305-028-520-201

Edgeboard Connectors Overview

The EDAC Inc. 305-028-520-201 is a standard card edge connector from the 305 series, designed for reliable electrical interconnection in electronic assemblies. This component features a dual-row configuration with 28 positions and a precise pitch of 3.96 mm (0.156 inches). It utilizes gold-plated copper alloy contacts to ensure low contact resistance and durability. The housing is constructed from thermoplastic polyester, providing robust insulation and mechanical stability. Rated for 5 A continuous current, it supports PCB thicknesses between 1.37 mm and 1.78 mm. Operating within a temperature range of -40°C to +105°C, this vertical panel mount connector offers high insulation resistance of 5 GOhms.

Edgeboard Connectors Procurement Notes

Verify the specific ordering suffix against the official EDAC datasheet to confirm exact pin count, plating thickness, and mounting style. Ensure compatibility with target PCB thickness specifications before procurement. Confirm RoHS compliance status through manufacturer documentation. Cross-reference part numbers with authorized distributors to avoid counterfeit components. Validate environmental ratings against operational requirements.

Edgeboard Connectors Selection Notes

Select this connector when a dual-row interface with 3.96 mm pitch is required for high-current applications up to 5 A. Consider the vertical orientation and panel mount style for chassis integration needs. Evaluate the operating temperature range of -40°C to +105°C against environmental conditions. Ensure the target card thickness falls within the specified 1.37 mm to 1.78 mm range for proper contact engagement.

Edgeboard Connectors Part Context

This component belongs to the EDAC 305 series of standard card edge connectors, which are widely used in industrial and commercial electronics.
