MIL-DTL-38999

Features and Application

Series III

www.conesys.com sales@aero-electric.com

Features and Application

MIL-DTL-38999 Series III is the newest cylindrical connector

designed for highest performance capabilities used in both

general purpose and severe environment applications.

These connectors feature an improved “one-turn” coupling

system, utilizing self-locking acme thread. Acme threads

provide coupling durability, while thicker wall sections and

greater coupling surface area improve strength and shock

resistance. Blunting of the threads on both receptacle and

plug coupling nut eliminates cross threading.

Elongated mounting holes permit the Series III Connector to

intermount with various existing Mil-spec ﬂange mounted

receptacles, giving it a design replacement advantage.

Wall mount receptacle, jam nut receptacle and straight

self-locking RFI plug are offered in 9 shell sizes and 54 insert

arrangements utilizing M39029 contacts in sizes 22D, 20, 16,

12, 10 power and 8 twinax.

These connectors are available in wide range of shell materials

and ﬁnishes. Aluminum shells are offered in electroless nickel

and olive drab cadmium. Other ﬁnishes such as anodic and

zinc nickel are available upon request to commercial callouts

only. In addition, we offer stainless steel shells (both passivated

and electro-deposited nickel plated) with ﬁrewall inserts, and

for highly corrosive environments, nickel-aluminum-bronze

shells with standard environment-resisting inserts (commer-

cial callouts only).

MIL-STD-1560 Insert Arrangements – Series III connectors

use insert patterns and contacts common to Series I,

making for an easy transition from bayonet to triple-lead,

acme-thread, self-locking coupling.

Metal-to-Metal Bottoming – This feature precludes relative

shell-to-shell motion, which may result in ordinary connector

wear and moisture entrapment.

Lockwiring Eliminated – Self-locking quick coupling plug

eliminates the need for lockwiring.

Firewall Capability - Stainless steel shells in both K and S

ﬁrewall classes are offered.

Universal I/R Tool – A single, expendable plastic tool is used

for both insertion and removal of contacts.

Scoop-Proof Design – Recessed pins in elongated shells

minimize the possibility for contact damage. In a blind

mating application, mating shells cannot “scoop” the pins,

and cause a shorting or bending of contacts.

Closed-Entry Socket Insert – Hard dielectric socket face

has lead-in chamfers for positive alignment of pins (even

partially bent within pre-established limits) with sockets.

Interfacial Pin Insert Seal – Raised moisture barriers

around each pin, which mate into lead-in chamfers of

hard face socket insert, provide individual contact sealing.

Interfacial seal is never touched by service tools.

Elastomer Wire Sealing Grommet – Sealing over a wide

range of wire diameters is assured by a triple wire seal in

each cavity at the rear of the connector.

Superior Contact Stability – Rear release crimp contact

system features a stamped beryllium-copper retaining clip

captivated by molded-in shoulders of each contact cavity in

the insulator. A rear-inserted M81969 plastic tool expands

the tines beyond the shoulder, releasing the contact.

Metric Accessory Thread – Metric thread results in

additional wall thickness giving greater strength and shock

resistance.

S – stainless steel shell, electrodeposited nickel, ﬁrewall

W– aluminum shell, olive drab cadmium over nickel base

BZ* – aluminum nickel bronze shell, std insert

Z*– aluminum shell, zinc nickel ﬁnish

Corrosion Resistance

Classes K, W, BZ* and Z* withstand 500-hour salt spray.

Classes F and S withstand 48-hour salt spray.

Durability

Minimum of 500 mating cycles.

Fluid Resistance

Connectors resist speciﬁed immersions in MIL-PRF-7808,

MIL-PRF-23699, MIL-PRF-5606, M2-V Chevron oil, Coolanol

25, MIL-DTL-83133 (JP-8), MIL-DTL-5624 (JP-4, JP-5),

SAE-AMS1424 Type I, and other solvents and cleaning agents.

Shielding Effectiveness

RFI and EMI attenuation at the speciﬁed frequencies meet

the requirements of MIL-DTL-38999.

●RFI shielding effectiveness of mated connectors with RFI

backshells is measured in a triaxial radio frequency leakage

ﬁxture.

