305-034-556-207

Edgeboard Connectors Overview

The EDAC Inc. 305-034-556-207 is a standard card edge connector designed for dual-edge board applications. It features 34 positions arranged in a dual-row configuration with a 3.96 mm (0.156 inch) pitch. The connector utilizes female contacts made of copper alloy with gold plating, ensuring reliable signal transmission. It supports PCB thicknesses ranging from 1.37 mm to 1.78 mm and operates within a temperature range of -40°C to +105°C. The unit employs a solder pin termination style and includes a green thermoplastic insulator.

• Embedded computing hardware interfaces

Edgeboard Connectors Procurement Notes

Verify the specific suffix codes against the official EDAC datasheet to confirm exact flange and mounting characteristics. Ensure the target PCB thickness falls within the specified 1.37 mm to 1.78 mm range. Confirm that the dual-edge card design matches the mating component requirements before finalizing procurement orders.

Edgeboard Connectors Selection Notes

Select this component when a robust, high-current capable connection is required for thick double-sided circuit boards. The 3.96 mm pitch accommodates larger traces compared to standard connectors. Consider the panel mount orientation and solder termination method during mechanical layout planning to ensure proper alignment and stress distribution.

Edgeboard Connectors Part Context

This part belongs to the EDAC 305 series, which specializes in heavy-duty card edge connectors. The series offers various position counts and mounting options tailored for industrial environments. The 305 series is distinct from lighter-duty alternatives by its focus on durability and higher current ratings suitable for demanding applications.

Edgeboard Connectors Replacement Considerations

Direct substitutes within the same series include parts with identical pitch and row count but different position numbers or flange styles. Verify compatibility with mating cards before swapping. Cross-series replacements require careful evaluation of mechanical dimensions and electrical ratings.
