High reliability Harwin M55-8208042 connectors with twin beam female contacts and gold finish plating
Product Overview
The Harwin Archer Kontrol M55 Series is a range of 1.27mm pitch connectors designed for versatile board-to-board and cable-to-board applications. Featuring twin-beam female contacts that mate to solid pin male connectors, these double-row connectors are available in both Vertical and Horizontal orientations. Surface mount connectors are supplied in tape-and-reel packaging with integrated location pegs and SMT side tabs for enhanced PCB placement and peel strength. Housings include polarization for accurate mating. Latching mechanisms ensure secure connections. The series supports parallel board-to-board (mezzanine), right-angle motherboard-to-daughterboard, and co-planar/edge-to-edge layouts.
