306-024-500-103

Overview

The EDAC Inc. 306-024-500-103 is a dual female card edge connector designed for panel mount applications. It features 56 positions arranged in two rows with a contact spacing of 0.156 inches (3.96 mm). The connector utilizes copper alloy cantilever contacts with a gold plating thickness of 10.0 µin (0.25 µm) to ensure reliable signal transmission. It supports non-specified double-sided cards with a thickness range of 0.054 to 0.070 inches (1.37 mm to 1.78 mm). The housing is constructed from green thermoplastic polyester, and the unit operates within a temperature range of -40°C to 105°C.

Feature Summary

• Dual row configuration providing 56 total connection points
• Cantilever contact design for secure board retention
• Gold-plated copper alloy terminals for corrosion resistance
• Panel mount installation with flush flange characteristics

Applications

• Industrial control system interconnects
• Telecommunications equipment backplanes
• Test and measurement instrument interfaces
• General-purpose electronic module connections

Procurement Notes

Verify that the specific part number matches the required pin count and pitch specifications before ordering. Confirm compatibility with the target printed circuit board thickness limits. Ensure that the mounting hole dimensions align with the connector's flange design. Check for RoHS compliance requirements if applicable to the final assembly. Review lead times as this item may be supplied on order rather than from immediate stock.

Selection Notes

Select this component when a high-density connection with 0.156-inch spacing is required for double-sided boards. Consider the thermal stability provided by the thermoplastic polyester insulation for environments up to 105°C. Evaluate the mechanical robustness of the cantilever contacts against vibration requirements. Compare alternative series if different termination methods or flange styles are necessary for the enclosure design.

Part Context

This connector belongs to the EDAC 306 Series, which specializes in standard card edge connectors with 0.156-inch spacing. The series offers various configurations including single and double rows with multiple termination options. The 306-024 variant specifically denotes a 56-position dual row layout. This family is widely used in modular electronics where reliable, repeatable mating cycles are essential for system maintenance and expansion.

Replacement Considerations

Direct substitutes include other EDAC 306 series parts with identical 56-position dual row layouts and 0.156-inch pitch. Verify that any replacement maintains the same contact plating thickness and material composition. Ensure that the insulator material and operating temperature range match the original design constraints. Cross-reference flange dimensions to guarantee proper panel fitment.
