387-028-556-812

Edgeboard Connectors Overview

The EDAC Inc. 387-028-556-812 is a dual-edge card edge connector from the 387 Series, designed for vertical through-hole mounting. It features 28 positions with a 0.156-inch (3.96 mm) pitch and accepts board thicknesses of 1.57 mm. The contacts are made of copper alloy with gold plating, ensuring reliable signal transmission. The housing is constructed from thermoplastic polyester in black, rated for operation between -40°C and +105°C.

Edgeboard Connectors Feature Summary

• Dual-edge configuration supports two rows of contacts for increased I/O density
• Vertical through-hole termination provides secure PCB attachment
• Gold-plated copper alloy contacts ensure corrosion resistance and conductivity
• Thermoplastic polyester insulation offers thermal stability within specified range

Edgeboard Connectors Applications

• Industrial control systems requiring robust card edge interfaces
• Telecommunications equipment utilizing standard board thicknesses
• Consumer electronics with high-density connection needs
• Medical devices demanding reliable electrical interconnects

Edgeboard Connectors Procurement Notes

Verify the specific ordering suffix to confirm contact plating thickness and flange characteristics, as these vary within the 387 series. Confirm that the target printed circuit board thickness matches the 1.57 mm specification to ensure proper mechanical fit. Check RoHS compliance status if environmental regulations apply to the final assembly. Ensure the dual-edge requirement aligns with the design before procurement.

Edgeboard Connectors Selection Notes

Select this component when a dual-row interface is required for a 1.57 mm thick board. The 0.156 inch pitch dictates the trace spacing on the edge card. Verify that the vertical orientation fits the enclosure constraints. Compare against single-edge variants if only one row of signals is necessary to reduce cost and profile.

Edgeboard Connectors Part Context

This part belongs to the EDAC 387 Series, which provides standardized card edge connectors for various industrial and commercial applications. The series offers multiple position counts and termination styles. The 387-028 variant specifically addresses designs needing 28 connections in a dual-row format, balancing density with standard spacing requirements.

Edgeboard Connectors Replacement Considerations

Direct substitutes include other EDAC 387 series parts with identical 28-position dual-edge specifications. Cross-reference the exact flange type and termination style to ensure mechanical compatibility. Generic equivalents may exist but require verification of pitch and board thickness tolerances.
