305-040-521-507

Edgeboard Connectors Overview

The EDAC Inc. 305-040-521-507 is a standard card edge connector from the 305 series, designed for panel mount installation with a vertical orientation. It features a dual female configuration with 40 positions arranged in two rows. The connector utilizes a 3.96 mm (0.156 inch) contact spacing and accepts printed circuit boards with a nominal thickness of 1.57 mm (0.062 inch). Contacts are made of copper alloy with gold plating to ensure reliable signal transmission. The unit employs a solder pin termination type for secure board attachment.

Edgeboard Connectors Feature Summary

• Dual-row female connector design accommodating non-specified dual-edge cards
• Gold-plated copper alloy contacts for enhanced conductivity and corrosion resistance
• Vertical panel mount style with solder pin termination for stable integration
• Low-profile insulator body constructed from thermoplastic polyester

Edgeboard Connectors Applications

• Industrial control systems requiring robust interconnects
• Telecommunications equipment backplanes
• Test and measurement instrumentation interfaces
• Automotive electronics modules

Edgeboard Connectors Procurement Notes

Verify that the specific ordering suffix matches the required contact spacing and board thickness specifications. Confirm RoHS compliance status and environmental ratings such as operating temperature range before finalizing procurement orders. Ensure compatibility with existing panel mounting hardware and PCB design constraints.

Edgeboard Connectors Selection Notes

Select this component when a high-current capacity connection is needed for thick PCBs. The 3.96 mm pitch offers reduced density compared to finer pitches but provides greater mechanical stability. Consider the vertical mounting profile for space-constrained panel applications where direct board insertion is preferred over horizontal stacking.

Edgeboard Connectors Part Context

This part belongs to the EDAC 305 Series, which specializes in heavy-duty card edge connectors. The series is characterized by its ability to handle significant mechanical stress and electrical loads. Variations within the series differ primarily in position count, row configuration, and mounting style options to suit diverse industrial connectivity requirements.

Edgeboard Connectors Replacement Considerations

Direct substitutes include EDAC part numbers 305-040-520-507 and 305-040-521-208, which share similar form factors and electrical characteristics. Verify exact dimensional tolerances and insulation material properties when cross-referencing alternative suppliers or updated product revisions.
