305-040-500-578

Edgeboard Connectors Overview

The EDAC Inc. 305-040-500-578 is a standard card edge connector from the 305 series, designed for panel mounting applications. It features a dual-edge configuration with 40 positions arranged in two rows. The contact pitch is 0.156 inches (3.96 mm), and it accommodates printed circuit boards with a nominal thickness of 0.062 inches (1.57 mm). The contacts are made of copper alloy with gold plating to ensure reliable signal transmission. Rated for 5 A current, the connector utilizes a solder lug termination type for secure board attachment. The insulator body is constructed from thermoplastic material, providing stability across an operating temperature range of -40°C to +105°C.
