MIL-DTL-38999 SERIES I
Deustch/TE Connectivity DJT series MIL-DTL-38999 series I connectors offer high density contact arrangements in a miniature metal circular connector. DJT connectors meet MIL-38999 and were originally designed as military and aerospace components. The Deutsch DJT series is now being used in many applications requiring extremely reliable interconnections. These Deutsch connectors are quick-mating, environmentally-sealed, triple-lead threaded, have a self-locking coupling, and are EMI-RFI-shielded. A variety of D38999 backshells are available. For full product details on the Deustch DJT series MIL-DTL-38999 series I connectors, please see the specifications below.

STANDARD MIL-SPEC ACCESSORIES
Heat Shrink Boot Adapters Designed for use with straight or right angle shrink boots. A knurled rear section with a boot groove provide an excellent surface for the boot to grab the metal endbell. Available with lock wire and drain holes. See Heat Shrink Boots on pages 258-260. Extender Backshell with cable clamp Non-environmental, designed for use with jacketed cable, allows extra space to break out the wires and still provide stain relief clamping to the outside of the cable jacket. Environmental Shielded Endbell This EMI/RFI shielding environmentally sealing endbell features a standard style cable clamp with gland seal at the end of and extender style backshell. Non-Environmental Shielded Endbell This EMI/RFI shielding non-environmentally sealing endbell features a standard style cable clamp.

Banding adapters utilize a band of metal that fastens and grounds cable shields to the outside of endbells. This method of terminating shields has advantages in that they typically use tools to tighten trim the bands. These tools make the termination tight, repeatable, reworkable (if you make a mistake just cut the band off and start again) and facilitates service. Banding adapters help lower the total applied cost by having simpler designs that have fewer parts with uncomplicated assembly procedures. Wire Seal Compression Nut

DEUSTCH/TE CONNECTIVITY DJT SERIES MIL-DTL-38999 SERIES I WIRE STRIPPING
Strip insulation from end of wire to be crimped. (See table for proper stripping dimensions.)
Do not cut or damage wire strands.
All dimensions in inches (millimeters in parentheses)
DEUSTCH/TE CONNECTIVITY DJT SERIES MIL-DTL-38999 SERIES I CONTACT CRIMPING
Correct
Incorrect
STEP 1: Insert wire into rear of contact. Wire insulation must press against rear of contact. Wire must be visible through inspection hole.
STEP 2: M22520 series crimp tool and locator is recommended. Click here for choice of turret head and selection setting according to contact size, part number and wire gauge size.
STEP 3: Insert contact and wire into tool jaws. To crimp, squeeze handles together fully until ratchet releases and allows handles to expand; otherwise, contact cannot be extracted from tool jaws. Maintain slight insertion pressure on wire while crimping contact to wire.
DEUSTCH/TE CONNECTIVITY DJT SERIES MIL-DTL-38999 SERIES I CONTACT INSERTION
STEP 1: Remove hardware from plug or receptacle and slip over wire bundle in proper order for reassembly.
STEP 2: Using proper plastic or metal insertion tool for corresponding contact, position wire in tip of the tool so that the tool tip presses against the contact shoulder.
STEP 3: Press tool against contact shoulder and, with firm and even pressure, insert wired contact and tool tip into center contact cavity.
STEP 4: When contact bottoms, a slight “click” can be heard as tines of metal retaining clip snap into place behind contact shoulder.
STEP 5: Remove tool and pull back lightly on wire to make sure contact is properly seated. Repeat operation with remainder of contacts to be inserted, beginning with the center cavity and working outward in alternating rows.
STEP 6: After all contacts are inserted, fill any empty cavities with wire sealing plugs. Reassemble plug or receptacle hardware.
Note: DTS Series Shown
DEUSTCH/TE CONNECTIVITY DJT SERIES MIL-DTL-38999 SERIES I CONTACT EXTRACTION
STEP 1: Remove hardware from plug or receptacle and slide hardware back along wire bundle. STEP 2: Using plastic or metal extraction tool with proper color code corresponding to contact size, place wire in tool. STEP 3: Insert tool into contact cavity until tool tip bottoms against the contact shoulder, expanding clip retaining tines.
STEP 4: Hold wire firmly in tool and extract wired contact and tool. Repeat operation for all contacts to be extracted. STEP 5: Fill any empty cavities with wire sealing plugs. Reassemble plug or receptacle hardware.
Note: DTS series shown.
