Introduction
Product Overview
A range of 1.27mm (0.05) pitch connectors, designed for board-to-board and cable-to-board connections. These connectors feature shrouded male and female configurations, with socket connectors utilizing twin-beam female contacts that mate to solid pin male connectors. All board mount connectors are double row, Surface Mount, and supplied in tape-and-reel packaging with pick-and-place caps. They include location pegs for PCB placement assistance and SMT side tabs for enhanced peel strength and strain relief. Available in Vertical and Horizontal orientations, Vertical connectors offer three height options, enabling parallel board-to-board (mezzanine), right-angle motherboard-to-daughterboard, and co-planar/edge-to-edge layouts. All housings incorporate polarization. IDC female connectors are double row, available individually or horizontally mounted to PVC ribbon cable. Housings feature a latch for secure mating.
