Utilizing high reliability air bag initiator technology and a variety of output configurations, we can create the ideal product for you. Contact us with your technical specifications.

PDDPower Disconnect Devices

In order to support enhanced safety features of modern vehicles, SDI has developed a Power Disconnect Device (PDD). The PDD provides high reliability, high speed interruption of electrical circuits. In conventional vehicles PDD’s are used as part of the safety system battery/starter system to terminate battery power in the event of a serious accident to mitigate chances for igniting spilled flammable materials. In the emerging Hybrid and Electric vehicle markets, PDD’s are used in a variety of applications to protect electric circuits and prevent damage to expensive battery packs.

InitiatorsComposite Molded Assemblies

As the continuing need for lower cost components increases the challenge to the automotive industry, SDI has responded with innovative design solutions, which take advantage of our considerable plastic molding expertise. Our Composite Molded Assembly (CMA) technology can help lower your total product cost by molding certain design features into the initiator assembly, thus replacing expensive machined components. This technology also has the potential to further reduce cost by eliminating components in certain applications.
