Overview
The EDAC Inc. 306-026-421-102 is a standard card edge connector receptacle designed for panel mount applications. It features a dual-edge configuration with 52 positions and a contact spacing of 3.96 mm (0.156 inches). The unit utilizes tin-plated copper alloy contacts and a green thermoplastic polyester insulator body. It accepts printed circuit boards with a nominal thickness of 1.57 mm (0.062 inches) and employs a solder pin termination style.
Feature Summary
- Dual-edge female connector design accommodating specified board thicknesses
- Low profile insulator body constructed from thermoplastic polyester
- Panel mount installation with vertical orientation
Applications
- Electronic module interconnection
- Industrial control system backplanes
- Telecommunications equipment interfaces
Procurement Notes
Verify the specific ordering suffix to confirm contact plating and insulation color, as variations exist within the series. Confirm that the target application requires a dual-edge receptacle rather than a single-edge variant. Ensure the PCB thickness aligns with the 1.57 mm specification before procurement. Cross-reference the manufacturer part number against official distributor catalogs to avoid confusion with similar series components.
Selection Notes
Select this component when a high-density connection is required for double-sided edge cards. The 3.96 mm pitch offers a balance between signal density and mechanical robustness. Consider the tin plating for general-purpose environments where gold plating is not strictly necessary. Verify that the panel mount footprint matches the available chassis space in the final assembly design.
Part Context
This component belongs to the EDAC 306 Series, which focuses on standard density card edge connectors. The series provides various position counts and mounting styles to support diverse electronic enclosure requirements. The 306-026-421-102 represents a specific configuration optimized for dual-edge applications within this standardized product line.
Replacement Considerations
Compatible substitutes include other EDAC 306 series receptacles with matching 52-position counts and 3.96 mm pitch. Verify that alternative parts maintain the same dual-edge geometry and panel mount dimensions to ensure mechanical interchangeability without redesigning the host enclosure.
