387-030-521-658

Edgeboard Connectors Overview

The EDAC Inc. 387-030-521-658 is a single-row card edge connector from the 387 Series, designed for through-hole mounting. It features 30 female positions with a 0.156-inch (3.96 mm) contact spacing. The connector utilizes cantilever spring contacts made of copper alloy, finished with 10.0 µin (0.25 µm) gold plating. It accommodates PCB thicknesses ranging from 0.054 to 0.070 inches (1.37 mm to 1.78 mm). The housing is constructed from black thermoplastic polyester, and it includes flanges with top mount openings and 4-40 threaded inserts for secure installation.
