Today's automobile is already a vast network of interconnected silicon chips, controlling everything from airbags to engines operations. Alfautomazione has systems to test them.
Given the high data rates in digital applications, it is critical that a bandwidth capacity that uses a high frequency signal - typically 2.25 MHz - is available.
At these high frequencies, the system installer needs to consider such issues as return loss, insertion loss, VSWR (voltage standing wave ratio), skin effect and electromagnetic field effects.
The coax connectors traditionally used for analogue systems are not designed to take account of these issues, and if used in high-rate digital systems will put the signal integrity at risk.
To fulfil these requirements, Vitelec Electronics has introduced a range of High End 75 Ohm BNC Connectors designed to meet the specific demands of digital technology.
Including plugs for the most commonly used cables, adapters and precision crimp tooling, the range features a controlled 75 Ohm impedance for high-speed signals, captivated contacts, crimp/crimp assembly, high-performance materials, and intermatability with existing standard 50 Ohm BNCs already present within in a system.
With an insulation resistance of 5000 megohm (minimum), the range delivers a centre contact resistance of 4 milliohm (maximum) and an outer contact resistance of 3.55 milliohm (maximum), in operating temperatures of between -55 and +85 C.
Product data, providing information including detailed specification, assembly instructions and competitor cross-references, is available on request.
