305-028-555-258

Edgeboard Connectors Overview

The EDAC Inc. 305-028-555-258 is a standard card edge connector from the 305 series, designed for dual-edge board applications. It features 28 positions with a 3.96 mm (0.156 inch) pitch and supports two rows of contacts. The connector utilizes gold-plated copper alloy terminals and a green thermoplastic insulator. Rated for 5 A current, it accommodates PCB thicknesses between 1.37 mm and 1.78 mm. Operating temperatures range from -40°C to +105°C, with an insulation resistance of 5 GOhms.

Edgeboard Connectors Feature Summary

• Dual-row female configuration for non-specified dual-edge cards
• Gold-plated copper alloy contacts ensure reliable conductivity
• Thermoplastic housing provides structural stability and insulation

Edgeboard Connectors Applications

• Industrial control system interconnects
• Telecommunications equipment backplanes
• Computing hardware module connections

Edgeboard Connectors Procurement Notes

Verify part authenticity through authorized EDAC distributors or certified suppliers. Confirm RoHS3 compliance status prior to procurement. Ensure compatibility with existing panel mounting requirements and verify that the specified 3.96 mm pitch matches the target PCB design constraints before finalizing orders.

Edgeboard Connectors Selection Notes

Select this component when a dual-edge card interface with 28 positions is required. The 3.96 mm pitch and vertical panel mount style suit applications needing robust mechanical retention. Verify that the target PCB thickness falls within the 1.37 mm to 1.78 mm operational window to ensure proper contact engagement and electrical performance.

Edgeboard Connectors Part Context

This connector belongs to the EDAC 305 Series, which offers various position counts and mounting styles. The series is characterized by high-density capabilities and durable construction suitable for demanding environments. The specific model integrates standard solder pin termination methods for secure board attachment.

Edgeboard Connectors Replacement Considerations

Cross-reference with other EDAC 305 series variants having identical 28-position counts and 3.96 mm pitch. Verify that alternative models maintain the same dual-row female configuration and compatible PCB thickness specifications to ensure mechanical and electrical interchangeability.
