746-084-520-201

Edgeboard Connectors Overview

The EDAC Inc. 746-084-520-201 is a dual female card edge connector designed for vertical board-to-board interconnection. It features 84 positions with a 0.125-inch (3.18mm) pitch, accommodating card thicknesses between 0.054 and 0.070 inches. The contacts are gold-plated copper alloy with a 30.0µin thickness, utilizing a cantilever spring design for reliable engagement. Rated for operation from -40°C to 105°C, it employs a thermoplastic polyester insulator and supports through-hole termination via crimp or wire wrap methods.
