Douglas Electrical Components - Model CircuitSeal -Hermetic Circuit Assemblies

Non-hermetic connectors offer more design options and are lower cost than their hermetic counterparts. Douglas Electrical can hermetically seal a non-hermetic connector and directly integrate it into the circuit board or flex circuit offering a moisture tight seal as well as connector headers and receptacles. CircuitSeal hermetic packages create cost-effective solutions be enabling customers to use smaller mechanical packages to protect electronics.  The mechanical interface can also be customized to simply sit on a hermetic circuit or integrate a housing such as a radial O-ring, jamnut, or bulkhead housing. This adds design flexibility to not only seal the circuit but the mechanical interface that the circuit is designed within including control boxes, housings, and custom assemblies. Our epoxy and the mechanical assemblies can be designed for both vacuum and positive pressure and a wide temperature range.

Hermetically sealed circuit boards are useful for enclosure projects with complex computations as well as sensors, switches, diodes, and capacitors. Potting and sealing effectively blocks and seals against contamination due to outgassing. This hermetic seal technology is also trusted in flexible circuit board connectors and their applications along with hermetic bulkhead applications that require lightweight, compact sealing methods for feedthroughs like missiles, bomb fuses, or even batteries.

Douglas’ hermetic epoxy is certified in various hazardous location designs including explosion-proof, ATEX, and IECEx rated devices, controls, instruments, and more. Partner with Douglas Electrical to encapsulate a circuit designed for hazardous locations.
