughout the range. The highest levels of performance and protection can be achieved without any of the drawbacks associated with solder sleeves, daisy chains or pigtails. Due to the simple mechanical method of assembly, production and re-work times are minimised.

The KC1100 is a heat shrink boot adaptor for use where no screen termination is required.  The spin-coupling adaptor is suitable for a wide range of standard circular connectors and a variety of cable entry size options ensures the best fit of the heat shrink boot for maximum cable strain relief. Strain relief clamp adapators are also available.
