Amphenol Aerospace offers the Matrix product line of MIL-DTL-26482, Series 2 Connectors. This series provides a bayonet coupling connector with crimp rear insertable, rear releasable contacts.

Features & Benefits:

  • Medium size, environmentally resistant connector
  • Shells size 8 to 24. Contact sizes 20, 16, and 12.
  • Recommended operating voltage to 1,000 VAC (RMS) at sea level
  • Quick positive coupling assured by 3-point bayonet coupling system
  • 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
  • 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 chamber when mated, providing a positive moisture seal
  • 34 insert patterns available from 3 to 55 circuits
  • Various finishes are available

Service Ratings

Service Rating Recommended
Operating AC Voltage
at Sea Level
Test Voltage AC (RMS), 60 cps
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.

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.

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

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