387-039-524-658

Edgeboard Connectors Overview

The EDAC Inc. 387-039-524-658 is a single-row edgeboard connector from the 387 Series, designed for vertical through-hole mounting. It features 39 positions with a 0.156-inch (3.96mm) contact spacing and accepts non-specified single-edge cards within a thickness range of 0.054 to 0.070 inches. The connector utilizes copper alloy cantilever contacts with gold plating and a thermoplastic polyester insulator. Operating temperature spans -40°C to 105°C, and it includes flange features for secure panel installation.

Edgeboard Connectors Feature Summary

• Cantilever contact design ensures reliable mating with single-edge circuit boards
• Gold-plated terminals provide corrosion resistance and stable signal transmission
• Thermoplastic polyester insulation supports high-temperature industrial environments
• Vertical through-hole termination facilitates standard PCB assembly processes

Edgeboard Connectors Applications

• Industrial control system backplanes
• Telecommunications equipment interconnects
• Medical device internal module connections
• Energy management system interface boards

Edgeboard Connectors Procurement Notes

Verify that the specific ordering suffix matches the required flange configuration and contact length. Confirm compliance with RoHS3 and REACH regulations for the target market. Ensure the selected variant aligns with the mechanical constraints of the host enclosure and the precise card thickness requirements of the application design.

Edgeboard Connectors Selection Notes

Select this component when a single-row, high-pin-count connection is required for vertical board insertion. The 0.156-inch pitch accommodates standard edge card layouts. Consider the thermal rating and material compatibility if operating in harsh environmental conditions or requiring long-term reliability in automated manufacturing settings.

Edgeboard Connectors Part Context

This part belongs to the EDAC 387 Series, which offers various configurations including different row counts, contact lengths, and flange options. The series is engineered for robust performance in demanding applications, providing consistent electrical connectivity across a wide range of industrial and commercial electronic systems requiring durable edgeboard interfaces.

Edgeboard Connectors Replacement Considerations

Direct substitutes include other EDAC 387 Series variants with identical pin counts and spacing but differing flange styles or contact tail lengths. Cross-brand replacements require matching the 0.156-inch pitch, single-row architecture, and through-hole mounting profile to ensure mechanical fit and electrical continuity.
