The 20021121-00006T4LF: Both rows are fully loaded, so the 6 positions map to 3 signal pairs or a single 6-conductor ribbon — no blank positions to confuse the harness layout.
Gold on the mating face at 10 µinch thickness over a copper alloy base — this is a signal-grade finish rated for repeated mating in controlled environments. The post (solder tail) is tin-plated at 50 µinch, which wets well during reflow and matches standard lead-free solder profiles.
Surface-Mount Assembly and Board Retention
SMT termination with a push-pull fastening type — no locking latch, so the mating half relies on friction fit. The unshrouded design keeps the profile low and gives visual access to the solder joints for inspection.
