perfect flexible cable

[Winfield Hill]

It seems I'm always looking for better flexible cable
to hookup sensors, etc. The standard offerings by
Alpha and Belden are so unsatisfactory. But then I
discovered a 10-foot length of nearly perfect cable,
marked Dyden LF AWM E91337-M 2851 VW-1 23AWGx4.
It has four AWG 23 wires, in a thin, super-flexible,
but strong sheath. I have no idea where we got it.
It seems E91337 is a standard number for Dyden's
flexible cables, of all types. The Sunwa and MISUMI
distributors don't look very helpful, except perhaps
for heavy hookup wire, or CAT5 cables. Suggestions?

How about telephone handset type, "tinsel wire" ?

That's what I was considering using, but the wire is
weak, hard to solder, etc. One must also adopt the
connectors. By comparison, the Dyden wire is perfect.

The Hewlett-Packard X-Y chart recorder used a flexible printed circuit to connect the moving writing head to the fixed electronics.

The article in the Hewlett-Packard Journal on the unit went into constraints on the construction of the flexy - it had to be symmetrical, with the copper layer right in the middle, if it was going survive being flexed repeatedly.

It's all decades-old stuff - I can't even remember the X-Y-recorder number.

I've been using FFC "cable" for some time. These are
0.5mm- or 1mm-thick flat-flexible-cables available in
0.5, 1.0 or 1.25mm pitch spacing. I use a 1mm version,
and Kyocera's 6200-series connector with a clever angled
clamp. They're super useful, but there are times when
you want an honest rugged cable, with soldered ends.

Do you have any machines with moving electronic
"headpieces" nearby? (Printers/plotters/CNC etc)

They sometimes have cables loosely "encased" in
flexible trunking that looks like a hollow
caterpillar track.

Perhaps you could peer inside and see what is used.

I used this stuff just last week to test some cameras:
http://panteltje.com/pub/flexible_4_wire_cable_IMG_0235.JPG
several meters,
see no reflections at 75 Ohm termination.
No idea where I bought it, solders just fine, probably local tronix shop.
Did you measure the impedance?
I feed it 12V DC and get back video in that picture.
Could indeed be some telephone cable.
Is a very common type cable here I think.

Have you tried Unitronic FD or Unitronic FD P Plus cables from LAPP?
(https://products.lappgroup.com/online-catalogue/data-communication-systems/low-frequency-data-transmission-cables/highly-flexible-application/unitronic-fd.html,
https://products.lappgroup.com/online-catalogue/data-communication-systems/low-frequency-data-transmission-cables/highly-flexible-and-ulcsa-certified/unitronic-fd-p-plus.html)

They claim to be highly flexible, PVC or PUR sheathed and available in
multiple configurations. 4.2mm diameter with four 0.14mm2 wires.
Pretty good availability at least on this side of the Atlantic.

I use a lot of FFCs, and also prefer the 1-mm ones, mainly because
(unlike the 0.5-mm ones) they don't short adjacent pins if you put them
in a bit cockeyed.

I don't know where Lapp Group Olflex cables are made,
but they're marketed in Europe pretty widely and seem
to sell direct. Lapp Tannehill in the US.

There are some interesting cables being used for electric
bikes, from off-shore.

Alpha does offer
xtraguard, if you believe PVC can be flexible.
ecoflex, PPE or PU, if you believe PVC is a waste hazard.
19 and 41 strand 20 or 24 awg unshielded 4cond at digikey.
PPE has the thinnest OD ~0.18in /4.6mm. $4 to $7 /ft. Ouch.

What's perfect? Too flexible can be an issue under vibration.

The E91337 looks like an Underwriters' Laboratories file number I think,
so may cover all of the cables they had tested in one go. Those usually
seem to start with E.

 

Stranded sensor wire for 4-20 ma industrial sensors is awesomely flexible, supple, and tough.
