It belongs to the AMP-Latch series, the workhorse IDC family for parallel cable-to-board interconnects in telecom, datacom, and industrial control panels. ## Termination and Keying Details Termination is IDC — the cable is pressed into the fork contacts, displacing the insulation to make gas-tight connections. No stripping or soldering needed, which keeps assembly time low for multi-conductor cables. The housing includes a feed-through design, so ribbon cable can pass through the connector and continue to another point — useful for daisy-chaining signals across multiple boards. A polarizing key prevents the receptacle from being mated in the wrong orientation, a common source of field errors on unkeyed IDC connectors. The free-hanging (in-line) mount means it sits on the cable, not the board; the matching header takes the board-side position.","metaTitle":"TE Connectivity AMP-Latch 1658621-4, 20-Pin IDC Receptacle","metaDescription":"TE Connectivity AMP-Latch 1658621-4 20-position IDC receptacle, 0.100\" pitch, gold-plated contacts, 26-28 AWG ribbon cable.
