Overview
The EDAC Inc. 306-028-500-107 is a standard card edge connector from the 306 series, designed for panel mounting applications. It features a dual female configuration with 56 positions arranged in two rows. The connector utilizes a 0.156-inch (3.96 mm) contact spacing and accepts printed circuit boards with a nominal thickness of 0.062 inches (1.57 mm). The contacts are constructed from copper alloy with gold plating to ensure reliable electrical performance.
Feature Summary
- Dual female contact configuration providing 56 total positions across two rows
- Gold-plated copper alloy contacts for enhanced conductivity and durability
- Low profile insulator body designed for space-constrained panel installations
Applications
- Industrial control systems requiring robust board-to-board connections
- Automotive electronics assemblies needing secure panel-mounted interfaces
- Communication equipment utilizing standardized card edge form factors
Procurement Notes
Verify that the specific part number matches the required 56-position dual row specification. Confirm compatibility with the target PCB thickness of 0.062 inches. Ensure the gold-plated contact finish meets the application's environmental requirements. Check for any regional distribution restrictions or availability constraints before finalizing procurement plans.
Selection Notes
Select this component when a dual-sided card edge interface is required for panel mounting. The 0.156-inch pitch accommodates standard board layouts within the 306 series ecosystem. Consider the low-profile design if vertical clearance is limited. Verify that the gold plating on the copper alloy contacts satisfies the necessary cycle life and corrosion resistance standards for the intended operational environment.
Part Context
This component belongs to the EDAC 306 series, which specializes in .156-inch pitch card edge connectors. The series offers various position counts and termination styles to support diverse electronic assembly needs. The 306-028-500-107 specifically addresses applications requiring a high-density dual-row interface with reliable solder eyelet termination for secure mechanical attachment.
Replacement Considerations
Compatible substitutes within the same series include the 306-009-500-104 and 306-033-521-107. These alternatives share the same fundamental .156-inch pitch and series characteristics but differ in position count and specific termination details. Cross-reference the exact pin configuration and board thickness tolerance before substituting.
