quick question on wire type

Is anyone aware of breadboard hookup wire that is pliable, flexible? Less stiff than usual hookup wire? I have some sensors I am prototyping that are several feet away from base-board and working with the usual wire is cumbersome.

I'd use a jack or some other "interface" between the board and the flexible (stranded) cable to the sensor.

I either use a dual screw terminals that are .2" spaced and can be slotted together for ganged use or a IDC header and use ribbon cable.
Or even just a few strands of ribbon soldered to the Vero strip board (0.1" spacing).
Max.

I'd use ribbon cable with a male header pin crimped on to the end that will be inserted in the breadboard.
From Jameco.com:

This is something I have no problems buying from AliExpress. Much cheaper and they work fine. A ratcheting crimp tool is under $20 (AliExpress).

Side note; In my own experience these types of wires work OK for DC and low frequency stuff, but for I2C or SPI or anything else that has a relatively higher frequency clock, the connections aren't always reliable enough and communication can be flaky, leading to wasted time and frustration trying to debug the actual problem.

I was looking at these - problem is my sensor has a very small profile. Its on a 4 x 4 or 2 x 4 mini-breadboard. I'm afraid the black piece that is the jumper in your recommendation will create a reflection, shadow, etc. If I could bend the protruding wire of the piece at a right angle I may be able to both connect the piece and make sure it doesn't obstruct the sensor (IR led). Do you think the protruding wire will sustain bending?

Have to find a solution that will fit breadboard to breadboard with a stranded cable with a breadboard compatible termination.

I have to find how to tailor the other end to fit in the mini-breadboard (2x4 or 4 x 4) several feet away. If the terminating piece is too big or overshadowing it could interfere with sensor activity. Ideally just a right-angle wire would be the best for the mini's, but the screw terminals are good to go.

Ok - I've got a regular breadboard that is suitable for this. : )
How do I apply your solution to my "satellite/remote" breadboards (2 x 4 or 4 x 4) from the base breadboard? I'm looking at what you are recommending and it looks very cool, but not clear on how it comes together.

This is an example:

The white wires go from the breadboard to a SBC. I can't remember if the rainbow jumpers were premade or custom. In either case, your requirements would require a custom length, so you need to make your own.

The white jumpers are #22 stranded, which is probably not flexible enough for your requirements. The rainbow jumpers are standard #28 (7/#36) ribbon cable.

The white jumpers use some female connector that I bought surplus. I don't have the shrouds, so I use heatshrink to keep the connector from spreading when mated to a male header. I use long tail male headers on the breadboard for connections. The rainbow jumpers are either male-male, male-female, or female-female as needed.

If you are speaking bout my solution, you solder the short part of the header to the wire and plug it where ever you want. It will fit exactly like a normla plug in wire in side of the board. In fact on those chips on the left of the picture you have the same headers. The short is soldered to the chip. the long is plugged in.

I was responding to the OP.

Hey Max why do you recommend this?
Some people feel that solderless breadboards aren't reliable.

I'm not one of them. Been using them for 40+ years and the only problem I've had is ends of wires breaking off because they were nicked while being stripped (my fault). Breaks were found using standard troubleshooting procedures.

Prototype for a 4x4x4 LED cube. All of the jumpers on the right half were custom made.
