305-058-556-502

Edgeboard Connectors Overview

The EDAC Inc. 305-058-556-502 is a dual-edge female card edge connector designed for board-to-board interconnection. It features 58 positions with a 0.156-inch (3.96mm) pitch across two rows. The connector utilizes gold-plated contacts and a green thermoplastic polyester insulator. It supports PCB thicknesses between 0.054 and 0.070 inches, operates within -40°C to 105°C, and complies with RoHS3 standards.

Edgeboard Connectors Feature Summary

• Dual-edge female configuration for non-specified card types
• Gold-plated semi-crimped contacts for reliable signal transmission
• Thermoplastic polyester insulation with green color coding
• Panel mount installation style with flange features

Edgeboard Connectors Applications

• Industrial control system backplanes
• Telecommunications equipment interfaces
• Test and measurement instrument modules
• Computer peripheral expansion slots

Edgeboard Connectors Procurement Notes

Verify the specific suffix codes against the official EDAC ordering guide to ensure correct contact plating thickness and flange dimensions. Confirm that the target PCB design accommodates the specified 0.156-inch pitch and dual-row layout. Check for RoHS3 compliance requirements if operating in regulated regions. Ensure storage conditions prevent moisture damage prior to soldering.

Edgeboard Connectors Selection Notes

Select this component when a high-density 58-position interface is required on a dual-edge card. The 0.156-inch pitch offers robust mechanical stability compared to finer pitches. Verify that the mating card thickness falls within the 0.054 to 0.070 inch range for proper engagement. Consider the operating temperature range of -40°C to 105°C for environmental suitability.

Edgeboard Connectors Part Context

This part belongs to the EDAC 305 series of standard card edge connectors. The series provides various position counts and mounting options for general-purpose electronic applications. The 305-058 variant specifically addresses needs for moderate-to-high density connections in compact form factors.

Edgeboard Connectors Replacement Considerations

Cross-reference with other EDAC 305-series parts sharing the same 0.156-inch pitch and 58-position count. Verify identical flange diameters and panel mount compatibility before substitution. Ensure mating card specifications match the original design constraints.
