These high-density connectors incorporate a higher density contact pattern and lower-mated height than Amphenol’s standard low mating force rectangular connectors. HDB3 rectangular connectors utilize the same durable and reliable B3 brush contact in a tighter .070” X .060” staggered grid pattern. Available as a daughterboard and motherboard connector for both HDB3 and HSB3, as well as in I/O connector and board stacking connector configurations for HDB3.  

Features & Benefits:

  • High Density:
    Up to 160 brush contacts in a tight .070” X .060” staggered grid pattern – allows for a small board footprint.
  • High Speed:
    Data rates up to 6.250 Gb/s via 100 ohm matched impedance differential pairs.
  • Mating Cycles:
    100K mating cycles vs. 2K for competitive connectors.
  • Low insertion/extraction force:
    1.5 ounce typical per contact.
  • Resistant to shock, vibration & fretting corrosion.
  • Low cost for a high level of performance.
