305-068-521-503

Edgeboard Connectors Overview

The EDAC Inc. 305-068-521-503 is a dual-edge female card edge connector designed for panel and through-hole mounting. It features 68 positions with a 0.156-inch (3.96 mm) contact pitch and two rows of contacts. The connector utilizes gold-plated copper alloy half-bevel terminals to ensure reliable signal transmission. It is compatible with non-specified dual-edge cards having a thickness range of 0.054 to 0.070 inches. The housing is constructed from green thermoplastic polyester, providing durability across an operating temperature range of -40°C to +105°C.
