305-074-500-508

Edgeboard Connectors Overview

The EDAC Inc. 305-074-500-508 is a standard card edge connector from the 305 series, designed for panel mounting with a vertical orientation. It features 74 positions arranged in a dual-row configuration with a 3.96 mm (0.156 inch) pitch. The contacts are made of copper alloy and gold-plated, supporting a continuous current rating of 5 A. The housing is constructed from green thermoplastic polyester, accommodating board thicknesses between 1.37 mm and 1.78 mm. It utilizes wire hole termination and operates within a temperature range of -40°C to +105°C.
