military connector substitution

Hello, all,
I just got a really nice servo motor on eBay, and it has
military bayonet connectors on it, PT02E-14-18P and
PT02E-14-5P. I dug through my junk box and couldn't find a mate
to these. (I did have some 14-19, but no 14-18.)
Does anyone know if there is a plastic or low-cost version of
these connectors? I looked up the mating part in Digi-Key and
Mouser, and they run about $30 each, in the real military-grade
metal shell version. I know the AMP CPC connectors are quite
affordable. The parts I need would be PT06A-14-18S and
PT06A-14-5S (could be PT06E but those would be more expensive,
I'd guess.)
Thanks,
Jon

There are literally hundreds of different combinations of these military connectors. Vendors typically stock a "kit" of parts and assemble the connector to order. I've never seen a "cheaper" version. You need to either bite the bullet and order the appropriate mating connector or replace the connectors with something more reasonable... One word of caution: The pins in the connectors are "crimp on" and, if you don't have the proper crimping tool (and there are several different ones for different pins...), your chances of successfully attaching the pins are rather slim, too.

I would pay $30 instead of wasting time trying to find them. Are they amphenol or what? I have a junk pile of these connectors too.

The PT02E is a weatherproof connector and a little harder to install. Get a price on a PT02A if you dont need the weatherproof option.

Yes, Amphenol, but I suspect Bendix, Burndy, Cannon, etc. made compatible connectors at one time. This is a motor that may be trashed anyway. It is a brushless servo motor I got on eBay. I have already doped out that it has a standard Renco encoder in it with both the ABZ and commutation signals on it, and that is working. The motor has a LOT of magnetic cogging for a high-end servo motor, or at least I think it is magnetic. It could be Brinelled bearings, but it doesn't seem to feel like that. Badly Brinelled bearings usually feel worse the faster you spin them, this motor seems to get smooth at about 100 RPM. I bought this primarily to test my new brushless servo amp with a big motor, but if it is in good shape I might actually put it on a machine later.
So, I really don't want to spend $70 getting the two connectors for a $30 motor (my eBay cost), when it may need serious repairs.
I have accumulated quite a pile of proprietary crimping tools.

John..if its cogging..its likely to be a stepper rather than a servo.

Same size pins from a different connector and a little epoxy or RTV will suffice to make a connection if you do not need to disconnect it regularly.

Even better -- the right kind of wax or thermoplastic in a hot glue gun and a piece of Mylar film wrapped inside the shell will make a connector which can be used for a while at least. You want something which won't stick to the bottom of the connector or to the walls if it leaks past the Mylar film, so the normal hot glue would not be the best choice. A new nosepiece for the hot glue gun which extends it down into the connector shell will help, too.
But as long as you can find a connector with the right shell and the right insulator, you can change the keying by simply rotating the insulator to the right notch before you assemble it. IIRC, you already found the right shell, but not (yet) the right insulator.
BTW -- Bendix and Deutch (at least) did not make compatible series of connectors. They tended to be rather more specialized connectors. Amphenol and Cannon (at least) made the same series of Mil-std connectors.
Good Luck, DoN.

No, it is a size 42 AC (brushless) servo motor. Very clear on that, It has commutation sensor outputs on the encoder. I suspect that this is not a "slotless" stator design.
