305-042-555-202

Edgeboard Connectors Overview

The EDAC Inc. 305-042-555-202 is a standard card edge connector from the 305 series, designed for dual-edge board applications. It features 42 positions with a 0.156-inch (3.96 mm) pitch and supports two rows of contacts. The connector utilizes female half-beam contact types made of copper alloy with gold plating. It is rated for 5 A current and operates within a temperature range of -40°C to +105°C. The housing is green thermoplastic polyester, suitable for panel mount installation at a vertical angle.
