Gold finish contact connectors Harwin M55-8202042 with phosphor bronze material and nickel plating
Product Overview
A range of 1.27mm (0.05) pitch connectors, including male and female shrouded connectors designed for board-to-board and cable-to-board connections. The M55 Series features twin-beam female contacts that mate to solid pin male connectors. Board mount connectors are double row, Surface Mount, and supplied in tape-and-reel packaging. All housings incorporate location pegs for PCB placement assistance and SMT side tabs for enhanced peel strength and strain relief. Available in Vertical or Horizontal orientations with multiple height options for vertical connectors, this range supports parallel board-to-board (mezzanine), right-angle motherboard-to-daughterboard, and co-planar/edge-to-edge layouts. Polarization is integrated into all housings. IDC female connectors are double row, available individually or horizontally mounted to a PVC ribbon cable. Connector housings feature a latch for secure mating.
