305-054-520-502

Edgeboard Connectors Overview

The EDAC Inc. 305-054-520-502 is a standard card edge connector from the 305 series, designed for panel mount applications with a vertical orientation. It features a dual female configuration with 54 positions and a 3.96 mm (0.156 inch) pitch. The connector utilizes gold-plated copper alloy contacts with a half-bead type termination style for solder lug attachment. It supports non-specified dual-edge cards within a thickness range of 1.37 mm to 1.78 mm. The housing is constructed from green thermoplastic polyester, ensuring compliance with RoHS3 standards.

Edgeboard Connectors Feature Summary

• Dual female contact configuration for reliable signal transmission
• Gold-plated copper alloy terminals for corrosion resistance
• Thermoplastic polyester insulation for thermal stability
• Panel mount vertical installation design

Edgeboard Connectors Applications

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

Edgeboard Connectors Procurement Notes

Verify the specific ordering suffix against the official EDAC 305 Series Ordering Guide to ensure correct pin count and termination style. Confirm that the target PCB or card edge thickness falls within the specified 1.37 mm to 1.78 mm range. Check for RoHS3 compliance requirements if operating in restricted substance environments. Ensure panel mounting holes align with the flange specifications provided in the mechanical drawing.

Edgeboard Connectors Selection Notes

Select this component when a high-density, dual-edge card interface is required for panel-mounted assemblies. The 3.96 mm pitch offers a balance between signal density and spacing reliability. Consider the vertical orientation for space-constrained enclosures where board-to-board height is limited. Verify that the 5 A current rating meets the application's electrical load requirements without exceeding thermal limits.

Edgeboard Connectors Part Context

This part belongs to the EDAC 305 Series of standard card edge connectors, which are widely used in industrial and commercial applications. The series offers various position counts and termination options to accommodate different system architectures. The 305-054 variant specifically addresses needs for moderate-to-high density connections with durable metal contacts and stable polymer insulation.

Edgeboard Connectors Replacement Considerations

Direct substitutes may include other EDAC 305 series parts with matching 54-position counts and 3.96 mm pitch, such as 305-050-556-502 or 305-050-520-502, provided the termination style and card thickness compatibility are verified. Cross-referencing mechanical dimensions and electrical ratings is essential before substitution.
