These connectors are available in wide range of shell
materials and finishes. Aluminum shells are offered in
electroless nickel, olive drab cadmium and black anodic.
Other finishes such as zinc cobalt are available upon request
to commercial callouts only. In addition, we offer passivat -
ed stainless steel shells with standard environment-resisting
inserts (commercial callouts only), and for highly corrosive
environments, nickel-aluminum-bronze shells with standard
environment-resisting inserts (commercial callouts only).
Universal I/R Tool ? A single, expendable plastic tool is used
for both insertion and removal of contacts.
Insert Polarization ? Alternate insert clocking positions
aid in mating of adjacent connectors having identical insert
arrangement.
