I also want to thank the spring pin companies, IDI , ECT , CCCP, and others, for samples, pricing, and specifications. We will not use this type pin. It's designed to be compressed vertically. I've heard from many experts in the field around the world about this type spring loaded pin technology, and they agree it's not the best way to go for this application. We will use leaf spring style terminal pins.
Truth is, the spring pins are fine.
It's just not the best choice for a Pfranc plug. They cost a lot because the spring pins are very expensive and distribution channels are expensive. The cable is placed under the unit and slid upward. The pins are not pressed in vertically but compressed because of the horizontal movement of the plug. They first hit the curved part of the plastic case of the eMap below the receiver, which is actually the battery door.
