Bob, etal



I have an ElecIntl MVP-50 engine monitor.  The various probes connect to

three Dsub 37 connectors on the box (via a user created harness).

To get the engine prob wires through the firewall I have a few options:



1. Drill a hole, and use a flange and a piece of fire sleeve and a couple

wire ties (quick and cheep)

2. Get a few large Amp/mil-spec bayonet style multi-pin round plugs

(expensive and heavy)

3. Fabricate/find three Dsub 37 bulkhead connectors and use the provided

cable components and a standard Dsub 37-to-37 straight thru cable.  Thus:

connect the probes to the provided Dsum37 connectors, connect those to the

dsub37 bulkhead connectors, connect the back side of those to the

dsub37-to-37 straight through cables, connect the other end of the cables to

the engine monitor box (dsub 37).  i.e. Seems it would be "clean" to just

use the same style connectors throughout.



Have you ever see a thing such as Dsub37 bulkhead socket?


	


   Not one that's fire-rated . . .

normal one with bigger flanges.  Have you ever seen one that had male pins

on one side and female plugs on the other (straight through)?  Ideally it

would be > 1/2" depth in the center to get through the firewall.  Or perhaps

a similar gender changer and then I'd find/make a mating cable?


	


   What's your design goal? If ease of installation an maintenance

   supercedes concerns for fire wall integrity, then panel mounted

   d-subs to take wires through the fire wall are a consideration.



   If it were my airplane, I'd take the bundle through fittings

   not unlike these . .

   These are techniques used on some present production TC aircraft.

   There are no doubt equivalent and perhaps more attractive

   techniques. I've not had time to research them.

I've either have, or have had, some D-subs that had a ceramic material 
	


in the center that held the pins.  I have no technical data at all about 

what the filler material was, but it looked more robust than the typical 

plastic center sections.  I don't know where I got the old connectors 

from, and a quick Google search didn't turn up anything useful.  If I 

still have them in my toolbox, I'll post a picture before and after I 

put a torch to them.

Is there any problem with breaking a thermocouple wire at the 

firewall with a bulkhead connector?
