crimp contacts
Machined from copper alloy and silver-plated for maximum corrosion resistance, with a
minimum millivolt drop and a maximum current carrying capacity, the size 16 and 12
socket contacts are of the closed entry design. Crimp contacts are available for all MS
insert arrangements and are identified with an Amphenol
** Contact ratings as stated are test ratings only. The connector could not withstand full
† The 10SL, 12S, 14S and 16S connectors require short contacts.
† Not corrected for changes in density due to variations in temperature.
** No attempt has been made to recommend operating voltages. The designer

given is not an establishment of electrical safety factors. This is left entirely in the
designer’s hands as he can best determine which peak voltage, switching surges,
transients, etc. can be expected in a particular circuit.
must determine his own operating voltage by the application of a safety factor to
the above derating chart to compensate for circuit transients, surges, etc.

* The values listed in Table I represent operating values which include a
generous safety factor. It may be necessary for some applications to
exceed the operating voltages listed here. If this is necessary, designers
will find Table II useful for determining the degree to which the recom-
mended values of Table I can be exceeded.
