Connector Solutions

Connectors are used to connect devices or boards and transmit electrical signals at high frequencies and high speeds in a stable manner.
Yamaichi’s connectors are highly evaluated for their excellent specifications, durability, and supply capabilities based on Yamaichi’s mechanism design and evaluation technologies.
In particular, as the only manufacturer in the industry that handles both connectors and flexible printed wiring boards, Yamaichi can offer combination sets of these products. Yamaichi has the know-how and systems to respond to special applications (customization), which enables Yamaichi to meet the diverse needs of its customers and sometimes leads to the development of world-leading, innovative technologies.

Used in the following areas:


Yamaichi’s connectors are used for in-vehicle devices exposed to elevated temperature and vibration.

Production sites

Yamaichi’s connectors contribute to production efficiency and stability with their cable connection workability and retention force.

Communications infrastructure

Yamaichi’s connectors ensure stable connections of a wide variety of devices in data centers and base stations.

Representative Products

Interface Connectors for Optical Transceivers

Interface connectors are used to connect each communication network device to optical transceivers. The lineup includes connectors and mechanical components that comply with each multi-source agreement (MSA) standard. Interface connectors are used in wavelength division multiplexing (WDM) technologies, routers, ethernet switches, servers, and storage.

H001-series Coaxial Connectors for Automotive Cameras

This series offers a choice of a pigtail type or direct relay type. The connector mounted on the board on the camera side is one of the smallest in the industry, enabling the camera to be miniaturized. H001-series coaxial connectors are available for all kinds of in-vehicle cameras. Furthermore, H001-series coaxial connectors have a 4.0-GHz transmission characteristic, making it possible to use them in high-speed signal units with a large amount of information transmission, e.g., electronic toll collection (ETC) gates and the Global Positioning System (GPS).
