Rev A
The continuous current rating for individual contacts cannot be applied directly to the number of
contacts as they are dependent on the thermal and physical properties of the material. System
design shall assure that continuous current rating does not create internal hot spots that exceed the
temperature designated by the connector specification, during steady-state or transient conditions.
Shall remain mated and show no evidence of damage, cracking or chipping.
Probes with spherical ends of .05 inch minimum radius shall be used.
