• Board to Cable Connector

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.

• Board to Cable Connector

Stack height 25mm! We have developed additional variations of the high stack type.

We have developed the 'DT Series' floating connector with a 0.5mm pitch that supports high-speed transmission, featuring a stack height of 25mm. It ensures a high floating amount of ±1.0mm in the XY direction, enabling high-speed serial transmission equivalent to 8Gbps. We offer seven types of pin counts ranging from 30 to 140 pins, and by combining them with the existing receptacle side of this series, it can also accommodate a stack height of 15mm. 【Features】 - 0.5mm pitch floating connector compatible with high-speed transmission - Transmission characteristics support high-speed serial transmission equivalent to 8Gbps - High floating amount of ±1.0mm in the XY direction - High-reliability design with an effective mating length of 1.5mm - Compatible with a stack height of 25mm - Seven types of pin counts: 30, 40, 60, 80, 100, 120, and 140 pins *For more details, please refer to the PDF document or feel free to contact us.

0.5mm pitch floating connector "DY Series"

The "DY series" features a 0.5mm pitch and a narrow pitch while ensuring a floating amount of ±0.5mm in the XY direction. Its compact size and large displacement contribute to the miniaturization of equipment. The effective mating length is secured at 1.25mm, making it a user-friendly product that boasts stable contact. Additionally, it offers the option to choose whether or not to include positioning bosses, as well as features that ensure a suction surface during automatic mounting. The floating side connector is composed of two parts: the contact section (movable part) and the soldering section (fixed side), which are connected by contacts. When the contact section moves, a load is applied to the soldering section; however, by attaching fixing brackets to both ends of the insulator, the structure is designed to reduce this load. The contact shape is compatible with SMT, and the plating is lead-free. *For more details, please refer to the catalog or feel free to contact us.*

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.

At construction sites, temporary parking lots may be established for workers and construction-related vehicles. On unpaved ground, mud and ruts can easily occur due to rain, which may hinder vehicle access. Hyper CLT mats are civil engineering materials that utilize wood CLT. By laying them in temporary parking lots, a suitable environment for vehicle passage and parking can be created while protecting the ground. They can be laid only in the necessary areas, and after the construction is completed, they can be removed and repurposed for temporary roads or access routes. The 5×10 panels weigh approximately 230 kg, and the 5×20 panels weigh about 460 kg, making them lightweight and easy to install and remove even with small machinery, allowing for changes in parking space. Additionally, they offer benefits unique to wood, such as glare reduction, noise reduction, and CO2 fixation. They are registered as a technology with the Ministry of Land, Infrastructure, Transport and Tourism under NETIS as "TH-250021-A," and can be utilized for the development of temporary parking lots and innovative public works.

Metal cracks are one of the concerns in equipment maintenance operations. Conventional welding repair methods can change the base material around the crack due to heat, leading to residual stress and deformation, which always carries the risk of "crack recurrence" and "secondary damage." Hinode Water Supply Equipment Co., Ltd.'s "Mechanical Stitching Method" is a new technique that allows for the repair of metal cracks without applying heat. By using special bolts and reinforcement plates, the crack is physically removed without affecting the base material at all. Repairs can be made even in environments where open flames cannot be used. Since no heat is applied, the disassembly of equipment is minimized. For more details, please contact us or download the catalog.
