For cable, see page 46 of the online Digikey catalog
searching for MB37R-5-ND will get you there
For plugs and receptacles you can search under
HMM37H-ND for the plug
HFM37H-ND for the receptacle
and land on page 48
There are 25 pin cables, plugs and receptacles as well.
There is some shielded cable on the bottom right hand
side of page 46 as well.
As noted earlier, the current limit for the 28 gauge wire
used in this ribbon cable is listed at .228 amps and the
solenoid outputs can exceed this.
There are always the screw machine db-xx connectors
that one can resort to. We get ours from
www.steinair.com.
These can handle up to 20 gauge wire and will be very reliable,
but it will be tedious to be crimping and inserting them one by one.
