305-044-520-502

Edgeboard Connectors Overview

The EDAC Inc. 305-044-520-502 is a standard card edge connector from the 305 series, designed for dual-edge board applications. It features 44 positions with a 3.96 mm (0.156 inch) pitch across two rows. The connector utilizes gold-plated copper alloy contacts and a green thermoplastic polyester insulator. It supports a continuous current rating of 5 A and withstands 1800 VACrms. Designed for panel mounting in a vertical orientation, it accepts PCB thicknesses between 1.37 mm and 1.78 mm. The unit employs solder lug termination and includes flange features for secure installation.

Edgeboard Connectors Feature Summary

• Dual-edge female connector design accommodating non-specified dual-edge cards
• Gold-plated copper alloy contacts with half-bead contact type for reliable signal transmission
• Panel mount vertical installation style with flange features including top opening and no-thread configuration
• Thermoplastic polyester insulation providing high dielectric strength and thermal stability

Edgeboard Connectors Applications

• Industrial control systems requiring robust card-to-board interconnects
• Telecommunications equipment utilizing standardized card edge modules
• Test and measurement instrumentation panels
• Computing hardware backplanes and daughterboard connections

Edgeboard Connectors Procurement Notes

Verify the specific ordering suffix to confirm contact plating thickness and insulator color variants, as these attributes may differ across sub-models within the 305 series. Confirm that the target application PCB thickness falls within the specified 1.37 mm to 1.78 mm range to ensure proper mechanical engagement. Check regional distribution availability, as certain distributors may list this item as not currently sold in specific territories. Ensure compliance with RoHS3 and REACH regulations if required by the end-product specifications.

Edgeboard Connectors Selection Notes

Select this component when a dual-edge card interface with a 3.96 mm pitch is required for panel-mounted configurations. The 44-position count suits applications needing moderate I/O density without excessive board space consumption. Consider the 5 A current rating and 1800 VACrms dielectric strength for power and signal integrity requirements. Evaluate the vertical panel mount style against available chassis real estate and cable routing constraints compared to right-angle or surface-mount alternatives.

Edgeboard Connectors Part Context

This part belongs to the EDAC 305 Series, a line of standard card edge connectors known for durability and versatility. The series offers various position counts and mounting styles to accommodate diverse electronic packaging needs. The 305-044-520-502 specifically addresses the need for a mid-range position count with dual-edge compatibility, fitting into the broader ecosystem of EDAC interconnect solutions for industrial and commercial electronics.

Edgeboard Connectors Replacement Considerations

Direct substitutes within the same series include parts with identical pitch and position counts but different mounting or plating options, such as 305-044-520-202. Verify mechanical dimensions and electrical ratings before cross-referencing with other manufacturers' offerings to ensure compatibility with existing PCB footprints and housing designs.
