MS/Standa rd
solder contacts
Machined copper alloy contacts in a full range of sizes, with closed
entry socket design in the size 12 and 16 contacts. A heavy silver-
plated finish is deposited on all MS style solder contacts for maximum
corrosion resistance, maximum current carrying capacity and low milli-
volt drop.

* 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.

** Contact ratings as stated are test ratings only. The connector could not with-
stand full rated current through all contacts continuously. Please note that the
electrical data 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 volt-
age, switching surges, transients, etc. can be expected in a particular circuit.
†
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 must determine his own
operating voltage by the application of a safety factor to the above derating chart to compensate for cir-
cuit transients, surges, etc.