●EMI shielding effectiveness is measured at the interface

of mated connectors and tested by the mode-stirred

technique speciﬁed in method 3008 of MIL-STD-1344.

Voltage Rating

Environmental Seal

Wired, mated connectors with speciﬁed accessories

attached, shall meet the altitude-immersion test speciﬁed in

MIL-DTL-38999.

Shell-to-Shell Conductivity

Maximum potential drop shall not exceed:

●Classes F and S = 1.0 millivolt.

●Class W = 2.5 millivolts, Class K = 10.0 millivolts

Shock and Vibration Requirements

Wired, mated connectors shall not be damaged, nor shall

there be a current interruption longer than one microsecond

when subjected to the following:

Shock

Pulse of approximate half sine wave of 300 G ±15 percent mag-

nitude with duration of 3 ±1 milliseconds applied in three axes.

High Impact Shock

When mounted as speciﬁed in MIL-S-901, grade A, a drop

of a 400 lb. Hammer from 1 foot, 3 feet and 5 feet applied to

connector in three axes, totaling nine impacts.

Vibration

Wired and mated connectors withstand the following

vibration levels:

●Sine vibration where connector samples with simulated

accessory load are subjected to simple harmonic motion

from 10 to 2,000 Hz in three mutually perpendicular axes,

in 20 minute sweeps, for 12 hours in each axis at velocity of

254 mm/sec from 10-50 Hz, displacement of 1.5 mm from

50-140Hz and acceleration of 60G from 140-2,000Hz.

●Random Vibration per MIL-STD-1344, method 205,

test condition V at ambient temperature and test

condition VI, Letter “J” at elevated temperature.

Contact Installation

Instructions

Crimping Contacts

1. Select the appropriate crimp tool and ensure that the

proper crimp head positioner is used.

2. Cycle the tool to be sure the indentors are open.

3. Determine the correct selector setting for the wire size

from the data plate on the positioner (turret head

assembly) and set the selector knob on the crimp tool

to match.

4. Place the contact, mating end ﬁrst, into the tool.

5. Insert the stripped wire into the hollow end of the

contact. Be sure the wire is inserted as far as it will go.

6. Close the tool completely to crimp. Unless the tool is

closed completely, the tool will not release the contact.

7. Remove the crimped contact from the tool. Check the

inspection hole to verify that the wire is fully inserted.

Insertion of Contacts

1. Before inserting the contacts, unscrew the accessories

(clamps, backshells or adapters) from rear of plug or

receptacle. Slide the hardware over the wire bundle in

the proper order for reassembly after all the contacts

are inserted.

2. To assist insertion of contacts, lubricate insulator

(grommet) cavities with isopropyl alcohol. Alcohol will

evaporate and will not leave a conductive ﬁlm. Caution:

Never use any lubricant other than isopropyl alcohol.

3. Place the correct insertion tool on the contact so that the

wire runs along the groove in the tool. (Tool tip will butt

against the shoulder.) Hold the plug or receptacle body

ﬁrmly.

4. Beginning with a center cavity, insert the contact into

the insulator with a slow, even pressure until the contact

snaps into position. Make sure the contact and tool are

held perpendicular to the face of the insert during the

contact installation or the grommet could be damaged.

4.1 If contacts are not inserted all the way prior to

removing insertion tool, do not try to reinsert the

insertion tool. Instead, remove the contact and try

again; otherwise reinserting the insertion tool may

damage the inside of the contact cavity.

5. Remove tool and check the face of the connector for

proper contact installation. Proper installation may also

be checked by pulling back lightly on the wire to make

sure the contact is properly seated.

Completion

After all the cavities have been ﬁlled, slide the hardware back

into position on the connector and tighten.

Extraction of Contacts (Rework)

1. Slide the hardware back over the wire bundle.

2. Select the appropriate tool. Place the wire into the

extraction tool of the pin or socket.

3. Slowly slide the extraction tool down wire into the contact

cavities until the tool tip bottoms against the contact

shoulder, expanding the clip retaining tines. Hold the

wire ﬁrmly in the tool and pull the wired contact and

tool straight out of the rear of the insulator.
