Amphenol Quadrax Contacts

Amphenol Quadrax Contacts

DURABLE HIGH SPEED CONTACTS

PEI-Genesis offers Quadrax contacts manufactured by Amphenol. Quadrax pins are designed to meet ASTM E595 outgassing standards for aerospace applications. These high speed/frequency contacts feature a rugged outer wall for increased durability, gold plated finish, and crimp termination to protect four strategically spaced inner contacts that form two 100-150 Ohm matched impedance differential pairs. When these contacts are matched with a MIL-DTL-38999 Series III or ARINC style connector, they form a high speed connector suitable for use in harsh environments. Amphenol Quadrax contacts can handle up to 1.25 GHz of bandwidth and data transfer rates in excess of 2.5 Gbps. Available in size 8 crimp termination style or with PC tails. 1

FEATURES

AMPHENOL QUADRAX CONTACTS – FEATURES


Amphenol Quadrax Contacts offer several advantages for high data transfer rates, low power consumption and excellent EMI compatibility:

  • Four strategically spaced inner contacts form two 100 or 150 Ohm matched impedance differential pairs

  • Outer contact has rugged wall section for durability

  • Available in size 8 with PC tails

  • Requires modification of MIL-DTL-38999 connector to accommodate keyed contacts

Amphenol Quadrax Contacts for Printed Circuit Board Attachment – Available for MIL-DTL-38999 Series III Circular connectors with straight PC tail termination and with compliant pin termination. These provide the ideal solution for bringing high speed data transmission to the board.


Amphenol Quadrax Contacts for Rectangular Board Level Connectors – Incorporate the same size 8 Quadrax PCB contacts as used in circular 38999 connectors.

  • 0.025 ±0.002 PTH Quadrax contact

  • 0.040 ± 0.003 PTH shell grounding

  • Accomodates backplane 0.125 inch min. thickness

  • Consult Amphenol Aerospace for availability of additional connector configurations
