305-038-556-207

Edgeboard Connectors Overview

The EDAC Inc. 305-038-556-207 is a standard card edge connector designed for panel mount applications with a vertical orientation. It features 38 positions in a dual-edge female configuration, utilizing a 3.96 mm (0.156 inch) pitch. The contacts are constructed from copper alloy and finished with gold plating to ensure reliable signal transmission. Rated for 5 A current, the connector accommodates board thicknesses between 1.37 mm and 1.78 mm. It employs a solder pin termination method and operates within a temperature range of -40°C to 105°C.

Edgeboard Connectors Feature Summary

• Dual-edge female contact configuration for secure card insertion
• Gold-plated copper alloy contacts for corrosion resistance
• Panel mount vertical installation style with flange features

Edgeboard Connectors Applications

• Industrial control system interface modules
• Telecommunications equipment backplanes
• Test and measurement instrument cards

Edgeboard Connectors Procurement Notes

Verify that the specific part number matches the required 38-position count and 3.96 mm pitch before procurement. Confirm that the application environment falls within the specified -40°C to 105°C operating temperature range. Ensure the mating card thickness adheres to the 1.37 mm to 1.78 mm specification to guarantee proper mechanical engagement and electrical continuity.

Edgeboard Connectors Selection Notes

Select this component when a high-current 5 A rating and robust gold-plated contacts are required for industrial environments. The vertical panel mount design suits applications needing direct board-to-panel connectivity. Consider the 3.96 mm pitch if wider spacing is necessary compared to standard 2.54 mm connectors. Verify compatibility with existing PCB layouts and mounting hardware requirements.

Edgeboard Connectors Part Context

This component belongs to the EDAC 305 series of edgeboard connectors, which are engineered for demanding industrial and commercial applications. The series offers various position counts and pitch options to accommodate different system architectures. The 305-038-556-207 specifically addresses needs for dual-edge connections with substantial current handling capabilities.

Edgeboard Connectors Replacement Considerations

Direct substitutes may include other EDAC 305 series variants with identical 38 positions and 3.96 mm pitch. Cross-reference mechanical dimensions and flange features to ensure physical compatibility. Verify that alternative components meet the same 5 A current rating and gold plating specifications.
