MIL-DTL-26482 Features and Application Series 2 Features and Application MIL-DTL-26482 Series 2, bayonet coupling, rear-removable crimp contact connectors were designed as an upgrade to MIL-DTL-26482 Series 1. Series 2 connectors are intermountable and interchangeable with both solder and front-release crimp Series 1. They are also identical to the inactivated MIL-DTL- 83723 Series I connectors. Series 2 connectors are widely used on commercial, military and aerospace systems requiring general-purpose, miniature cylindrical bayonet coupling connectors. This family of connectors is offered in 4 receptacle-mounting styles. They include narrow flange wall mounting receptacles, wide flange wall mounting receptacles, cable connecting receptacles and jam nut mounting receptacles which incorporate "O" ring seals, designed for rear panel "D" hole mounting. 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. Plugs are available in two designs, with and without RFI grounding. 26482 S 2 Thirty-three insert arrangements per MIL-STD-1669 are tooled and qualified to MIL-DTL-26482 Series 2, utilizing 3 to 61 M39029 contacts. Contacts come in sizes 20, 16 and 12, terminating wire sizes from 24 to 12 gauge. These connectors are available in wide range of shell materials and finishes. Aluminum shells are offered in electroless nickel, olive drab cadmium and black anodic. 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), and for highly corrosive environments, nickel-aluminum-bronze 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. Insert Polarization - Alternate insert clocking positions aid in mating of adjacent connectors having identical insert arrangement. www.conesys.com - 108 - sales@aero-electric.com MIL-DTL-26482 Performance Specifications Series 2 Performance Specifications Durability Mated connectors withstand a minimum of 250 mating cycles for RFI plug (MS3475) and 500 cycles for standard plug (MS3476).

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. 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. 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. 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.

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. MIL-DTL-26482 Series 2 Polarization, Insert Availability & Contact Information per MIL-STD-1669 Polarization (Insert Clocking) 1. In the normal insert clocking position (position N), the insert centerline coincides with the centerline of the master keyway (key) of the shell: L = 0. L MASTER KEYWAY (KEY) OF A SHELL 2. In the alternate clocking positions (W, X, Y and Z), the pin insert (viewing from mating side) is rotated clockwise relative to the centerline of the master keyway (key) of the shell. 3. The socket insert is rotated counter-clockwise. 4. Plugs have keys; receptacles have keyways. INSERT VERTICAL CENTERLINE Note: Be careful with alternate positions.
