Hi:

I have a few hundred AMP cannon plug connectors leftover from my Boeing 737 project. These were removed from a real 737-300, left behind after most of the avionics modules were removed.

These are potentially useful to builders out there who are interfacing real avionics and instruments. Having these connectors allows a builder to retain the existing connector on the back of the unit and also facilitates reverse engineering of the unit's functionality.

I have multiple numbers of every common connector used on the back of Boeing avionics. The part numbers of almost all of them begin with MS24266, then follows a common naming convention which next indicates a shell size, then the number of contacts, a letter indicating whether the contacts are female sockets or male pins, and finally a number or letter designating the keyway pattern. For example:

MS24266R18B31S7

denotes a connector with 31 pins that are sockets.

MS24266R22B55P8

denotes a connector with 55 pins that are pins.

If you have a real OEM Boeing avionics unit, you can read the connector number off the back of the unit to determine what kind of mating connector you need. These typically start with MS24264 and follow the same naming convention. To determine the mating connector, simply exchange the MS24264 for MS24266, and change the P in the next to last position for an S (this indicates a connector with sockets is needed for a unit with a pin connector).

AMP also uses a different nomenclature that contains the same information. For example, I have a real Boeing LE flaps/slats indicator with a connector on the back labelled:

ZZB-AC-1722-55P

which indicates a bayonet style, aluminum shell, square flange mount, size 22 connector with 55 males pins. There is no number or letter after the 'P,' which indicates the 'normal' keyway.

The mating MS24266 connector would be:

MS24266R22B55SN

the next to last letter indicates female sockets, and the N at the end indicates the normal keyway.

This is explained on page 7 of the attached pdf, which is the AMP catalog.

Each one of these used connectors have a number of pins or sockets with a length of 3-6 inches of wire coming out. New pins (as well as the crimping tool) are expensive, so for my build I just reused the sockets or pins by splicing onto the ends of the leftover length of wire with butt splices or soldering. The pin insertion/removal tools can be found easily online and are used to reposition the old contacts. None of the connectors have all positions filled, but if you tell me how many you need I will include them.

Here is a partial list of the connectors I have available for sale. If you don't see something you need, ask me because I haven't inventoried everything yet.
