305-048-521-501

Edgeboard Connectors Overview

The EDAC Inc. 305-048-521-501 is a standard card edge connector designed for dual-edge board applications. It features 48 positions with a 3.96 mm (0.156 inch) pitch. The connector utilizes female contacts made of copper alloy, finished with gold plating to ensure reliable signal transmission. Rated for 5 A current, it supports PCB thicknesses ranging from 1.37 mm to 1.78 mm. The unit employs a solder pin termination type and is constructed with a green thermoplastic polyester insulator. Designed for panel mounting in a vertical orientation, it operates within a temperature range of -40°C to 105°C.
