MIL-DTL-26482 Hermetic Connectors

MIL-DTL-26482 Series I and Series II connectors, formerly MIL-C-26482, are two series of quick-disconnect miniature circular connectors with three-point bayonet coupling mechanisms used to connect systems requiring power and signal in military and defense environments. These connectors are designed to operate across a wide temperature range of -55°C to 125°C. Douglas Electrical Components provides MIL-DTL-26482 or MIL 26482 standard, series I and II hermetic connectors that ensure reliable performance in harsh environments where standard connectors may fail. They are suited for military and defense applications, vacuum chambers and commercial applications that require helium leak test rates less than 1×10^-7 cc He /seconds.

Offered in smaller sizes than standard connectors, these MIL 26482 standard hermetic connectors feature a three-point bayonet coupling mechanism, with crimp rear insertable and releasable contacts, enabling quick mating and unmating. This bayonet coupling mechanism also makes it an ideal choice for applications located in hard-to-reach or difficult locations. We can provide these connectors in different mounting styles, including wide and narrow flange mounts and shell and contact sizes. It ensures complete flexibility in interconnect system design. In addition to crimped contacts, the MIL-DTL-26482 connectors have various contact styles, including solder and printed circuit boards. These contacts enable easy integration and termination to electronic subsystems and I/O cabling.

It is important to note a few more unique distinctions of Douglas’ capabilities with 26482 connectors.

• Douglas offers more design flexibility – convert virtually any non-hermetic 26842 connector into a hermetic connector design. While glass-to-metal seal connectors have a limited range of hermetic connector options, our technology permits us to hermetically seal all pin and shell sizes.
• Integrate a custom mechanical interface – Douglas can design and manufacture 26482 connectors with a customized mounting interface for vacuum and pressure applications. This can be as simple as a box mount design, threaded face seal or high-pressure radial O-ring feedthrough housing.
• Customized electrical interface – Design a standard pin interface, equivalent receptacle connector, or a completely custom electrical interface directly within the 26482 connector assembly. Douglas can integrate wires, cables, flex circuits and more to reduce footprint, weight, and complexity while increasing design robustness with the electrical interface encapsulated and hermetically sealed.
