32 AWG Wire Connection

[bsmith736464]

Hi - I apologize in advance for the beginner question but I have a haptic motor with 32 gauge wire on the end. Any advice on how to connect that to a breadboard? Can I solder one end to a 24 gauge wire or are there any connectors for a small wire?

Thanks.

32 gauge wire

Solid or stranded? Makes a big difference. If solid, you need a fixed location to put those wires and then you can solder flexible wires at that point.

If those 32 gauge wires are flexible, you need to tin those wires and the 24 gauge wires and then you can solder them together. And put heat shrink tubing over the splice and shrink it to hold and protect the wires.

You can make durable jumper cables for your solderless breadboard by using heat shrink instead of a Dupont housing. The heat shrink acts as a strain relief. Clear heat shrink lets you see the condition of the M/F connector. [A.jpg] [B.jpg] [C.jpg]

A wire splice is a reasonable solution to connect a large gauge wire to DuPont pin connectors. If you need a higher current connection, use two DuPont pins. The reverse is also true; a 30 AWG sensor wire can be spliced to a more reasonable 22/24 AWG wire. [A.jpg] Works the other way too, smaller to larger: [image]

PCB Eyelets Used as Wire Ferrules PCB eyelets crimped on stranded wires keeps those strands under control. This process makes wire connections easier and less likely to result in fabrication problems.

28 AWG DIY ferrules for screw terminals In another post, a user asked how to terminate 28 AWG wire in a screw type terminal strip. @6v6gt suggested to use a Dupont crimp connector to act as homemade ferrule. Below shows how this process can be accomplished. Add heat shrink to act as a strain relief. The colour of this heat shrink can identify the terminal number to use: Yellow would be terminal #4 Brown and Yellow would be #14, etc. [A] [B] [C] [D] [E] [F]

I'd be worried about the 32 AWG wire breaking so hopefully there's a way to lock it down (tie-wrap it or glue it to to the motor or something) so only the heavier gauge wires get flexed or pulled-on.

Thank. The wire is solid. Hopefully that helps.
