ARINC 404 & 600 Connectors

ARINC 404 & 600 Filter Connectors


Amphenol CIT ARINC 404 filter connectors feature the complete line of standard ARINC layouts and meet the applicable performance and environmental portions of the ARINC and SAE specifications. These connectors provide the key interface for rack and panel avionics equipment. As with all avionics boxes, signal integrity is paramount and filtering is a must. Due to the rack and panel mating ARINC 404 connectors are used in commercial and military aircraft, including helicopters. They are also found in in-flight instrumentation, flight simulators and radar systems. Combining power and signal contacts are common to this family.


The ARINC 600 family of connectors offers higher contact counts, shell polarization, power and signal contacts, and low mating forces. Amphenol CIT designs feature a modular approach using standard shells and inserts with a filtered backpack. Amphenol CIT ARINC 600 connectors feature the complete line of layouts and meet the applicable performance and environmental portions of the ARINC specifications. Following the ARINC document, Amphenol CIT offers:

  • Size 1 Shells: 3 gang-style, housing the narrower 11.1 mm inserts
  • Size 2 and 3 Shells:  Standard 26.34 mm wide inserts with 3 and 6 gangs, respectively
  • A wide variety of insert arrangements that include all standard contact sizes like coax, Quadrax, and fiber optic
  • Contact arrangements including a variety of contact sizes ranging from size 22 signal contact down to size 1 coaxial contacts. Sizes 5, 8, 12, 16, and 20 are also available.

This rack and panel family was designed for high density with the potential of up to 800 contacts in one connector mating. Like any box-mounted receptacle, these Amphenol CIT connectors offer the perfect solution for housing the EMI filter to keep stray noise out.
