Description:

Amphenol Low Mating Force Rectangular Connector series is one of the highest performing board-level connectors in the world- with proven performance on the ground, in the air, and at sea. This series utilizes the B3 brush contact system known for low mating force, stable electrical performance in high vibration and extended service life.

Features & Benefits:

  •  0.100 inch center to center, square grid contact spacing
  • Application flexibility (parallel boards, perpendicular boards, wire to  board, end to end boards, card extenders)
  • 2, 3 and 4 row contact arrangements with 10 to 100 contacts per   row in one contact per row increments
  • Military versions meet MIL-DTL-55302/166 through /172
  • Termination versatility; straight & 90° PCB stud, wire wrap & crimp

Brush Contact Technology

 

Brush Contacts vs. Conventional Pin and Socket Contacts

Brush Contact Innovation

  • Multiple contact interfaces - Strands of high tensile wire are bundled together to form brush-like contacts. By intermeshing two multi-strand wire bundles, an electrical connection is made.
  • Provides redundant current paths, 14-70 (points of contact) per mated contact with a gas-tight junction
  • Very smooth (low friction) interface

Conventional Pin and Socket

  • Machined surface finish on both parts
  • Higher friction and wear
  • Limited number of contact sites
