305-048-521-268

Edgeboard Connectors Overview

The EDAC Inc. 305-048-521-268 is a standard card edge connector from the 305 series, designed for vertical panel mounting. It features a dual-row configuration with 48 positions and a 3.96 mm (0.156 inch) pitch. The connector utilizes gold-plated copper alloy contacts with a solder pin termination type. It supports board thicknesses of 1.37 mm to 1.78 mm and operates within a temperature range of -40°C to +105°C. Rated for 5 A current, it offers an insulation resistance of 5 GOhms and uses thermoplastic housing.

Edgeboard Connectors Feature Summary

• Dual-edge female contact design accommodates non-specified double-sided circuit boards.
• Vertical panel mount style provides secure structural installation.
• Gold-plated copper alloy contacts ensure reliable signal transmission.
• Thermoplastic insulation material supports high-temperature operation.

Edgeboard Connectors Applications

• Industrial control system interconnections
• Telecommunications equipment backplanes
• Medical device internal circuitry
• Consumer electronics module interfaces

Edgeboard Connectors Procurement Notes

Verify the specific suffix codes against official EDAC documentation to confirm exact plating thickness and flange dimensions. Ensure compatibility with target PCB edge thickness specifications before ordering. Confirm RoHS compliance status through manufacturer datasheets. Validate that the vertical panel mount orientation matches the mechanical enclosure requirements. Cross-reference the 48-position count with circuit design schematics to prevent mismatched interface configurations.

Edgeboard Connectors Selection Notes

Select this component when a robust vertical connection is required for double-sided cards. The 3.96 mm pitch suits applications needing wider spacing between signals. Verify that the 5 A current rating meets the electrical load requirements. Consider the thermoplastic housing durability for the intended environmental conditions. Ensure the panel mount style aligns with the assembly workflow and space constraints.

Edgeboard Connectors Part Context

This part belongs to the EDAC 305 Series, which specializes in standard card edge connectors. The series offers various position counts and mounting styles. The 305-048 variant specifically addresses higher density needs with 48 positions. It maintains consistent dimensional standards across the family for interchangeability.

Edgeboard Connectors Replacement Considerations

Direct substitutes include EDAC 305-048-521-202 and 305-048-500-201. Verify identical pitch and row configuration. Check for matching flange and mounting hole dimensions. Confirm equivalent current and temperature ratings. Ensure the replacement maintains the same vertical panel mount orientation.
