5.Materials. Rugged connector housing may be constructed of plastic, aluminum or brass; the material selected has an impact
on reliability, weight, and cost. Brass connectors with nickel/chrome
plating are wear resistant
and have longer life cy-
cles than other materials.
are more lightweight,
while plastics are ideal
for limited reuse and
disposable conditions. If you are considering plastic, adequate testing
is advised to make sure it will withstand the wear-and-tear of the
application. In medical equipment, make sure the connector can with-
stand any sterilization processes that may be required. Stainless steel
is a high performance choice for corrosive environments or some food
6.Reliability. Reliability is another factor to consider: How many times will the end user connect and disconnect the device? If a
high number of mating cycles are predicted, look for a rugged connector suited to 5,000 to 10,000+ cycles. Dependability over time is
essential is situations that may put lives at risk, such as in medical or
7.Miniaturization. As equipment and devices of all kinds are getting smaller and more lightweight, it’s possible to design a
connector today that would have required two or three connectors
only a few years ago. If you are considering a miniature connector,
make sure that it can handle your voltage and current requirements.
Small connectors are often difficult to terminate, so miniature plugs
and receptacles are sold pre-wired to maximize reliability.
8.Raw cable and assemblies. When you choose the raw cable and cable assembly, consider the connector and the cable together to
make sure they are compatible. As connectors get smaller, they may
not be suitable for use with larger cables. A critical part of choosing
cable for rugged applications is the cable jacket material. Polyurethane
is an ideal candidate due to its high cut strength and its resistance
to oils, coolants, and grease. Non-halogen and flame retardant grades
are also available. If the cable is going to a high stress or high flex
environment, consider using alloy conductors instead of copper. They
offer higher tensile strength (~ 33 percent) and high flex life with a
moderate increase in DC resistance (~25 percent).
Once you’ve developed a specification checklist, make sure the
manufacturer of the rugged connector you’re considering provides
dependable service, reliable delivery and expert engineering support.
Many standard connectors are available off the shelf, but customized
or modified solutions can also be developed to suit the unique needs
of your application. Regardless of your specs, rugged connectors can
help improve performance and functionality, while contributing to a
design that’s lightweight, easy to handle, and reliable. ECN
