345-074-525-258

Edgeboard Connectors Overview

The EDAC Inc. model 345-074-525-258 is a standard card edge connector from the 345 series, designed for reliable signal transmission in electronic assemblies. It features a dual female configuration with 74 positions arranged in two termination rows. The component utilizes a 2.54 mm (0.100 inch) pitch and supports a board thickness of 1.57 mm. Termination is achieved via wire wrap connections, ensuring secure attachment to printed circuit boards. The contacts are gold-plated copper alloy, providing corrosion resistance and low contact resistance. Rated for 3 A current, it operates within a temperature range of -40°C to +105°C.
