TX20 SERIES CONNECTORS
1.27mm (.050") Contact Spacing, EMI Shielded, PCB-to-PCB Connectors
The TX20 Series is specifically designed to meet high density
board-to-board interconnection requirements.
TX20 Series connectors enable either a horizontal or vertical
connection between units without using a cable. This low profile
half pitch 1.27mm (.050") connector is designed with an extremely
low mounting height of 5.4mm (.212") for 10 to 120 contacts in
horizontal connection.
The connector features a rugged metal shell that interfaces with
the unit, and the reliable ribbon style contact design protects
against twisting. The metal ground lug provides excellent EMI
shielding for applications that require EMI protection as well as
high density.
The flexibility of this connector makes it an ideal product for
notebook computers and other high density applications such as
disk drives and memory devices.

FEATURES
Contact spacing on mating side:
1.27mm (.050") double row (10 to 120 contacts)
1.27mm (.050") 4 rows (200 contacts)
Contact spacing on tail side:
1.27mm (.050") between contacts
1.905mm (.075") between staggered rows
Horizontal or vertical connection between
boards is accomplished by combining right
angle receptacles with straight or right
angle plugs
Reliable ribbon style contacts are more durable
against twisting during mating or unmating
Ground lug is provided on tail for grounding
to PCB
Eight longer contacts on the outer ends of the
receptacle are extended for first to make, last
to break
Note 1: Straight plug is available only with 120 contacts.
