The polarizing key and feed-through feature prevent mis-mating and allow daisy-chaining through the cable, which is common in parallel bus or signal distribution layouts. ## Sizing the Wire and the Tooling This receptacle accepts 26-28 AWG ribbon cable — the IDC slot geometry is sized for those gauges. Heavier or lighter cable will not terminate reliably; the insulation thickness and conductor diameter have to land within the fork's bite range. The standard tool for AMP-Latch mass termination is a hand press or arbor press with the correct die set (TE part number 58073-1 or equivalent), which drives all 50 contacts simultaneously. No solder, no individual crimp — the termination is mechanical and gas-tight when done with the right tool. ## How the 50-Position Receptacle Compares to Other AMP-Latch Options The 1-1658621-0's 50 positions serve a denser cable assembly — the 17-position part is for narrower bus widths.","metaTitle":"TE Connectivity AMP-Latch 1-1658621-0, 50-Pin IDC Receptacle","metaDescription":"TE AMP-Latch 50-position IDC receptacle, 0.100\" pitch, 26-28 AWG ribbon cable, gold contacts.
