D38999 Connectors > D38999 Series III

Description

Designed for performance, the MIL-DTL-38999 Series III (also referred to as D38999, MIL-C-38999, 38999) connector is the universally accepted leader in compact, lightweight cylindrical connector technology. It offers the highest performance capabilities for both general duty and severe environment applications.

• Lightweight, compact, high contact density
• Most popular cylindrical for high performance and environmental resistance
• The most sophisticated cylindrical connector to meet military aerospace demands under severe conditions
• Wide variety of customer options

Series include

• Firewall Class RK and RS with Stainless Steel shells
• New Clutch-Lok MTV 38999 for high vibration environments
• Hermetic Receptacles
• ESD Protection with Faraday cage
• New 38999 Power connectors with high amperage contacts
• Space application connectors
• PCB and compliant press-fit terminations

Applications

High performance general duty and severe environmental applications.

• Military Aerospace
• Commercial Aircraft
• Space Applications
• Military Vehicles
• Medical Equipment

Standard Requirements

MS versions meet or exceed MIL-DTL-38999 Series III. Lanyard release style meets MIL-STD-1760 requirements.

Coupling / Mounting

Threaded coupling. Quickly and completely mate in one 360° turn of the coupling nut. Self locking - lockwiring is eliminated. 5 key/ keyway polarization eliminates mismating. Universal mounting holes for front or rear mounting. Locksmith metal keying to aid in blind mating.

Contact Terminals

Crimp termination. Recessed pins (100% scoop-proof feature minimizes contact damage). Also available with PCB and compliant press-fit termination.

Performance / Environmental Effect

Operating temp. from –65°C to +200°C. Superior EMI shielding is achieved through the combination of grounding fingers and solid metal to metal mating. IP67 rating for environmental sealing. Corrosion resistance: shells of stainless steel or cadmium over nickel plating withstand a 500 hr. salt spray exposure. Operating voltage to 900 VAC (RMS) at sea level.

Optional Features

• 6 shell styles and over 50 insert patterns.
• Hermetic seal (glass fusion) receptacle styles available.
• Stainless Steel Firewall, Class K styles available.
• Variety of shell finishes.
• Twinax, coax, triax, filter contacts and fiber optic termini options.
• Ground plane versions.
• Fail-safe lanyard release plug style versions.
• Printed circuit board contacts, wire wrap and compliant press-fit contacts.
• ESD (Electrostatic Discharge Protection) available with use of Faraday cage to shunt high voltages.
• Flex termination assemblies for attachment to PCB boards.
