Stepper motor 6 pin locking female plug

Guys,

My google skills are failing me today. And not a wiff on ebay except supplied with the motors.
Does anyone know the name, spec or part numbers for the 6 pin female plugs on my Nema17 stepper motors.
I want to bit of rewiring and could do with getting 5 of these with crimps to make a new wiring loom for my printer.





Thanks

Gordon

Found out what they are now.
JST 6 way 2mm

Available from places like farnell.

Gordon

Oh no its not.
They arrived in the post and are too large. So not the 2mm version.

Gordon

Look out, JST do various ranges which look quite similar. If you PM me tomorrow during the day as a reminder I'll look them up on our database and might be able to help.

I think ive foound them theyre the 1.5mm version not the 2mm.
Ive got some on the way to try.

Tried ordering them from farnell as theyre not that expensive but couldnt think of anything else i wanted at the time to pad the order out to the £20 minimum.
So ended up ordering them through ebay from the far east as it worked out cheaper.
Im hoping my crimp tool fits the connectors. It fits the tiny kk pin header crimps. So heres hoping i dont have to geg yet another crimp tool.

Gordon

Hmm, I think they are JST PHR-6 which is indeed a 2mm pitch connector. What did you order exactly and where from?

Of course we're assuming your motors use the same connector as mine!

I just measured the pin spacing on 2 different types of NEMA 17 stepper motor, and both are definitely 2mm pitch.

I am surprised there is nobody selling stepper motor cables with connector on one end on ebay.

I came across one company in the US but they were pretty expensive.
And farnell sell pre crimped wires to go in the housing but they were very expensive.

The 2mm ones were definetly too big for my nema 17 steppers.

Any chance you could post the *exact* spec of these too-big ones?
If you bought from somewhere like Farnell then their product code or whatever
Also the exact markings on the packet.

Either your motors are different than mine or you bought the wrong thing or the supplier shipped the wrong thing.

I've looked up the details at work and I've inspected a raw JST-PH6 socket (that's the part which you would be plugging in to, the bit on the motor housing) and I'm pretty convinced mine really is JST-PH6. Unfortunately we don't have any PH plugs in the factory at the moment so I can't do the ultimate test and actually plug one in.

Once you do manage to sort out which series it is check the crimp spec carefully before buying ready made wires or crimps, the JST range is a nightmare of very similar looking parts which nearly interwork but don't. I'm happy to talk you through that once you can identify the range.
Oh, and your KK tooling won't work properly for JST crimps and you won't wont to cough for a JST crimp tool once you see the price.

I just orded these [www.aliexpress.com]

That's what I'd expect to work. Cheap too, if you want 50 off that is.

Csambrook,

Heres the 2 together.
The 2mm i just ordered is too big seen here next to the one on my printer.


Heres my original on a scale.

And on the vernier jaws

Sorry that ones a bit blurry but it does seem to be 1.5mm between centres on the crimps.

And the new too big one.


These were the first ones that are too big.
[www.ebay.co.uk]

These are the next lot im waiting for.

Seems wasteful to to buy male and female but either ill use them or ill pass them on at our makerspace. so they will get used.

Yes, those crimp tools are astronomical.

Gordon.

Well there's your answer.

The ones you bought weren't 2mm but 2.5mm pitch. They are JST-XH series, sadly JST make loads which look the same in pictures but are incompatible.
Sadly I don't think your new ones will fit either as they are JST-ZH series which are different again.

Which country are you in? (Actually, where's it easiest for you to buy from?). I'll look up something suitable and send you a link to what I think will work for you, although the Aliexpress one given earlier looks good.

Thanks. Id appreciate that.

I ordeRed the first lot as i read elsewhere the rc crowd used the 2mm ones for charging/balancing battery packs.
Made an asumption these were 2mm. now i look at the add theres no mention of 2mm.
Doh.

Im in the UK.
Farnell UK wanted £20 minimum order.
RS UK didnt have the crimps in stock. But did have the housings. But that was based on me looking at the zh series.
Gave up on Maplin on something this specialist.

Do you think i still need 2mm rather than 1.5mm?

Thanks

Gordon

Right, I think we've settled on it being JST-PH6. I borrowed a plug to check against my printer but it's been in full use this evening so I haven't had chance to take it apart to check - sorry.

You have some choices:
RS, Farnell and DigiKey all stock the bits but it will cost you.

Alternatively there's ebay at about £4 plus a wait:
[www.ebay.co.uk]

Or Technorobots:
[www.technobotsonline.com] for the housing £0.06
[www.technobotsonline.com] for the pre-wired crimps £1.48
Plus £3 shipping
The 6 way housing is just a bare housing. The 5 way assembly is a plug, socket and wires so you'll need to remove the crimps from the housing and discard the plug and 5 way socket - it's easy to do as the plastic of the plug can be bent up without damaging the crimps at all. That will give you 5 wires with crimps already on them, you only need 4 per housing for a standard stepper arrangement so you'll have a spare. For your original desire for 5 assemblies that gets you:
5 * £1.54 + £3 shipping = under £11 all up.

Hope that helps,
Calvin

Thanks very much.
Thats given me some options.
My ramps board has just toasted the power connector for the heated bed supply and is now going nuts ovefheating the nozzle.
[forums.reprap.org]
So once ive troubleshootdd that ill go through those links and get some ordered.

Looks like ill have to break out the spare and then have a play at fixing it.

I appreciate thd time you took to look that lot up.
Thanks.
Gordon

Gone for the technorobots order.
Ill let you know when i get them and what theyre like.
Thanks again

Gordon

Yep, they are the right ones.
I can swap the already crimped wires over to the empty housings to give me the 4 wires.
The tails are only a few inches long so ill have to solder longer wiring to them.

Thanks again.

Gordon

Thanks for confirming that! Now I know what to order.

Im not the greatest at documentation but little bits of info like this is usefull to share.
And the forum is searcheable so it should be findable by others.

And for future reference E3D do ready made ones at 1200 mm long for £1.50 each
