Where to find the motor side connectors used on Nema17s?

elliott.griffiths

I need some for a project, but I can only find the female pin side housing and crimps (JST-PH6 I believe). Any advice would be appreciated.

I have not seen male connectors for 2.0mm JST PH, only PCB headers which you could solder wires to but its not optimal.

I have found cable assemblies on amazon.

wrong size. thats 2.54mm JST XH, not 2.0mm JST PH

Maybe OP could ask this seller if he could supply 6-pin version, some are quite happy to help, if they understand the question.. https://www.ebay.com/itm/100-SET-JST-PH-2-0mm-2-Pin-Li-PO-Male-Housing-Connector-with-Crimp-Pin-terminal-/113549526440
Beyond that I only see pre-crimped:

(hadn't found similar before)

Search AliExpress for PH2.0 and I believe that you will find what you are looking for. The Nema17 use the 6 pins connectors.

@bearer You are correct. Thank you for pointing that out.

Male crimp connectors? I've searched for 3 and 4 pins before without luck, only the preassembled cable like i linked to. I was shocked to find 2pin male on eBay. If you stumble onto a link please share, I'm still hunting for 3 and 4 pins for other projects:)

Not crimps but PCB TH (can also be soldered with a shrink tube), straight and right angle. E.g.

Edit: looking at JST's website for the PH series, the male side doesn't seem to come with a crimp version, just TH PCB (their website is built such that it's difficult to share links).

There are non-JST branded (or rather unbranded maybe), but I've never seen them offered uncrimped with the exception of the 2 pin on eBay a few posts up. I send the guy a message asking for 3 and 4 pins, but don't expect an answer until after new year over there.

edit: he actually offered 2,3, and 4 pin so I ordered some. Could still be worth asking for 6 pin

@elliott-griffiths mahbe this can work? https://www.aliexpress.com/item/32879665640.html

(unrelated that guy is offering 3.96 VH connectors as well)

Hi all,

Thank you very much for all your responses! This is why this community is awesome

Decided to go with @bearer latest suggestion, thanks! Will make a circuit board to adapt I guess, many thanks!

why do you need a board? whats the use case?

@bearer Essentially we have a piece of equipment that doesn't support reversing the extruder at the moment (it's actually made for something else). So I want to reverse the direction of the NEMA - but there are a couple of different extruders we use, some geared, some not - so an adaptor to reverse the motor would be ideal for quick switching.

@elliott-griffiths so you'll do a relay hooked to the direction pin or something? interesting!
(but can you not use a through hole or surface mount 6-pin PH connector if you need a board anyway?)

What's wrong with M569 ? Are you looking to use exactly the same config.g file with different extruders?
