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. GENERAL SPECIFICATIONS FEATURES ■ IDC Socket (TX1/TX2) • Flat ribbon cable centers: 0.635mm (.025") for TX1 1.27mm (.050") for TX2 • TX1 socket can be terminated in “daisy-chain” style in the middle of the cable • TX2 socket is terminated at the end of the two stacked cables • Socket contacts have dual-contact-point tuning fork design • All wires can be terminated in a single action (Insulation is automatically removed) ■ Pin Header With Latch (TX3) • Available in straight and right angle through hole types • Self-locking, self-ejecting lever for easy operation Connector Profile (Ref.)
