Proper way to joint two AWG 28 wire together ?, one is solid and one is flexible, how to joint that wire properly and massively and easely ?, about 200 connections need to be jointed

 

How are the conductors arranged? Are the individual or in a multi conductor cable? Are the exposed to the outdoors? Are they in a cabinet?

 

What I might do is to put RJ45 connectors on both ends and use a coupler. Make sure you get the RJ45 connectors for both solid and stranded or the one used for both.

A 110 punch down block https://en.wikipedia.org/wiki/110_block might work, but I don't know if it;s OK for stranded wires.

I'd say solder and adhesive heat shrink but 200 connections, no.

 

Twist-solder-insulate and you are done. The insulation should be heat shrink tubing so it also offers some strain relief to "soften" then bend at the end of the solder.

 

Western Union splice, solder, heat shrink tubing.

Individually, that cable came from cat 5e 8 core wire, but connected individually, previously we only use western union and tape, but that joint technique isn't really good

Well, it would help to know how they are being used. Do they have to stand up to the weather? Are they in a cabinet? Are they bundled in any way?

Yes... in one side I use RJ45 and cat5e, but cat5e is connected to 28awg wire individually, I was think to make controller redesign with RJ45 port inside instead individually 28 awg female ports, but now that think isn't possible (because deadline time and cost)

Is in the cabinet, and only small cabinet, about 30 cm x 40 cm x 15 cm (L x W x H)

Also maintenance is very hard

 

Well, I would be inclined to use terminal blocks, probably on a DIN rail, but the space may be two restricted.

Telephone "B" connectors would probably be my second choice.

because...?

Controller I/O ports is AWG 28 female ports, I think to redesign them to use RJ45 female, but I can't do that now

 

There is a proper tool for crimping: https://www.amazon.com/Jonard-JIC-891-Connector-Crimping-Cutter/dp/B006962DPO/

Do you have reference for PCB printing ? with industrial grade but not very expensive ?

 

It is good idea to connect 28 awg flexible wire to RJ45 connector ?

I don't but many people here have a lot of experience with fabricators. I have decided in JLCPCB but I haven't been able to test them yet.

Modular connectors have versions for solid and stranded cable. Get the right one.

Ok... If I can use RJ45 with flexible cable I don't really need cable joint anymore, but previously I was try that and result isn't good...
