Overview
The EDAC Inc. 306-039-520-101 is a standard card edge connector featuring 78 positions with a 0.156 inch (3.96 mm) pitch. It utilizes a dual female contact configuration and gold plating for reliable signal transmission. The unit supports a current rating of 5 A and includes an insulation resistance specification of 5 Gohms. Designed for panel mounting in a vertical orientation, the housing is constructed from thermoplastic material, while contacts are made from copper alloy.
Feature Summary
- Dual edge female contact design for secure board interface
- Gold-plated copper alloy contacts ensure corrosion resistance
- Thermoplastic housing provides structural stability
Applications
- Panel-mounted electronic assemblies requiring high-density connections
- Industrial control systems utilizing card edge interfaces
- Vertical interconnect applications in modular hardware designs
Procurement Notes
Verify the specific ordering suffix to confirm pin count, contact plating thickness, and housing color variations. Ensure compatibility with the target PCB card thickness and panel cutout dimensions before procurement. Confirm that the 5 A current rating aligns with the system's electrical requirements. Cross-reference the datasheet for precise mechanical drawings to validate mounting hole patterns and overall envelope dimensions.
Selection Notes
Select this component when a 78-position dual-edge interface is required for vertical panel mounting. The 3.96 mm pitch accommodates specific board trace spacing needs. Verify that the thermoplastic housing material meets environmental standards for the intended operating temperature range. Ensure the gold contact plating satisfies long-term reliability requirements for the application environment.
