Cables for connecting sensors to Pi

Sat Oct 27, 2018 3:43 pm

The regular 12 in jumper wires are too short for my industrial application. What other cables can be used to connect sensor to pi. Need atleast 2 meter long cable

For cables that long you will probably have to make your own..

It depends rs on how you intend to make them.

If you are just going to crimp new terminals on the ends of cables of the correct length to make your own Dupont cables then the supplier of the crimper and terminals will probably be able to supply instructions on using the crimper.

Not much else to it.

If you intend to use some there type of cable then you need to specify what you intend to use .

i took the F2F wires and cut them 4 inches from connector. Then soldered and hot glued to another long wire....Not an elegant solution, but works !!

If this is an industrial application, you go out to a third party supplier, tell them what you want and have them send you a quote for making that specific cable.
Cutting cables and splicing another one in is not a professional solution.

(Or at the very least you buy the correct crimping tool and crimps to make your own cable from a single length of wire)

I realise you said "2m" but depending on your sensors, your application, the frequency of change of the signal and the noise level in the intended environment, you may find that simply extending a cable that works at 20cm will not work so well at ten times the length.

You really need to investigate (or take professional advice) regarding the signal transfer issues in your professional application. You may need special signal sending, receiving, modulation and/or shielding on this "2m cable" - assuming you want it to work reliably.

If you're lucky - you may not! :)

If your sensor works at 2m, I would at least replace the hot glue with heat shrink sleeving for a more professional look
