MSD's Non-Magnetic pickups are engineered for extreme applications. In fact, this pickup was designed and tested on 300+ mph top fuel dragsters. To live up to MSD's demanding expectations in these extreme applications, MSD engineers decided to design and build these pickups in-house. This way they can control every aspect of their assembly and quality. Each pickup is hand wound on special bobbins and terminated on a tinned conductor, Teflon jacketed wiring. These wires are also routed through a strain relief for protection. This assembly is then installed into the precision housing and is potted with a fracture resistant epoxy compound. To ensure that the windings are entirely encased in epoxy the pickups undergo a vacuum procedure to remove any air inside the housing. All of these procedures are necessary to produce the strongest, most reliable Non-Magnetic pickup available.
