MIL-DTL-38999 Features and Application Series II Features and Application 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. MIL-DTL-38999 Series II connectors feature a bayonet coupling mechanism with lower profile design and rear-removable crimp contact retention system. 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. Reduction of both size and weight were achieved through the use of thinner shell walls and length restrictions. These design restrictions reduced the RFI attenuation characteristics and the “scoop” protection, while yielding an excellent general purpose, lightweight connector. Compared to Series I, Series II connectors achieve up to 20% reduction in mated pair length, up to 39% reduction in outside diameter and up to 40% reduction in weight (128 pin mated pair). This family of connectors is offered in six receptacle-mounting styles. They include square flange receptacles, for both front and rear panel (wall) mounting; square flange receptacles, for both front and rear panel (box) mounting; square flange receptacle with extended grommet, for front of panel (box) mounting; and jam nut receptacles which incorporate “O” ring seals, designed for rear panel “D” hole mounting. 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. Shell Polarization – Alternate key/keyway positions prevent cross mating of adjacent connectors having same insert arrangement. Plugs are available in two designs, with and without RFI grounding. Fifty-two insert arrangement per MIL-STD-1560 are tooled and qualified to MIL-DTL-38999 Series II, utilizing 3 to 128 M39029 contacts. Contacts come in sizes 22D, 22M, 22, 20, 16 and 12, terminating wire sizes from 28 to 12 gauge. These connectors are available in wide range of shell materials and finishes. Aluminum shells are offered in electroless nickel, bright cadmium, anodized, and olive drab cadmium. Other finishes such as zinc cobalt are available upon request to commercial callouts only. In addition, we offer passivated stainless steel shells with standard environment-resisting inserts (commercial callouts only). Universal I/R Tool – A single, expendable plastic tool is used for both insertion and removal of contacts. www.conesys.com – 22 – sales@aero-electric.com 38999 S II These connectors were designed for military and commercial applications where the prime requirements are lower profile and lighter weight. MIL-DTL-38999 Performance Specifications Series II Performance Specifications Shell-to-Shell Conductivity Maximum potential drop shall not exceed: • With RFI spring fingers, finish F = 1.0 millivolt, while finishes A and B = 2.5 millivolts. • Without spring fingers = 200 millivolts. • Finish C = nonconductive.

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. 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. 4.1 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. 4. Place the contact, mating end first, into the tool. 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. 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. Completion After all the cavities have been filled, slide the hardware back into position on the connector and tighten. 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. 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. 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.

Beginning with a center cavity, insert the contact into the insulator with a slow, even pressure until the contact snaps into position.
