MIL-DTL-26500 Features and Application MS2426*/AE66* Features and Application AE66 connectors are widely used on commercial, military and aerospace systems requiring general-purpose, miniature cylindrical bayonet or threaded coupling connectors. Connector Sealing - A pressure seal at the connector interface is accomplished through the aid of a coupling device which compresses the front resilient insulators and thus offers a seal around each contact preventing the passage of moisture through the contact cavity. Rear resilient insulators are designed with a triple wire seal in each cavity to offer positive sealing and prevent wicking of moisture through the connector without the use of external clamping devices or adapters. In addition, a dynamic O'ring seal in the receptacles engages the front of the plug shell when connectors are mated and offers yet another barrier to moisture and contaminants. This family (bayonet as well as threaded) of connectors is offered in wall mount receptacles, jam nut mounted receptacles which incorporate O'ring seals, designed for rear panel "D" hole mounting, and straight plugs. Superior Contact Stability - Front release crimp contact system features a beryllium-copper retaining clip completely encased in a tough dielectric wafer, thus protecting the clip tines from damage. Twenty-one insert arrangements per MIL-STD-1554 are tooled and qualified to MIL-DTL-26500, utilizing 3 to 57 M39029 contacts. Contacts come in sizes 20, 16 and 12, terminating wire sizes from 24 to 12 gauge. Closed Entry Socket Contacts Closed-entry socket contacts facilitate positive mating. MIL-DTL-26500 family offers connectors with bayonet coupling as well as threaded coupling. These connectors are intermateable with correspondingly coupled MIL-DTL-83723 Series III connectors (except shell size 8, threaded coupling only). These connectors are only available in aluminum shells with anodic plating to the MS number. In addition, we offer connectors with passivated stainless steel shells to commercial callouts only. Insert Polarization Alternate insert positions documented in the original specification, positions 1 through 5, are still available (except in shell size 8), but are not approved for new design. These alternate insert clocking positions aid in mating of adjacent connectors having identical insert arrangement. www.conesys.com MIL-DTL- 26500 Shell Polarization - Alternate key/keyway positions prevent cross mating of adjacent connectors having same insert arrangement. - 109 - sales@aero-electric.com MIL-DTL-26500 Performance Specifications MS2426*/AE66* Performance Specifications Shock and Vibration Requirements Wired, mated connectors shall not be damaged, coupling ring shall not loosen, and there shall be no interruption of electrical continuity longer than one microsecond when subjected to the following: Operating Temperature Range Class R: -55C to +200C (-67F to +392F) Class E*: -55C to +200C (-67F to +392F) Shock Mated connectors withstand a pulse of approximate half sine wave of 100 G magnitude with duration of 6 milliseconds applied in each of the three major axes.

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. Crimping Contacts 1. Select the appropriate crimp tool and ensure that the proper crimp head positioner is used. 4.1If 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. 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. 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. 4. Place the contact, mating end first, into the tool. Completion After all the cavities have been filled, slide the hardware back into position on the connector and tighten. 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. Extraction of Contacts (Rework) 1. Slide the hardware back over the wire bundle. 7. Remove the crimped contact from the tool. Check the inspection hole to verify that the wire is fully inserted. 2. Select the appropriate tool. Place tool over the contact on mating side and insert into the cavity. 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. 3. Exert nominal force axially to release retention clip. Spacer sleeve will shoulder at face of insulation when tool is inserted to proper depth. 4. Push extraction plunger to force the contact out of the rear of the insert. 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. 5. Grasp contact or wire and pull the wired contact out of the rear of the insulator. 6. Remove extraction tool axially.

After using the extraction tool, the spacer sleeve should be set forward in the last notch to protect the end of the plunger guide.

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.
