Custom O-ring sealed power feedthrough stud and flange-mount feedthrough
Flange-mount crimp power feedthrough with square flange and copper crimp terminal

Custom High-Current Power Feedthroughs

Designed to your vessel · 450–750 A examples · to +170 °C

Besides the standard studs, we design power feedthroughs to your wall thickness, thread, current and temperature. Two examples: a 750 A O-ring sealed stud with M33 × 2 body thread, and flange-mounted crimp feedthroughs for 450 A and 600 A with PPS insulating covers, rated to +170 °C and 5000 VAC.

  1. Send your requirements

    Part number, drawing, pin-out or a short description of your application.

  2. Configuration and quote

    Our engineers match the configuration and reply with a drawing and quotation.

  3. Samples

    Samples are built to order. The minimum order quantity is 10 pieces, and samples and production orders each take 4–8 weeks. Third-party testing to your specification is available on request.

  4. Your approval

    You test the samples in your own equipment and approve them.

  5. Series production

    Production follows the approved sample configuration, with machining, molding, plating and assembly in our own Shenyang factory.
