306-024-521-107

Overview

The EDAC Inc. 306-024-521-107 is a standard card edge connector featuring 56 positions with a 3.96 mm (0.156 inch) pitch. It utilizes a dual female contact configuration and gold plating on copper alloy terminals. Designed for panel mounting, this vertical header supports PCB thicknesses between 1.37 mm and 1.78 mm. The insulator body is constructed from green thermoplastic polyester, rated for operation between -40°C and +105°C.

Feature Summary

• Dual-edge female contact design for non-specified card edge applications
• Gold-plated copper alloy contacts ensure reliable signal transmission
• Vertical panel mount orientation with integrated flange features

Applications

• Industrial control system interconnects
• Telecommunications equipment backplanes
• Test and measurement instrument modules

Procurement Notes

Verify the specific pin count and row configuration against the target PCB layout to ensure mechanical compatibility. Confirm that the mating card edge thickness falls within the specified range of 1.37 mm to 1.78 mm. Check RoHS compliance status if environmental regulations apply to the final assembly. Ensure the vertical mounting style aligns with the enclosure design constraints.

Selection Notes

Select this component when a high-density connection is required for double-sided edge cards. The 3.96 mm pitch offers robust spacing for industrial environments. Consider the dual-row architecture if space efficiency is critical compared to single-row alternatives. Verify that the gold plating meets the conductivity requirements for the intended signal frequencies.

Part Context

This part belongs to the EDAC 306 series, which specializes in standard card edge connectors. The series provides various position counts and termination options for diverse electronic assemblies. The 306-024 variant specifically addresses higher density needs within the family, offering 56 positions while maintaining the standard 0.156-inch pitch characteristic of the line.

Replacement Considerations

Direct substitutes within the same series include parts with identical pitch and row configurations but different pin counts, such as 306-025-521-107 or 306-021-521-107. Cross-series replacements require careful verification of mechanical dimensions and electrical ratings to ensure functional equivalence.
