Noritsu coaxial cable type

[alexvigor]

Hi! I need to replace coaxial cable in qss32 (AOM driver to Laser control pcb). Is it possible to make my own cable - I have bnc sockets, but what type of cable can i use? Visually it looks like RG178 or RG316. Anyone did this? Is it even possible?

Thx!

Yes, you can make it. Use BNC connectors and any 50 ohm coaxial cable.

One side BNC connector and other SMB connector. 
AOM driver locations are different. Cable length depends on printer model and color. You can measure cable length on printer.

On Noritsu AOM crystal -  SMB type, male contact,  right angle,  50 ohm, silver color connector for pcb.
On cable -  SMB type plug, female contact, right angle,  50 ohm, connector for cable.
