305-044-555-558

Edgeboard Connectors Overview

The EDAC Inc. 305-044-555-558 is a standard card edge connector from the 305 series, designed for vertical panel mounting. It features 44 positions with a 3.96 mm (0.156 inch) contact spacing and supports two rows of contacts. The connector accepts printed circuit boards with a nominal thickness of 1.57 mm (0.062 inch). Contacts are made of copper alloy with gold plating to ensure reliable signal transmission. Rated for 5 A current, it utilizes a solder lug termination method for secure board attachment.
