306-020-520-112

Overview

The EDAC Inc. 306-020-520-112 is a standard card edge connector receptacle featuring 40 positions with a 3.96 mm (0.156 inch) contact spacing. Designed for dual-edge card insertion, it utilizes gold-plated copper alloy contacts to ensure reliable signal transmission. The unit accommodates printed circuit boards with a nominal thickness of 1.57 mm (0.062 inch). Constructed with a thermoplastic insulator body, this vertical panel-mount component provides secure mechanical retention and electrical isolation for high-density interconnection applications.

Feature Summary

• Dual-edge female connector design accepting two-sided PCB traces
• Gold-plated contacts for enhanced conductivity and corrosion resistance
• Vertical panel mount configuration for fixed installation
• Thermoplastic insulator body providing structural stability

Applications

• High-density electronic module interconnections
• Industrial control system backplanes
• Telecommunications equipment interfaces
• Computing hardware expansion slots

Procurement Notes

Verify the specific ordering suffix against the manufacturer's current datasheet to confirm pin count, contact plating, and board thickness compatibility. Ensure the selected variant matches the required panel mounting style and insulation material specifications. Cross-reference the part number with official distributor catalogs to confirm availability status and compliance certifications such as RoHS before finalizing procurement orders.

Selection Notes

Select this connector when a 40-position interface with 3.96 mm pitch is required for dual-edge cards. Confirm that the target PCB thickness aligns with the 1.57 mm specification to ensure proper contact engagement. Evaluate the need for vertical panel mounting versus other orientations. Verify that the gold contact plating meets the environmental durability requirements for the intended operational lifespan.

Part Context

This component belongs to the EDAC 306 series of standard card edge connectors. The series offers various position counts and mounting styles to support diverse electronic assembly needs. The 306 series is characterized by its robust construction and standardized dimensions, facilitating integration into modular systems requiring reliable high-speed data or power transfer between interconnected boards.

Replacement Considerations

Compatible substitutes within the same series include the 306-020-520-102 and 306-020-520-112 variants, which share identical dimensional profiles and contact configurations. Ensure any replacement maintains the 40-position count and 3.96 mm pitch to guarantee mechanical fit and electrical continuity without modifying the host panel or PCB layout.
