Hirose's latest product is a compression-mounted 2.4mm coaxial connector suitable for applications such as laboratory equipment, test equipment, feature boards, and high-speed backplanes for data / computing and network analyzers. The H2.4 series complies with the MIL-STD348B standard and supports transmission speeds up to 50GHz and 25Gbps.
The high-bandwidth H2.4 series coaxial connector adopts a pile-free design and is fixed on the PCB by screws, which simplifies the assembly process and has electrical and mechanical advantages over the soldered version. For traditional solder through-hole type models, signal reflection may be caused by the stub protruding from the board, but for H2.4 compression-mounted connectors, the center contact should be installed flush with the PCB. This eliminates stubs and significantly reduces signal reflections.
The H2.4 series can also be used with PCBs of various thicknesses (min. 1.6mm) to optimize design flexibility. In addition, the connector is reusable, and boards can be attached and detached for multiple uses, saving time and money.
Solder terminals inherently introduce the possibility of human error. The screw mounting design eliminates this human error variable and ensures a high-reliability connector with excellent high-frequency performance and consistent assembly quality. "Rick van Weezel, vice president of sales and marketing at Hirose Electric USA." Through-hole mounting types are also limited to one PCB thickness, but headless screw mounting types can achieve various PCB thicknesses with one connector type. ”
H2.4 series plugs are made of 0.085 inch semi-flexible cables, each end has a termination plug, and the socket has a gold-plated ground ring to stabilize the ground on the PCB.
The center contact resistance of the connector is up to 4mohm, and the external maximum The contact resistance is 2mohm. The H2.4 series connector series is rated for 500 mating cycles and has a characteristic impedance of 50ohm.
