These are the best multi pin connectors on the market. The AMP gold plated pins are far more reliable than the Whirlwind MAss or the Veams and the metal versions are much more solid the the more common plastic shells while still accepting the same pins and sockets. These are sold without electrical contacts. I have eight cable ends with Kellums grips, six cable ends with stock cable clamps and twelve panel mount connectors. $15 each for the Kellums grip versions, $10 each for the other parts all plus shipping. Make me an offer for all of the set. If you are new to AMP multi pins the electrical contacts are bought separately from electronics suppliers, crimped onto the end of the cables ( no soldering which is part of the reliability ) and inserted into the connector face. You'll need the pins, sockets and a crimp tool to make a project of it.
