305-012-521-568

Edgeboard Connectors Overview

The EDAC Inc. 305-012-521-568 is a standard card edge connector from the 305 series, designed for vertical panel mounting. It features a dual-edge female configuration with 12 positions arranged in two rows. The contact spacing is 0.156 inches (3.96 mm), and the row spacing is 0.140 inches (3.56 mm). The connector accepts printed circuit boards with a nominal thickness of 0.062 inches (1.57 mm). Contacts are made of copper alloy with gold plating, rated for 5 A current. The insulator body is green thermoplastic polyester, operating between -40°C and +105°C.

Edgeboard Connectors Feature Summary

• Dual-edge female design accommodates non-specified double-sided PCBs
• Low-profile insulator body facilitates compact panel installations
• Gold-plated copper alloy contacts ensure reliable signal transmission
• Vertical panel mount style provides secure structural attachment

Edgeboard Connectors Applications

• Industrial control system interconnections
• Telecommunications equipment backplanes
• Test and measurement instrument interfaces
• Embedded computing module connections

Edgeboard Connectors Procurement Notes

Verify the specific suffix codes against official EDAC documentation to confirm exact plating thickness and material specifications. Ensure compatibility with target PCB thickness tolerances before procurement. Confirm RoHS compliance status through manufacturer datasheets. Validate that the dual-edge configuration matches the intended board edge geometry. Cross-reference ordering numbers with authorized distributors to avoid counterfeit components.

Edgeboard Connectors Selection Notes

Select this component when a low-profile, vertically mounted connector is required for double-sided edge cards. The 3.96 mm pitch suits applications needing fewer high-density connections. Verify that the 5 A current rating meets circuit requirements. Consider the thermoplastic insulation properties for environmental resistance. Ensure the panel mounting style aligns with chassis design constraints.

Edgeboard Connectors Part Context

This part belongs to the EDAC 305 series of standard card edge connectors. The series offers various position counts and mounting styles. The 305-012 variant specifically provides a 12-position configuration. It is distinct from single-row or different pitch alternatives within the broader EDAC portfolio.

Edgeboard Connectors Replacement Considerations

Direct substitutes include other EDAC 305 series parts with identical 12-position dual-edge specifications. Verify matching pitch, row spacing, and mounting orientation. Alternative manufacturers may offer similar connectors but require dimensional verification.
