305-040-520-503

Edgeboard Connectors Overview

The EDAC Inc. 305-040-520-503 is a standard card edge connector header from the 305 series, designed for vertical panel mounting. It features 40 positions with a 3.96 mm (0.156 inch) pitch and supports dual-edge card insertion. The contacts are made of copper alloy with gold plating, rated for 5 A continuous current. The housing is green thermoplastic, accommodating board thicknesses of 1.57 mm. It operates within a temperature range of -40°C to +105°C and provides an insulation resistance of 5 GOhms.

Edgeboard Connectors Feature Summary

• Dual-edge female contact configuration for secure card engagement
• Vertical panel mount style with solder pin termination
• Gold-plated copper alloy contacts ensuring reliable conductivity
• Thermoplastic housing compatible with polarizing keys

Edgeboard Connectors Applications

• Industrial control system interface connections
• Telecommunications equipment backplane integration
• Test and measurement instrument module docking
• Automotive electronics board interconnects

Edgeboard Connectors Procurement Notes

Verify the specific suffix code against official EDAC documentation to confirm exact housing color and contact finish specifications. Ensure compatibility with the target PCB card thickness of 1.57 mm before procurement. Confirm that the vertical panel mount orientation aligns with the mechanical design requirements of the enclosure. Check for RoHS compliance status in the latest datasheet revision prior to ordering.

Edgeboard Connectors Selection Notes

Select this component when a 40-position dual-edge connection is required with a 3.96 mm pitch. The 5 A current rating suits moderate power signal applications. Verify that the operating environment stays within the -40°C to +105°C range. Consider the vertical panel mount constraint for spatial planning. Ensure the mating card utilizes compatible polarizing key slots if present.

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 305-040-520-503 specifically denotes the 40-position variant with dual-edge contacts and green thermoplastic housing. It is distinct from single-edge or different pitch variants within the same family.

Edgeboard Connectors Replacement Considerations

Direct substitutes include other EDAC 305 series parts with identical 40-position dual-edge configurations and 3.96 mm pitch, such as 305-040-520-203 or 305-040-520-268, provided housing color differences are acceptable. Cross-manufacturer replacements require matching pitch, position count, and current ratings.
