42. POWER CONTACTS. Power contacts are used to
connect single conductor wire through connectors.
The power contacts range from size 10 through 22M
and are of crimp, rear release design. Contacts are
listed by size. Match the required size to connector
pin contact part numbers are listed along with
corresponding color bands (Table 2).

44. THERMOCOUPLE CONTACTS. Temperature
sensing systems utilize two dissimilar metal conductors
with matched lengths. When joined at the point
temperature will be sensed, a voltage difference
develops. This voltage is directly proportional to
temperature change. Thermocouple contacts listed
