[dsg-hdice] Modify/reuse 2 Molex cables

[Xiangdong Wei]

Correct, the center conductor won't fit. So we need to search for a new one. Would you please help?

When searching the connector last week, I only considered the outer jack hole (the Molex cable without outer plastic tubing was 3.51mm---see the attached picture).

Thanks,

Xiangdong

Mindy already placed an order for these connectors and it's been signed. However, I'm not entirely sure it will work as some of the dimensions seem to small as it is meant for RG-402.

The center conductor hole size is only 1 mm (Molex is 1.15 mm vs RG-402 at 0.91 mm)
The outer jacket hole is 3.7 mm (Molex is 4 mm vs RG-402 at 3.58 mm)

Since the dimensions for the Molex Temp-Flex are big in some areas and small in others the adapters we got machined in the past are for installing the Molex cable inside of a connector meant for 0.25" semi rigid cable.

Since the ones you found were only $3 each I don't think it's any big loss to try and see if they work, but should I go ahead and order some female SMAs I know the cable will fit in? They're more like ~$11 each.

The SMA connector for RG402 or RG58 will work (You may need to put a piece of very thin copper sheet to fill a tiny gap). I checked the Newark website and found this one on sale (please see the attachment). Please take a look. They have 500 in stock. You can get 5 or 10 of them.
