305-040-520-504

Edgeboard Connectors Overview

The EDAC Inc. 305-040-520-504 is a standard card edge connector from the 305 series, designed for panel mounting with a vertical orientation. It features 40 positions arranged in a dual row configuration with a 3.96 mm (0.156 inch) pitch. The connector utilizes gold-plated copper alloy contacts and solder pin termination. It supports a current rating of 5 A and operates within a temperature range of -40°C to +105°C. The housing is constructed from thermoplastic material, and it accommodates board thicknesses of 1.57 mm.

Edgeboard Connectors Feature Summary

• Dual-edge female contact design for non-specified card types
• Gold-plated copper alloy contacts for reliable signal transmission
• Thermoplastic housing providing structural integrity and insulation
• Vertical panel mount style with solder pin termination

Edgeboard Connectors Applications

• Industrial control systems requiring robust card edge interfaces
• Telecommunications equipment utilizing standardized connector pitches
• Test and measurement devices needing high-reliability interconnects

Edgeboard Connectors Procurement Notes

Verify the specific ordering suffix against the manufacturer's official datasheet to ensure correct contact finish, housing color, and flange specifications. Confirm RoHS compliance status and REACH restrictions prior to procurement. Cross-reference the Mouser or DigiKey part number with the EDAC manufacturer number to avoid substitution errors. Check regional availability as distribution may vary by location.

Edgeboard Connectors Selection Notes

Select this component when a 40-position dual-row interface is required with a 3.96 mm pitch. Ensure the mating card thickness falls within the specified range of 1.37 mm to 1.78 mm. Verify that the application environment does not exceed the maximum operating temperature of +105°C. Consider the vertical panel mount requirement and solder pin termination method during mechanical design integration.

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 variant specifically provides 40 positions. The numbering system indicates series, position count, and specific feature codes defined by EDAC Inc. for industrial-grade interconnect solutions.

Edgeboard Connectors Replacement Considerations

Direct substitutes include other EDAC 305 series parts with identical 40-position and 3.96 mm pitch specifications, such as 305-040-521-502, provided the contact finish and housing material match the original requirements. Verify mechanical dimensions and electrical ratings before cross-referencing.
