■Features
1. Unique contact configuration (Patented) and
board-mounting pattern
Recommended board layout for
differential routing
The adjacent contacts have different angles of engagement
thus increasing the distance between them, in effect
reducing the cross talk within connector and its footprint.
Contact #3 and # 6, affecting the cross talk the most; have
been isolated from other contacts resulting in maximum
NEXT noise suppression.
In addition, the board layout allows easy tracing of the
differential signal lines.

2. Full EMI shielding
The entire connector is covered with a metal shell. Multiple
panel ground contact springs (2 on each side of the mating
opening) and 4 board ground connection solder contacts
placed at each corner of the connector guarantee effective
suppression of noise radiation.
3. Sequential mating
Separate ground springs (Patent pending) make contact with
the mating connector’s ground before the signal contacts,
allowing equalization of any ground differential.

4. Conforms to FCC (Federal Communications
Commission) standards
Meets requirements of FCC Title 47, Part 68, Subpart F.
■Applications
