Overview
The EDAC Inc. 306-035-521-102 is a standard card edge connector featuring 70 positions with a 3.96 mm (0.156 inch) pitch. Designed for dual female contact interfaces, it utilizes gold-plated copper alloy contacts to ensure reliable signal transmission. The unit supports a nominal PCB thickness of 1.57 mm and operates within a temperature range of -40°C. Rated for 5 A current, the connector employs a thermoplastic insulator body and offers an insulation resistance of 5 Gohms. It is configured for vertical panel mount installation.
Feature Summary
- Dual female contact configuration for secure card edge engagement
- Gold-plated copper alloy contacts for corrosion resistance
- Vertical panel mount design for structural stability
Applications
- Industrial control system interconnects
- Telecommunications hardware modules
- Test and measurement equipment backplanes
Procurement Notes
Verify that the specific suffix 521-102 matches the required contact plating and insulator color specifications. Confirm that the 70-position count aligns with the target PCB layout dimensions. Ensure the 3.96 mm pitch is compatible with existing board traces. Validate panel mount requirements against the mechanical housing constraints before finalizing the order.
Selection Notes
Select this component when a high-density 70-position interface is required for vertical mounting applications. The 3.96 mm pitch accommodates standard thick PCBs at 1.57 mm. Gold plating is essential for environments requiring long-term reliability without oxidation. The thermoplastic housing provides necessary electrical isolation for industrial ratings.
Part Context
This part belongs to the EDAC 306 series, which specializes in standard card edge connectors. The series is characterized by robust construction suitable for demanding environments. The 306-035 base number indicates the specific form factor and position count category within the manufacturer's standardized product line.
Replacement Considerations
Cross-reference the 306-035-520-102 for alternative plating or color options within the same series. Verify mechanical footprint compatibility before substituting with other manufacturers' 70-position dual-edge connectors.
