Automotive Feedthroughs

Douglas Electrical Components designs and manufactures a variety of hermetic electrical feedthroughs and connectors for the automotive industry. As vehicles are getting smarter and more connected, our business is designed to support customers from R&D to large scale production. Our sealing technology provides a robust, chemically compatible, hermetic seal between various parts of the vehicle. For example, in LiDAR applications, our electrical feedthroughs hermetically seal the camera to prevent water from penetrating the housing of the sensor and fogging the lens or creating a short. Our products are used to hermetically seal an electrical connection with automotive fuel pumps to ensure a long-lasting connection.  Additionally, we can provide the service of sealing standard automotive and off-road connector designs that cannot meet the existing environmental constraints such as water, dust, and fretting from vibration.

Reduce complexity and weight while hermetically sealing your housing, connector, or feedthrough.

Our automotive electrical feedthroughs are hermetically sealed in different ways.  Douglas Electrical Components can direct cast our epoxy into a customer-designed housing; this can create a low-profile, lightweight assembly that is hermetically sealed to the exact form a customer requires.

Douglas Electrical components offers backpotting connector designs. This process allows us to either hermetically seal non-hermetic connector designs with a variety of integral electrical connection options including pins, sockets, wires, cables, and optical fibers. This service is scalable from Test & Measurement applications in the automotive industry to large scale production. Our hermetic epoxy is not limited to internal combustion engines. Our automotive hermetic connector solutions also span alternative fuels such as hydrogen and hybrid and electric vehicles and charging systems.

Radial O-ring feedthroughs are also popular within automotive platforms.  This seal type is suitable for both vacuum and high pressure, features simple installation, and can integrate redundant sealing.  Customized metal feedthroughs and threads are also available for customers.
