Those extremely harsh environments will also call for extra protection if at all the integrity of the system is going to be adhered to. Hermetic connectors are among the components that will provide that level of protection and ensure that all the elements such as moisture, air, and other contaminants are kept at bay. Every time you go out looking for connectors for any given application, there are a few important features you will need to remember always even as you begin your search.
Select the Shell: There are two major shell types as far as military grade hermetic connector plating is involved: rectangular and circular with sizes typically ranging from 0.25 inches to 3.0 inches. These hermetic connectors can be made using different materials including 300 series stainless steel, cold rolled steel, titanium, aluminum and kovar. Kovar is a cobalt and nickel-based that contains iron while aluminum and titanium based hermetic connectors are extremely lightweight but they equally provide the same quality of sealing as their heavier counterparts.
Select the pins: If you are going to select the right configuration for military grade connectors, you need to determine the number of pins that will be required as well as what kind of orientation will be required. There are different types of pin end shapes that include eyelet, rounded and hooks that come in different ranges. There are different pin materials including Kovar and Copper Cored Kovar, Iconel, stainless steel and molybdenum.
Select the finish: The finish is a very important component since it will protect your hermetic connectors from the environment. Some of the most popularly finished connectors that you will find in the market will include electrolytic nickel connectors, gold plated connectors, copper plated connectors as well as several other electrical connector metal finishing products. While the finishing is meant to protect the hermetic connectors from corrosion, it is also an aesthetic and design element because it makes the entire system look sharp.
Talk to the experts: If you are not able to properly select your hermetic connectors for the kind of application that you have, your best course of action would be to call an expert to advice you; they are well acquainted with these matters.
