MOTM

Hi Paul, List,

does anyone happen to know the Farnell order code for the power
cables used on the MOTM modules? (Between the MTA connectors)
I am having trouble identifying it and my eyesight is rapidly decaying
looking at the small print on the catalogue pages.

TIA

The cable is custom made. It uses AMP MTA-156 crimp connectors and 18ga
wire. I sell the
cables in the catalog.

hello,

i have them here, i had a minor problem not being able to get the correct
wire guage, but:

0.156" four way housing - 588-910 (24awg)
0.156" four way header - 589-068 (24 awg / friction lock straight)
0.156" four way dust cover - 589-019
0.1" four way dust cover - 588-350
0.1" four way header - 588-593 (24awg / friction lock straight) - the bit on
the board
0.1" four way housing - 588-179 (24awg) - the bit on the cable

the 0.1" sizes are used on the earlier Oakley modules, sorry i don't have
any sizes. important - please check when ordering that i've not dropped a
digit here, i'd hate to have you ordering something bizarre
i'd also highly recommend getting some kind of impact tool to assemble
these, a tenner spent is well worth keeping all your fingers intact...

cheers

Hi Paul,

I already have the correct MTA connectors, its the correct cable I was after

many thanks for your trouble anyhow

I use the Molex 0.156" connectors or other Farnell equivalent. These are
compatible with the MTA stuff, but they are crimp connections as opposed
to IDC. IDC can be a fiddle without the right tool. You can also solder
them too, and this is what I do. If you solder into crimp connectors,
you can use pretty much any wire size you need. It takes a bit of
practice, but it gives a very good finish. UK 13A mains cable provides
nice and cheap wire for this very purpose if you strip the outer casing
off.

My main reason for doing this is that my system has only one end of the
power cable wired to plugs. The other end is soldered to a four way bus
bar that runs along the length of the cabinet. ( Its a bit sad to chop
off one end of the MOTM cable... ) I use 22A twin and earth cable and
strip the 2 copper wires from this to form the bus bars. Its not star
earthing of course, but the bar thickness keeps the resistance to a
minimum, and hasn't appeared to give any problems yet. Each 2U or 3U
wide space has its own power connector dangling from the bars. The bars
are held into place by small bits of wood screwed to back panel. The
wood has four little holes through it to guide the wire.

But what I would like to see is a long 8U wide PCB with 12 MTA headers
on it all star connected to an input one. This could be used instead of
the bus bar system for all those wooden cabinet people. Paul?

You could always get Paul's super-long cable and cut it in half to get two
single-ended power cables. Just a thought.

I thought there *was* an enlarged power distribution board in the works...?
The current one has 11 connectors after power supply connection, which is
far too little for us cabinet guys. You can gang multiple boards, but you
lose one or two connectors on each every time you do this.

You really shouldn't use the MTA connectors to gang multiple boards, 
try running a second set of wires from the power supply to the faston 
connectors on the power distribution board. This only gives you 24 
connections, but it will keep you from running too much current through 
the first board and/or wires. -Nate

There is a super-duper long one in the works. I'm ordering connectors for it
today.

Paul S.

how many connectors? approx what price? -Nate

Actually, to strictly maintain the star system, the best thing to do 
would be to attach the PS to a terminal strip, then run each power 
dist board directly back to the terminal strip instead of plugging 
them into each other. Then you don't lose 1 plug per board.
