Hirose – Shorter USB Type-C receptacle saves space in densely populated board layouts


Hirose has developed a mid-mount USB Type-C receptacle which offers a compact footprint to save board space.

The new CX series connector, which conforms to the specifications of the USB 3.1 standard, is only 8.35mm deep. By comparison, conventional USB Type-C connectors are longer, up to 9.4mm. The use of the new smaller connector frees up space in board layouts which can be used to accommodate for instance a larger battery or antenna.

The connector features a hybrid design, using both surface-mount and through- hole soldering to minimise the board mounting space needed.

The design also facilitates automated optical inspection and eases reworking of the solder terminal joints with a visible lead design.

The receptacle is user-friendly and features a symmetrical mating face to allow insertion of a reversible plug. Use of a reversible plug eliminates the risk of incorrect insertion.

The CX series receptacle supports data- transfer rates up to 5Gbits/s.
