Overview
The EDAC Inc. 306-027-400-103 is a standard card edge connector featuring 54 positions arranged in a dual-row configuration with a 3.96 mm pitch. Designed for vertical panel mounting, it utilizes copper alloy contacts plated with tin and a green thermoplastic housing. The component supports a current rating of 5 A and offers an insulation resistance of 5 GOhms. It operates within a temperature range of -40°C to +105°C and accommodates a board thickness of 1.57 mm.
Feature Summary
- Dual-edge female contact design for secure card insertion
- Vertical panel mount orientation for structural stability
- Thermoplastic insulation providing high dielectric strength
Applications
- Industrial control system backplanes
- Telecommunications equipment interfaces
- Test and measurement instrument modules
Procurement Notes
Verify the specific contact plating variant required for your application environment. Confirm that the 3.96 mm pitch aligns with the mating card edge specifications. Ensure the panel cutout dimensions match the mechanical drawing provided in the official datasheet to guarantee proper fit and alignment during assembly.
Selection Notes
Select this component when a robust, high-current connection is needed for thick PCBs. The dual-row layout maximizes I/O density within a limited footprint. Consider the tin plating for general-purpose use where gold plating is not strictly necessary for corrosion resistance or low-contact resistance requirements.
Part Context
This part belongs to the EDAC 306 series of standard card edge connectors. The series is characterized by its durable construction and compatibility with various industrial standards. The 306 series provides reliable interconnection solutions for applications requiring frequent insertion cycles and stable electrical performance under varying environmental conditions.
Replacement Considerations
Direct substitutes include EDAC part numbers from the same 306 series with matching position counts and pitch specifications. Verify that any alternative maintains the same dual-edge female configuration and vertical mounting style to ensure mechanical compatibility.
