Overview
The EDAC Inc. 306-028-520-107 is a standard single-row card edge connector designed for panel mount applications. It features 28 positions with a 3.96 mm (0.156 inch) contact spacing. The unit accepts printed circuit boards with a nominal thickness of 1.57 mm (0.062 inch). Contacts are constructed from copper alloy and feature gold plating, supporting a current rating of 5 A. The insulator body is made of thermoplastic material, providing an insulation resistance of 5 GOhms. The component operates within a temperature range of -40°C to +105°C.
Feature Summary
- Single centerline row configuration with .156 inch contact spacing
- Accepts .062 inch nominal thickness PCBs
- Low profile insulator body construction
Applications
- Panel-mounted electronic interconnections
- Standard card edge interface systems
- Industrial control hardware connections
Procurement Notes
Verify the specific part number against official EDAC documentation to confirm pin count, spacing, and termination style match your design requirements. Ensure that the PCB thickness tolerance aligns with the specified 1.57 mm acceptance criteria. Confirm that the operating environment falls within the stated temperature limits and that the gold-plated contacts meet the necessary conductivity standards for the application.
Selection Notes
Select this component when a single-row connection with 3.96 mm pitch is required for panel mounting. The 28-position capacity suits moderate-density signal routing. Verify compatibility with 0.062-inch thick circuit boards. Consider the vertical orientation and thermoplastic housing for mechanical stability in fixed installations requiring reliable electrical continuity.
Part Context
This connector belongs to the EDAC 306 series, which specializes in standard card edge connectors. The series is characterized by its .156 inch contact spacing and robust construction suitable for general-purpose industrial applications. The 306-028-520-107 variant specifically provides 28 positions, distinguishing it from other series members with different pin counts or spacing configurations.
Replacement Considerations
Cross-reference with other EDAC 306 series parts sharing the same 3.96 mm pitch and 28-position layout. Verify identical panel mount orientation and PCB thickness compatibility before substitution. Ensure any alternative maintains the same gold-plated contact specification and thermal rating.
