TX20A SERIES CONNECTORS
1.27mm (.050") Contact Spacing, PCB-to-Cable (IDC Type) Connectors
• • • • • • • • • • • • • •
TX20A Series connectors are extremely low profile, high density
connectors with contact spacing on 1.27mm (.050") centers. This
series includes receptacles (board side), plugs (IDC termination)
and hoods with a locking mechanism. This product is ideal for
interface between electronic units. The ribbon type contact
configuration will not fail under a twisting force during mating
and unmating. The rapid locking system provides a positive
“click” feel when locked. The TX20A Series is highly reliable and
has excellent EMI shielding. The connectors provide flexibility in
connecting between units of state-of-the-art electronic devices,
such as laptop and pocket-type miniature computers.
