"Ultra-thin coaxial cable connectors" are widely used in small devices and in areas where high-speed signals are transmitted. "Ultra-thin coaxial cables" are extremely thin cables, comparable to a hair, yet each one has a coaxial structure. Due to their coaxial structure, they excel in transmission characteristics, flexibility, and torsional resistance. For example, they are mostly used for connections in critical parts of devices, such as the image sensor of a camera. They are effective when wiring in tight spaces or in areas that require repeated twisting. *For more details, please refer to the PDF document or feel free to contact us.*

The "half-pitch connector" is a product that has been on the market for over 30 years and is primarily used in industrial equipment. Half-pitch refers to the pin spacing being half that of full pitch (2.54mm pitch), which is 1.27mm pitch, hence the name half-pitch. The adoption of inches is said to be due to the fact that connectors originated in the United States. However, recently, the world standard of millimeters (mm) has become the basis. Full pitch connectors are often standardized products like DIN or MIL, while half-pitch connectors tend to be more proprietary products from various companies. *For more details, please refer to the PDF document or feel free to contact us.*

Various features have been incorporated, such as securing a suction space for automatic mounting (the plug-side connector comes with a pickup cover), resulting in a user-friendly product. The number of poles is available in direct connection with 52, 120, 140, and 160 poles, and in stack connection with 60 and 140 poles. As part of the family of products, a 0.635mm pitch flat cable dual type, the 8622E series, is also available, allowing for combinations with board-to-board connectors. This product serves as a next-generation connection solution, capable of meeting a wide range of needs in industrial equipment.

This is a 1mm pitch SMT connector that enables even higher density mounting from a harp pitch connector. Similar to half-pitch connectors, it allows for three-dimensional connections in horizontal, vertical, and stacked configurations, and offers a wide range of pin count variations from 30 to 120 pins. The receptacle side is equipped with a buckling prevention mechanism, achieving a stack connection height of 5mm and a mounting height of 4.8mm for horizontal connections, resulting in a compact and low-profile design. The straight type is designed with automatic mounting in mind, featuring a suction pad, while the right-angle type provides ample suction surface on the top.

The DJ series is a 1.0mm pitch two-piece connector developed as a next-generation removable connector. This series features a straight-type SMT connector on the unit side and a flexible light angle DIP type on the PC side, allowing for free selection of alignment (four types). It has a user-friendly design with careful considerations such as a guide mechanism effective for removable mating, a contact buckling prevention mechanism, the adoption of fixing hardware to enhance strength, and a reverse insertion prevention mechanism. It is a hot-swappable product that allows for the insertion and removal of HDDs, CD-ROMs, batteries, etc., while the power is on, and it enables the connection of frame grounds between devices. Additionally, a version with independent power pins on the left and right for effective power supply to battery packs is also available, making it an ideal product for removable applications.

The 89 series is a half-pitch low-profile connector with a follow-type single-point contact concept. It is the smallest and lowest-profile type among half-pitch connectors, equipped with a guide mechanism and compatible with SMT (Surface Mount Technology). This product is the SMT-compatible version. By attaching fixing brackets on both sides, it reduces the load on the contacts. The stack height is available in 7mm and 8mm, and there are eight variations in the number of contacts, ranging from 20 to 120 contacts.

The 89 series is a half-pitch low-profile connector with a follow-type single-point contact concept. It is the smallest low-profile type among half-pitch connectors, equipped with a guide mechanism and capable of SMT compatibility. It has become the de facto standard product for removable applications in laptops. Additionally, the right angle version features a three-row contact tail designed for high-density mounting. Five stack heights are available from 7 to 12 mm, and eight variations of pin counts are offered, ranging from 20 to 120 pins, allowing for a wide range of needs to be met. Of course, three-dimensional connections in horizontal, vertical, and stacked configurations are also possible.

The 89 series is a low-profile half-pitch connector with a follow-type single-point contact concept. It is the smallest and lowest profile type of half-pitch connector, equipped with a guiding mechanism and capable of SMT compatibility. This product is the flexible stack type "8903N-FS series," which has the same shape and dimensions as the "8903 series." Since it is based on the highly regarded "8903 series" in the market, it can be directly mated with connectors that were compatible with the 8903 series (8913-□□□-178S□-□, 8913-□□□-178MS□-A, 8930E-□□□-178MS, 8931E-□□□-178□). Standard stack heights are available in 20, 22, 24, 26, 28, and 30mm, but we can flexibly accommodate heights between 20 and 32mm, so please feel free to contact us.
