305-070-520-502

Edgeboard Connectors Overview

The EDAC Inc. 305-070-520-502 is a standard card edge connector from the 305 series, designed for dual female termination with 70 positions. It features a 0.156-inch (3.96 mm) pitch and supports board thicknesses ranging from 0.054 to 0.070 inches (1.37 to 1.78 mm). The connector utilizes gold-plated copper alloy contacts and a green thermoplastic polyester insulator. Rated for 5 A current, it operates within a temperature range of -40°C to +105°C and offers vertical panel mounting with .128-inch diameter holes.

Edgeboard Connectors Procurement Notes

Verify the specific suffix codes against the official EDAC ordering guide to confirm exact pin count, plating thickness, and mounting style variations. Ensure compatibility with the target PCB card thickness specifications before procurement. Cross-reference the manufacturer part number with authorized distributor catalogs to confirm current availability and RoHS compliance status.

Edgeboard Connectors Selection Notes

Select this component when a high-density dual-row interface is required for rigid board applications. The 3.96 mm pitch accommodates larger signal traces compared to finer pitches. Verify that the panel mounting hole diameter matches the chassis design constraints. Consider the operating temperature range requirements for the specific environmental conditions of the end application.

Edgeboard Connectors Part Context

This part belongs to the EDAC 305 series of standard card edge connectors. The series is characterized by robust construction suitable for repeated insertion cycles.
