● 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.
● Lock wiring Eliminated
● Self-locking quick coupling plug eliminates the need for lock wiring.
● 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.
● Twinax Contacts
● Aero Electric is Qualified to make and supply M39029/90-529 and M39029/91-530 size 8 Twinax contacts used in 38999 III connectors.
● Self-locking, RFI grounding plug
● Aluminum shell, olive drab cadmium over electro less nickel base
● Shell Size "B
