This is a product line of 0.4mm pitch Floating Connector. They are low profile, space-saving, and have high heat resistance specifications that are compatible with in-vehicle equipment, absorbing misalignment after Mating, and can also handle heat generated around the engine in in-vehicle equipment and due to the increasing functionality of devices.
low profile, space-saving design yet supports high-speed transmission. Impedance matching: Differential 100Ω.
・10126B/11007S 12.0Gbps *1 Supports high-speed transmission
・10126B/10126S 8.0Gbps *1 Supports high-speed transmission
*1 Representative reference value defined by our company.

High heat resistance is required for connector products due to the rise in heat generated by engines in automotive equipment and the increasing sophistication of devices. Our high heat-resistant products, realized through the full use of our materials and design technology, can be used safely in harsh high-temperature environments up to 125°C.

The 10126B/S series Floating structure Board to Board Connectors Floating move 0.4mm in the X/Y directions to accommodate misalignment between boards.
This makes it easier to adjust the alignment when connecting multiple connectors and reduces stress on the soldered parts.

Compared to pull-out terminals, the contact surface is less rough, allowing for smooth insertion and removal.
Reduces damage (chip away from plating) to Mating terminal surface (improved insertion/removal durability compared to pull-out terminals).
The appropriate guide structure improves Mating workability.

As global environmental issues become more serious, the global trend toward decarbonization is driving a shift to electric vehicles (EVs). IRISO Electronics is strengthening its development of connectors suitable for EV ECU devices and is working to realize a carbon-neutral society.
We have developed a Board to Board Connector connector suitable for in-vehicle environments that contributes to the miniaturization and weight reduction of devices.

It has "high-speed transmission characteristics" (PCI Express Gen3.0 Spec) that support high-speed communication.
