302-124-656-201

Edgeboard Connectors Overview

The EDAC Inc. 302-124-656-201 is a standard card edge connector from the 302 series, designed for dual-edge board applications. It features 124 positions with a female contact type and a 0.050 inch (1.27mm) pitch. The connector utilizes gold-plated contacts on a copper alloy base, housed in a black polyamide (PA66) insulator. It supports board thicknesses between 0.051 and 0.071 inches (1.30mm to 1.80mm). The component operates within a temperature range of -55°C to 85°C and employs a solder termination method for secure PCB mounting.
