[Solved] Cable for 24V PWM and 3V3/5V signals: how to choose the right type

I'm building myself a software LED control on a Raspberry, via a PWM driver and darlingtons. Structurally uncomplicated. The problem arose when testing "will it work over a 30m cable" for which I am using ordinary UTP twisted pair, unshielded. Obviously, if the PWM signal is not 100% filled, the adjacent twisted pair wires are peed on and the LEDs glow slightly (which was to be expected). As there is not a lot of experience in cable selection, maybe you can advise something. . Basically I need a cable with which I could transmit 24V PWM and some two 3V3 or 5V signals, maybe 1Wire. I know there are twisted pair shielded cables but I have not been able to find this in less than a kilometre. The idea is to run one multi-conductor cable rather than several separate ones. Does anyone recommend any particular cable for such applications not for millions?

This cable I'm using is just CAT5e - in my humble opinion there should be a cable with shielded pairs for this. And that's what I can't find...

Search under U/FTP (each pair separately shielded) or F/FTP (each pair separately shielded in addition the whole thing is also shielded) they are sold by the metre.

no, nothing like expert advice - I found right away
Thanks a lot

The use of FTP cable, i.e. with shielded (foiled) pairs of wires.
