MIL-C-38999 Series I, II, III Miniature Circular
KJLY / KJY / KJAY
• High contact density
• 100% scoop proof – Series I and III
• Lightweight Low Profile – Series II
• Environment-resistant
• Operating temperature range from -85°F to
+392°F (-65°C to +200°C)
ITT Cannon’s KJLY, KJY and KJAY connectors are
hermetically sealed and designed to meet the
critical performance and design requirements of
MIL-C-38999. Engineered for high density
circuitry capabilities, these connectors are
designed to operate at temperatures ranging
from -85°F to +392°F (-65°C to +200°C).
They are readily adaptable to both commercial
and space age requirements where size, weight,
scoop proof/low-profile design and high reliability are key factors.
The KJLY and KJAY are designed with a “scoopproof” feature which provides a safety factor in
blind mating applications. The shells also feature
five keyway shell polarization to assure alignment
during engagement. Complete environment sealing is accomplished with an interfacial seal, with
individual raised tapered sealing barriers around
each pin contact, a peripheral seal, and hermetic
sealing.
ITT Cannon’s MIL-C-38999 KJLY, KJY and KJAY
connector series offers these advanced features
to meet the demands of present-day
sophisticated engineering designs.
