KEL Product Lineup

For several years, we have been developing connectors compatible with crimped cables at KER. We have now developed a new 5.08mm pitch high-current connector, the "FTC Series." This connector is primarily designed for use in high-current applications, with the intention of being adopted in factories and power-related distribution panels. Until now, we have focused on compact and thin designs, but we have successfully completed a high-current connector utilizing that expertise. <Features> - By crimping two cables, we can reduce the number of contacts in the connector, achieving a smaller size! - Power transfer between connectors is done directly without using a circuit board or terminal block! - Compatible cables include four types: AWG#14, 16, 18, and 20.

With the trend towards thinner and more portable laptops, the batteries used in them are also required to be thinner and lighter. The form of these batteries is transitioning from lithium-ion batteries to lithium polymer batteries, which offer greater freedom of shape and higher power capacity per unit area. The GF series achieves a significant reduction in height, with a mounting height of 3.4mm (on the laptop side) and 2.6mm (on the battery pack side), compared to conventional products. Naturally, the adoption of lithium polymer batteries also requires connectors to be thinner than before, making this series an optimal choice. Additionally, it features a high reliability with a mating stroke of 1.6mm.

This is a connector for battery packs of small devices such as laptops and handheld terminals.

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.

The "drawer connector" is a type of connector used in areas that are often hidden, such as deep within a housing, where mating occurs. It provides stable contact force through two-point contact, and the contacts are gold-plated, resulting in low insertion and extraction force as well as excellent durability against repeated insertions and extractions. Additionally, the contacts are plate-shaped, ensuring a safe structure that does not put direct stress on the pins even when mated at an angle. 【Features】 ■ High contact reliability ■ No concern about pin buckling ■ Easy adjustment of mating position ■ Absorbs shock even after mating *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.*

"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.*

KEL Corporation's "Ultra-Fine Coaxial Cable Connectors" are suitable for ultra-fine coaxial cables that are necessary for miniaturizing equipment and supporting high-resolution images.
