305-044-520-558

Edgeboard Connectors Overview

The EDAC Inc. 305-044-520-558 is a standard card edge connector featuring 44 positions arranged in a dual-row configuration. It utilizes a 3.96 mm (0.156 inch) contact spacing with a 3.56 mm row spacing. Designed for vertical panel mounting, the component accepts printed circuit boards with a nominal thickness of 1.57 mm (0.062 inch). The contacts are constructed from copper alloy and feature gold plating to ensure reliable signal transmission. Rated for 5 A current at temperatures ranging from -40°C to +105°C, it offers an insulation resistance of 5 GOhms.

Edgeboard Connectors Feature Summary

• Dual-edge female contact design accommodates double-sided PCB edges

• Gold-plated copper alloy contacts ensure durable electrical connectivity
• Thermoplastic insulator body supports operation across extended temperature ranges

Edgeboard Connectors Applications

• Industrial control system interface modules
• Telecommunications equipment backplanes
• Automotive electronic control units
• Medical device internal interconnects

Edgeboard Connectors Procurement Notes

Verify the specific ordering suffix against the official EDAC datasheet to confirm exact pin count, termination style, and plating specifications. Ensure compatibility with the target PCB thickness of 1.57 mm and verify that the panel cutout dimensions align with the connector's mechanical envelope. Confirm RoHS compliance status through the manufacturer's latest documentation before finalizing procurement.

Edgeboard Connectors Selection Notes

Select this component when a high-density connection is required within a limited vertical space. The 3.96 mm pitch allows for substantial conductor routing while maintaining a robust mechanical profile. Consider the 5 A current rating and wide operating temperature range for environments subject to thermal cycling. Ensure the application requires a dual-edge connector rather than a single-edge variant.

Edgeboard Connectors Part Context

This part belongs to the EDAC 305 series of standard card edge connectors. The series is characterized by its use of thermoplastic insulators and gold-plated contacts. The 305 series provides various position counts to suit different board densities while maintaining consistent mechanical and electrical performance standards across the product line.
