305-038-556-502

Edgeboard Connectors Overview

The EDAC Inc. 305-038-556-502 is a dual-edge female card edge connector designed for board-to-board interconnection. It features 38 positions with a 0.156-inch (3.96mm) pitch across two rows. The contacts are constructed from copper alloy with a gold plating thickness of 10.0µin (0.25µm). Designed for panel mount installation, it accommodates card thicknesses between 0.054 and 0.070 inches. The housing is made of green thermoplastic polyester, ensuring reliable performance within an operating temperature range of -40°C to +105°C.

Edgeboard Connectors Feature Summary

• Dual-edge female configuration provides robust electrical connectivity for non-specified double-sided cards.
• Gold-plated half-wave spring contacts ensure low contact resistance and durable mating cycles.
• Panel-mount design with flange features allows for secure cross-rider installation on chassis panels.

Edgeboard Connectors Applications

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

Edgeboard Connectors Procurement Notes

Verify the specific suffix codes against the manufacturer's current ordering guide to confirm plating thickness and material specifications. Ensure that the target PCB or card edge dimensions strictly adhere to the specified tolerance ranges for proper mechanical fit. Confirm RoHS3 compliance requirements match the project's environmental standards before finalizing the procurement order.

Edgeboard Connectors Selection Notes

Select this component when a high-density connection with a 3.96mm pitch is required for panel-mounted applications. Consider the 38-position count and dual-row layout for space-constrained designs. Evaluate the thermal stability of the thermoplastic insulation against the operational environment temperatures to ensure long-term reliability under stress conditions.

Edgeboard Connectors Part Context

This part belongs to the EDAC 305 Series, a line of standard card edge connectors known for their versatility in industrial and commercial electronics. The series offers various position counts and mounting styles, providing engineers with standardized solutions for reliable signal and power transmission in modular electronic systems.

Edgeboard Connectors Replacement Considerations

Direct substitutes within the same series include 305-038-556-508, which shares identical mechanical dimensions and pin count but may differ in environmental compliance or specific plating variations. Always verify cross-reference compatibility through official manufacturer documentation before implementation.
