305-030-521-258

Edgeboard Connectors Overview

The EDAC Inc. 305-030-521-258 is a standard card edge connector designed for dual-edge board insertion. It features 30 positions arranged in two rows with a 0.156-inch (3.96mm) contact spacing. The connector utilizes female half-beam contacts with gold plating over nickel to ensure reliable signal transmission. Constructed with a copper alloy contact material and a green thermoplastic insulator, it supports panel mount installation via through-hole solder termination. The unit accommodates card thicknesses ranging from 0.054 to 0.070 inches and operates within a temperature range of -40°C to 105°C.
