305-042-520-258

Edgeboard Connectors Overview

The EDAC Inc. 305-042-520-258 is a standard card edge connector from the 305 series, designed for panel mount applications with a vertical orientation. It features a dual female configuration with 42 positions arranged in two rows of 21. The connector utilizes a 3.96 mm (0.156 inch) pitch and accepts board thicknesses between 1.37 mm and 1.78 mm. Contacts are constructed from copper alloy with gold plating to ensure reliable signal transmission. The housing is made of green thermoplastic polyester, supporting an operating temperature range of -40°C to +105°C.

Edgeboard Connectors Feature Summary

• Dual female contact configuration for non-specified card edge boards
• Gold-plated copper alloy contacts for corrosion resistance
• Thermoplastic polyester insulation material
• Vertical panel mount installation style

Edgeboard Connectors Applications

• Embedded system interconnections
• Industrial automation control panels
• General-purpose circuit board mounting

Edgeboard Connectors Procurement Notes

Verify the specific ordering suffix against the manufacturer's official datasheet to confirm pin count, contact finish, and flange specifications. Ensure compatibility with the target PCB thickness range of 1.37 mm to 1.78 mm. Confirm that the vertical panel mount design aligns with the mechanical enclosure requirements. Cross-reference the RoHS status and material declarations if environmental compliance is mandatory for the end application.

Edgeboard Connectors Selection Notes

Select this component when a robust, high-current capable card edge interface is required for vertical panel integration. The 3.96 mm pitch offers spacing suitable for higher voltage isolation compared to finer pitches. Consider the dual-row layout for increased I/O density within a constrained footprint. Verify that the thermoplastic polyester housing meets the thermal and chemical resistance needs of the operational environment.

Edgeboard Connectors Part Context

This part belongs to the EDAC 305 series of standard card edge connectors, which are engineered for durability and consistent performance in demanding environments. The series provides various position counts and mounting options to accommodate diverse electronic assembly needs. Components in this line typically feature semi-crimp contacts for secure mating force and long-term reliability.

Edgeboard Connectors Replacement Considerations

Direct substitutes within the same series include parts with identical pitch and row configurations but different position counts, such as 305-042-520-202 or 305-042-520-508. Verify that any alternative maintains the 3.96 mm pitch and dual female contact type to ensure mechanical and electrical compatibility.
