TX1/TX2/TX3 SERIES CONNECTORS
1.27mm (.050") Contact Spacing, PCB-to-Cable Connectors
• • • • • • • • • • • • • •
TX 1 to 3 Series connectors are two-piece PCB connectors
with 1.27mm (.050") contact spacing.
They are designed for board-to-cable applications.
Configurations include IDC sockets (TX1 and TX2) for flat ribbon
cable; and pin headers (TX3) with a latching mechanism.
Applications include computers, business machines, industrial
control machinery, telecommunications, audiovisual appliances,
measuring equipment, and applications wherever high density
packaging is required.
