New compression-mount 2.4mm coaxial connector
Connectors, Switches & EMECH
Latest from Hirose is a compression-mounted 2.4mm coaxial connector aimed at
applications such as lab equipment, test equipment, characterization boards,
and high-speed backplanes for data / computing and network analyzers. The
H2.4 Series meets the MIL-STD348B standard, and supports up to 50GHz with a
transmission speed of 25Gbps.
Featuring a stub-less design with screw-mounting to the PCB, the
high-bandwidth H2.4 Series coaxial connector simplifies the assembly process
and provides several electrical and mechanical advantages over soldered
versions. With traditional soldered through-hole type models, signal
reflection may be caused by the stub protruding through the board, but the
with H2.4 compression-mounted connector, the centre contact is mounted flush
with the PCB. This eliminates the stub, and signal reflection is
The H2.4 Series also optimizes design flexibility as it can be used with PCB
boards of various thicknesses (1.6mm minimum). In addition, the connector is
reusable and can be attached and removed to boards for multiple uses, saving
time and costs, says the company.
"Solder terminations inherently introduce the potential for human error. A
screw mount design eliminates this human error variable and ensures a high
reliability connector with excellent high- frequency performance and
consistent assembly quality," said Rick van Weezel, vice-president of sales
and marketing, Hirose Electric USA. "Through-hole mount types are also
limited to one PCB thickness, but a stubless screw mount type allows for
various PCB thickness with one connector type."
The H2.4 Series plug is manufactured with a 0.085 inch semi-flexible cable
with terminated plugs on each end, and the receptacle features a gold-plated
ground ring for stabilizing grounding on the PCB.
The connector has a contact resistance of 4mohm max in the centre and 2mohm
max in the outer section. This H2.4 Series connector series is rated for 500
mating cycles with a characteristic impedance of 50ohm.
