Hi All
I'm having a dilemna at the moment, I have designned a battery balancing circuit and need connector for this that are rated at 10A max per contact perivously I used a SAMTEC IPBT connector which met my requirement the only problem was the height with the connector and the mating half had a height that was a lot greater than the height of the mechanical enclosure this PCB is going into. Can anyone please help me with this. The connector needs to be specifically surface mount, and needs to come to height of 20mm with mating half included (goes to cables). I was thinking even right angled connectors would be suitable.

Kind Regards

Do you mean "PCB mount" or do you have a strong affection for surface mount?

I would recommend these for high current application. The top screws can handle 12gauge wires. 15A and 20A styles are available.

Yeah unforuntaley surface mount as I am using a IMS PCB

I do appreciate the suggestion though if you had any other ideas they are warmly welcome

Please provide more specifications..
Board to board connectors?
Wire to board connector?
you mentioned cables? What AWG?
number of terminals?
polarized?
Locking features?
mechanical securement needed?
blind mate?
number of cycles?
,etc...

the more info you post the better the answer will be..

1) it's a Wire to board connector
2) 20 AWG
3) 4 terminals
4) Doesn't need to be polarized
5) Not really bothered about Locking features
6) Same as above mechanical securement isn't a big issuse.

The main properites are 4 way, 10A current per contact and surface mountable because it's on an IMS PCB and finally height of connector and mate must be 20mm or less

So wire to board..
Is that ribbon cable?
or discrete IDC? Crimp? Screw down terminals (as shown in post#2)? barrier strips/ring terminals?
I'll assume you need the wires to exit parallel to the PCB surface right?

Maybe something like TE MTA-156 series? I think thats just above the 20mm though..

Have you gone through the searches at digikey? mouser? newark?

I have tried digikey, mouser and newark (farnell), they can exist parallel or perpendicular as long as the height, I think height the absoulate max was 24 mm

I guess the MTA156 does not come in a surface mount version..
I use tons of the MTA100 and they do so I just assumed..

Any reason you can't use through hole for those connectors?
Mixed assembly (SMT+TH) is done all the time now..
I personally would be worried about 10+Amps through a surface mount connector only without some sort of mechanical attachment also..

Because this is for an IMS board, I have used SAMTEC IPBT connectors before but it caused the height problem in the past

Thanks all, I decided to change my design and reduce the current down to 5A the following is the connector I ended up using: Samtecs: IPL1-104-02-F-SH-K thanks all for the assistance
