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.

MIL-DTL-55302 Low Mating Force Connectors
Utilizes the B³ brush contact system known for low mating force, stable electrical performance in high vibration, and extended service life.
The 1.27mm pitch connector. Smaller, lighter & still as strong.
