The housing includes a polarizing key and a feed-through feature, which together prevent mis-mating and allow daisy-chaining through the connector body.
This connector terminates ribbon cable via insulation displacement — the 28-30 AWG conductors are pressed into the fork-shaped contacts, which cut through the insulation and grip the wire without stripping. The dual-row layout gives 20 positions in a compact width, suitable for parallel data or signal buses.
Mating and Polarization
The 71600-120LF mates with a 20-position, 0.100" pitch, dual-row pin header — typically a Quickie™ series header or any standard 0.100" shrouded or unshrouded header with matching position count and row spacing. The polarizing key in the housing aligns with a corresponding slot in the mating header, ensuring the connector cannot be inserted backwards or offset. The feed-through feature allows the cable to pass through the connector body, which is useful for daisy-chain or pass-through wiring in a harness.
