DELIVERING QUALITY PERFORMANCE IN DEMANDING ENVIRONMENTS

Qualified to MIL-DTL-38999 standards, Conesys D38999 Series III connectors provide excellent durability and performance in any environment. D38999 Series III connectors feature a one-turn coupling system with a self-locking acme thread for improved strength and shock resistance.

Elongated mounting holes permit the Series III Connector to intermount with various existing Mil-spec flange mounted receptacles, giving it a design replacement advantage.

Conesys D38999 Series III connectors are built to withstand a minimum of 500 mating cycles, and their proven corrosion resistance, fluid resistance and EMI/RFI shielding makes them ideal for general exposure and applications with harsh environmental exposure.

Features and Benefits

• 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
• Lockwiring Eliminated - Self-locking quick coupling plug eliminates the need for lockwiring
• 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 seals are 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. Please consult factory even when needing to buy just the contacts
