Announcement of the development of the "DUS Series" floating connector with a 0.4mm pitch, supporting a low profile stack height of 3mm, featuring high-speed transmission, high heat resistance, and multiple poles.

Small Floating Connector 0.4mm Pitch Floating Connector DU Series

The DU series is a 0.4mm pitch floating connector. It achieves productization with the industry's smallest contact pitch of 0.4mm for floating connectors. When compared to our 0.5mm pitch floating connector DY series, the board space occupied is reduced by approximately 48% for the plug and about 31% for the receptacle. Despite the 0.4mm pitch, it allows for ±0.4mm movement in the XY direction, which can absorb assembly tolerance deviations in equipment. The mounting method is vertical direct connection. The contact area on the plug side has an arc shape, similar to the DY series, making it difficult to catch foreign objects. The receptacle eliminates terminal exposure on the bottom surface, preventing foreign object intrusion and allowing for pattern wiring at the contact bottom. The effective mating length of the DU series is 1.2mm, ensuring reliability during mating. The contact method is a contact cantilever type. The number of contacts can expand up to 200, compared to a maximum of 140 in the DY series. For 200 contacts, a compact design of 40.36mm in the longitudinal direction and 7.5mm in the width direction is achieved. The stack height is from 7mm. As a dust prevention measure, the receptacle side is equipped with Kapton tape for automatic mounting, sealing the mating port.

Not only can it absorb positional misalignment during fitting, but it can also accommodate positional misalignment after fitting due to rotation from tightening screws!

A "floating connector" is a connector equipped with a floating mechanism that absorbs vertical and horizontal errors that occur when mounting the connector onto a circuit board. By allowing the connector to move, it can absorb errors and misalignments during mating, preventing issues such as cracks in the circuit board. It is widely used in devices where circuit boards are densely packed, such as car navigation systems, digital cameras, and semiconductor control devices. 【Features】 ■ Equipped with a floating mechanism ■ Absorbs errors and misalignments during mating by allowing the connector to move ■ Prevents issues such as cracks in the circuit board *For more details, please refer to the PDF document or feel free to contact us.

• Board to Cable Connector

The connector's connection part is movable to absorb stress! It is widely used in both industrial and consumer equipment.

At KERU Corporation, we handle compact and high-performance "Floating Connector" products. Under the general term "D-Sign Floating," we have developed a series of new products, starting with the 0.5mm pitch connector "DY series," followed by the 0.635mm pitch connector "DW series," the 0.4mm pitch connector "DU series," and evolving into the next-generation 0.5mm pitch floating connector "DT series," which supports three-dimensional, multi-pole, and high-speed transmission. These connectors are characterized by their compact size, multi-pole capability, and high-speed transmission. 【Features】 ■ Produced in a clean area ■ Multiple connectors can be used together ■ Expanded design possibilities, enabling unprecedented designs ■ Single-point contact on the roll surface ■ Ensures a pathway for foreign objects during wiping, preventing foreign object entrapment *For more details, please refer to the PDF materials or feel free to contact us.

In public construction civil engineering sites, there are many instances where sheets are used as common temporary facilities, such as construction roads, access roads, heavy machinery work yards, material storage areas, and worker pathways. Traditionally, steel plates were common, but due to their weight, transportation and installation can be cumbersome. Hyper CLT sheets are civil engineering materials made from wooden CLT for civil engineering use. The 5×10 sheet weighs about 230 kg, and the 5×20 sheet weighs about 460 kg, making them lightweight and easy to transport, install, and remove, even with small machinery. They can be widely utilized for temporary roads, heavy machinery scaffolding, pathways within the site, and protection of material storage in public works. Since they are made of wood, they also contribute to environmental aspects such as reducing summer heat reflection, lowering noise, and fixing CO2. They can simultaneously address construction efficiency, safety measures, and environmental considerations, making them effective for innovative proposals in public works. Furthermore, they improve transportation efficiency and reduce labor in site operations as an alternative to steel plates. Hyper CLT sheets are registered technology with the Ministry of Land, Infrastructure, Transport and Tourism under NETIS "TH-250021-A." They are recommended for companies considering civil engineering, civil engineering use, and civil engineering CLT. Feel free to request materials or consult about implementation. They are temporary materials that also help improve site evaluations in public works. Please consider them.

We have released a new video on our company’s YouTube channel. The theme of this video is "The World of Amino Acid-Based Shampoos." Amino acid-based shampoos have become popular in recent years, but the lather, feel, and finish can vary greatly depending on the cleansing ingredients used. In this video, we clearly explain the changes in user experience based on the differences in cleansing ingredients by comparing two types of amino acid-based shampoos. We hope you can use this as a hint for developing original shampoos and differentiation.
