305-028-521-504

Edgeboard Connectors Overview

The EDAC Inc. 305-028-521-504 is a standard card edge connector from the 305 series, designed for panel mount installation with vertical orientation. It features a dual female configuration with 28 positions and a contact spacing of 0.156 inches (3.96 mm). The connector utilizes gold-plated copper alloy contacts with a solder pin termination type. It is rated for 5 A current and operates within a temperature range of -40°C to +105°C. The insulator is made of thermoplastic polyester, and it accepts printed circuit boards with a thickness between 0.054 and 0.070 inches.
