7. Frequently Asked Questions
What signal types can the HSJ series integrate?
The HSJ modular platform supports differential high-speed signals, RF (up to 40 GHz), optical fiber, single-ended signals, and power contacts within a single connector housing. The user-configurable architecture allows mixing modules to meet specific application requirements.
What is the maximum data rate supported?
The standard high-speed differential modules are rated for 6.25 Gbps and are extendable to 10 Gbps. Consult the datasheet for specific configuration performance details.
How are cavities calculated in the part number?
Total cavities = (number before "G" / 4) + number after "G". For example, HSJ-12G1 yields 12/4 + 1 = 4 cavities. The default module arrangement from right to left is differential, power, then RF.
What termination styles are available?
Three termination variants are offered: crimp (no code), straight PCB mount (N3), and right-angle PCB mount (W2). The right-angle variant is available for socket (ZK) connectors.
