305-040-556-578

Edgeboard Connectors Overview

The EDAC Inc. 305-040-556-578 is a standard card edge connector from the 305 series, designed for dual-edge board applications. It features 40 positions with a 3.96 mm (0.156 inch) pitch and supports a maximum PCB thickness of 1.78 mm. The connector utilizes female half-beam contacts made of copper alloy with gold plating to ensure reliable signal transmission. Rated for 5 A current, it operates within a temperature range of -40°C to +105°C. The housing is constructed from green thermoplastic polyester, providing insulation resistance of 5 GOhms. Mounting is achieved via straddle mount or panel installation methods.
