305-034-520-503

Edgeboard Connectors Overview

The EDAC Inc. 305-034-520-503 is a dual-edge female card edge connector designed for panel and through-hole mounting. It features 34 positions arranged in two rows of 17, with a contact spacing of 0.156 inches (3.96 mm). The connector utilizes gold-plated copper alloy contacts with a thickness of 10.0 µin (0.25 µm) and accepts printed circuit boards with a nominal thickness of 0.062 inches (1.57 mm). Operating within a temperature range of -40°C to 105°C, it employs a thermoplastic insulator body and offers a low-profile design suitable for vertical installation.
