  • Clip-on inductive pulse pick-up
    Patent number: 4005380
    Abstract: The halves of a ferrite core respectively set in the jaws of a pick-up clip are held in plastic holders loosely mounted in the respective clip jaws with compression springs between the holders and the jaws that are weaker than the spring that pulls the clip jaws together. This arrangement enables the core halves to accommodate to each other to produce a flush fit and reduces the impact on closing the clip which the main spring would otherwise produce. A conducting coating is provided for electrical shielding against stray fields.
