Connector Solutions for Space Saving in Small Devices

As modern computing devices continue to become more portable for ease of use and convenience, they are simultaneously incorporating more advanced functions and features. These new additions, such as 5G wireless communication and multiple sensors for collecting information, require more components to be housed in what are very compact devices.
Based on these trends, JAE has introduced connector solutions that save space while adding new connector features and capabilities.

Small Devices and Compatible Connectors

Typical Connector Usage Examples for Small Devices

Below are examples of common connector usage in small devices.
Modern small devices have a limited amount of space inside, so it is important to keep components as small as possible. Depending on the mounting location, the connector footprint and height are essential to allow engineers the ability to stay within their desired package size. The connectors provided by JAE meet these requirements for size reduction while maintaining high reliability and ease of handling.

Connector Line-up for Small Devices

JAE offers a wide variety of connectors ideally suited for small devices.
The entire manufacturing process for these connectors, which have contact pitches between 0.2 and 0.5mm, are performed in-house, including the molding, stamping, plating, assembly, inspection, and packaging processes. It is critical that these processes are closely controlled in-house in order to achieve stable quality and connector specific manufacturing innovation.
We are able to deliver extremely high volume production while maintaining high-quality by using advanced automated equipment for connector assembly, video inspection, and embossed tape and reel packaging.

Connectors for External Interfaces

As a leading connector manufacturer, JAE was a contributing member of the working group which created the USB Type-C™ connector standards. We have a wide variety of connector and cable options that meet all of the requirements in the USB Specifications.
