USL Series of I.D.C. connectors provides support for 0.4-mm pitch, ultra-fine coaxial cables (#42 AWG) and makes full use of KEL`s technical expertise in batch assembly for the purpose of cable connection.

During the development process, considerable effort was placed on the perfecting of a series of connectors that – particularly in terms of data-transmission – would minimize the degree to which the beneficial characteristics of the coaxial cable were affected. encasing the board-side connector in a metallic shell, we achieved simultaneous improvements in noise resistance, component strength, and grounding performance.

The connectors of this series have a pitch of 0.4 mm and a low mounting height of 1.0 mm.

When compared with our current SSL Series of connectors for 0.5-mm pitch, ultra-fine coaxial cables, the USL Series achieves a major reduction of approximately 50% in terms of coupled volume, thus contributing greatly to weight reduction and device miniaturization. This product features a right-angle type connector on the board side and a straight type on the cable side; furthermore, 30- and 40-contact variations are currently available.
