305-078-556-202

Edgeboard Connectors Overview

The EDAC Inc. 305-078-556-202 is a dual-edge female card edge connector designed for board-to-board or backplane interconnections. It features 78 positions with a 0.156-inch (3.96 mm) contact spacing and accepts PCB thicknesses ranging from 0.054 to 0.070 inches. The connector utilizes gold-plated copper alloy contacts with a 10.0 µin plating thickness, housed in a green thermoplastic polyester insulator. Rated for 5 A current, it supports solder pin termination and operates within a temperature range of -40°C to +105°C.
