Overview
The EDAC Inc. 306-028-520-103 is a standard card edge connector designed for panel mounting applications. It features a dual female configuration with 56 positions arranged in a single row. The connector utilizes a 0.156-inch (3.96 mm) pitch and supports a board thickness of 1.57 mm. Rated for 5 A current, it employs gold-plated copper alloy contacts housed in green thermoplastic insulation. The unit offers flush mount and floating bobbin flange features with a 0.116-inch diameter.
Feature Summary
- Dual female contact configuration for secure card edge engagement
- Flush mount design with floating bobbin flange for alignment tolerance
- Gold-plated copper alloy contacts ensuring reliable signal transmission
- Thermoplastic insulation material providing high dielectric strength
Applications
- Panel-mounted electronic interconnect systems
- Industrial control module connections
- Telecommunications equipment backplanes
Procurement Notes
Verify the specific suffix codes against official EDAC documentation to confirm plating thickness and insulator material variations. Ensure compatibility with the target PCB edge thickness and mounting hole specifications before procurement. Cross-reference the manufacturer part number with authorized distributor catalogs to confirm current availability and lead times. Request sample units for mechanical fit verification in final assembly prototypes.
Selection Notes
Select this component when a dual-row female connector with a 0.156-inch pitch is required for panel mounting. Consider the floating bobbin feature if misalignment compensation between the card and connector is necessary. Verify that the operating temperature range meets the environmental requirements of the intended application. Ensure the housing material compatibility with adjacent components and soldering processes.
Part Context
This component belongs to the EDAC 306 series of standard card edge connectors. The series is characterized by robust construction suitable for industrial environments. The 306 series typically offers various position counts and mounting styles to accommodate diverse system integration needs. This specific model represents a mid-range position count option within the series.
Replacement Considerations
Consult official EDAC substitution guides for direct replacements. Verify pin count, pitch, and mounting style compatibility when evaluating alternative sources. Generic equivalents may lack the specific floating bobbin mechanism or flange dimensions.
