Dualok Interconnect System



dualok logo
A harsh environment interconnect system with superior electrical performance



Dualok is an enhanced anti-decoupling mechanism that can be used on virtually any cylindrical plug connector and backshell.

The Dualok Interconnect System greatly improves electrical performance in harsh environments while providing a size and weight savings when compared to standard connectors in the same class.

Dualok technology is applied to the plug connector and backshell only and will mate with standard receptacles. 


DUALOK TECHNOLOGY BENEFITS:

SUPERIOR ELECTRICAL PERFORMANCE

  • Better shell-to-shell conductivity
  • Assures EMI protection at high frequencies
  • Minimized contact fretting

SUPERIOR HARSH ENVIRONMENT PERFORMANCE

  • Extreme vibration capabilities at wide temperature range
  • Enhanced corrosion protection with composite materials
  • Reduces relative motion

SIZE AND WEIGHT SAVINGS

  • Lightweight, hybrid composite/metal design
  • Smaller footprint/space savings

Alternate to Cadmium, RoHS-Compliant Platings


DURMALONTM - AMPHENOL'S ANSWER TO EU RoHS/ELV/CADMIUM FREE RESTRICTIONS ROHS Platings
Commercial, industrial & military markets are rapidly moving away from restricted materials such as Cadmium (Cd) & Hexavalent Chromium (Cr(VI)). Both of these restricted materials are toxic and known carcinogens. Amphenol is offering an alternative finish that complies with all customer requirements tied to these specifications. MIL-DTL-38999, Rev L has established new service classes as alternative finishes addressing these requirements for Cadmium replacement. Amphenol is using this and European Union Directive 2002/95/EC RoHS (Regulation of Hazardous Substances) as a guide to qualification for all domestic, global, commercial, industrial, & military specifications requiring the reduction or elimination of these restricted materials. Amphenol has qualified Durmalon, with internal part number coding “DT” finish, which meets or exceeds the 38999 designated class “T” finish, Nickel Fluorocarbon Polymer. Durmalon is also EU RoHS compliant and is Cadmium free, Lead free , and Hexavalent Chromium free. Cadmium has been applied to numerous components of land, sea and air weapon systems and NASA systems for many years as it provides sacrificial corrosion protection and excellent lubricity for threaded applications.

THE DEFENSE LOGISTICS AGENCY (DLA) HAS ADDED THE FOLLOWING CADMIUM ALTERNATIVE FINISHES TO MIL-DTL-38999, REV L (AND OTHER CONNECTOR SPECS):

  • Nickel Fluorocarbon Polymer
  • Zinc-Nickel


Matrix MIL-DTL-26482 (2)



C26482Amphenol broadens their Miniature Circular Family of Connectors with the addition of the Matrix® Product line of MIL-DTL-26482 series II connectors. The Matrix MIL-DTL-26482 series II provides a bayonet coupling connector with crimp rear insertable, rear releasable contacts.

 FEATURES AND BENEFITS

  • Medium size, environmentally resistant connector
  • Recommended operating voltage to 1,000 VAC (RMS) at sea level
  • Quick positive coupling assured by 3 point bayonet coupling system
  • Visual confirmation of complete coupling
  • Eliminates mismating by the use of five key/keyway design
  • Insertion and removal of contacts from the rear of the connector assures no damage to the front that might affect the sealing characteristics
  • Utilizes same standard qualified rear-release type plastic tool for contact insertion and removal
  • Contacts are qualified to SAE AS39029 requirements – BIN coded (three color bands), and are crimped with standard crimp tools per MIL-C-22520
  • Grommets are constructed of tear-resistant elastomer and experience no degradation when exposed to a broad range of fluids
  • Sealing over a range of wire diameters is assured by a triple webbed grommet at the rear of the connector
  • Closed entry socket side of the insert is designed with a lead-in chamfer and a hard face that will accept a pin contact bent within pre-established limits
  • Elastomer interfacial seal on the pin side has raised barriers around each pin which displace into the socket chamfer when mated, providing a positive moisture seal

PERFORMANCE SPECIFICATIONS
SERVICE RATINGS**

Service Rating Recommended Operating AC Voltage at Sea Level Test Voltage AC (RMS), 60cps
Sea Level 50,000 ft. 70,000 ft 110,000 ft.
I 600 1,500 500 375 200
II 1,000 2,300 750 500 200

** Service Rating is comparable to MS rating A. Miniature connectors rated Service Rating I will provide a minimum flashover voltage at sea level of 2,000 volts AC (RMS). Service Rating II is comparable to MS Service Rating D, and will provide a minimum flashover voltage of 2,800 volts AC (RMS) at sea level. Please note that the electrical data given is not an establishment of electrical safety factors. This is left entirely in the designer’s hands, as he can best determine which peak voltage, switching surges, transients, etc. can be expected in a particular circuit.

OPERATING TEMPERATURE RANGE
–65°C (–85°F) to 200°C (392°F)

ENVIRONMENTAL SEAL
Wired, mated connectors with the specified accessory attached will meet the altitude immersion test specified in MIL-DTL-26482.

DURABILITY
Minimum of 500 mating cycles.

SHOCK AND VIBRATION REQUIREMENTS
When tested as follows, the connector shall sustain no
physical damage, or electrical discontinuity exceeding
one microsecond.

SHOCK:
Pulse of an approximate half sine wave of 300g magnitude with duration of 3 milliseconds applied in three axes.

VIBRATION:
Sixteen hours of random vibration having a range of 50 to 2,000 Hz with a 41.7G peak level.
