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.

REQUIREMENTS
Unmated receptacles shall be subjected to 10 cycles of thermal shock per Step 1 and Step 2 of MIL-C-38999.
The connector shall be mounted in a suitable test apparatus. A pressure differential of 1 atmosphere shall be applied across the connector. A suitable means to determine the leakage through the connector of air or other pressurizing gas, containing not less than 10 percent helium by volume,
shall be employed while the specified pressure is applied. There shall be no evidence of leakage in excess of 0.01 micron ft3/h ( x 10-7 cm3/s).
For qualification testing, mating halves shall be coupled and uncoupled; the forces or torques which must be applied to facilitate full coupling and
uncoupling shall be measured and recorded. For quality conformance, suitable gages may be used instead of the appropriate counterparts. The coupling torque for mating and unmating of counterpart connectors shall meet the requirements of Table III, paragraph 4.7.6 MIL-C-38999.
Insulation Resistance at ambient temperature — Unmated connectors shall be tested as specified in method 3003 of MIL-STD-1344. Connectors
shall be mated when testing after altitude immersion and humidity. The insulation resistance between any pair of contacts and between any contact and the shell shall be greater than 5,000 megohms. Insulation resistance after altitude immersion shall be 10,000 megohms minimum. Insulation resistance after humidity shall be 100 megohms minimum.
Insulation Resistance at elevated temperature — Unmated connectors shall be tested as specified in method 3003 of MIL-STD-1344. Applicable
elevated temperature for 30 minutes:
Finish D, 150° +5/ -0°C; E; 200° +5/ -0°C.
Measurements shall be made while the connectors are still in the chamber at the specified temperature. The insulation resistance between any
pair of contacts and between any contact and the shell shall be greater than 200 megohms.
Dielectric withstanding voltage at sea level — Wired, unmated connectors shall be tested in accordance with Method 3001 of MIL-STD-1344.
Connectors shall be mated when testing after altitude immersion and humidity. The magnitude of the test voltage shall be as specified in Table XIV.
The test voltage shall be maintained at the specified value for 2 seconds minimum.

Dielectric withstanding voltage at altitude — Mated connectors and unmated connector halves with pin contacts shall be tested in accordance
with method 3001 of MIL-STD-1344. The magnitude of the test voltage shall be as specified in Table XIV. The test voltage shall be maintained at
the specified value for 2 seconds minimum. Only the engaging faces of hermetics shall be subject to the high altitude. The rear face shall be suitably
protected. The chamber shall be evacuated to each of the specified altitude pressure equivalents listed below.

When tested as specified in 4.7.10.1 or 4.7.10.2 connectors shall show no evidence of flashover or breakdown.
Contacts of mated connectors shall be tested in accordance with method 3004 of MIL-STD-1344. Contacts in the mated condition shall meet the
contact resistance requirements of Table IV, paragraph 4.7.13 MIL-C-38999. Lead resistance may be included in the measurement.

For qualification only, wired and mated connectors shall be subjected to the applicable test(s) specified. Connectors shall be mounted on the vibration table by normal means. All contacts shall be wired in a series circuit with 100 milliamperes maximum current flow through the series circuit during vibration. Connectors shall be continuously monitored for all discontinuities. A detector capable of detecting any discontinuities in excess of
1 microsecond shall be used.
Wired and mated connectors shall be subjected to the applicable test specified. Connectors shall be mounted by normal means and held together
by normal coupling means. All contacts shall be wired in a series circuit with 100 milliamperes maximum current flow through the series circuit during shock. Connectors shall be monitored for any discontinuities. A detector capable of detecting any discontinuities in excess of 1 microsecond shall
be used.

Light Weight Sealed Hermetic Connector
ITT Cannon’s new KJAYA is a lightweight aluminum shell connector that provides low pressure sealing of 0.01 micron cubic feet per hour for a pressure differential of 15 PSI.
The KJAYA hermetic utilizes a special sealing materials and the connector is
designed to meet the water immersion requirements at a depth of 1 meter. It is
a low cost aluminum based connector that also provides a reduction in weight.
The KJAYA utilizes copper based contacts with a reduction in resistance when
