305-082-556-278

Edgeboard Connectors Overview

The EDAC Inc. 305-082-556-278 is a standard card edge connector from the 305 series, designed for dual-edge board insertion. It features 82 positions with a contact spacing of 3.96 mm (0.156 inches) and a row spacing of 3.56 mm (0.140 inches). The connector accepts printed circuit boards with a nominal thickness of 1.57 mm (0.062 inches). Constructed with gold-plated contacts on a copper alloy base, it utilizes a green thermoplastic insulator body. The component supports vertical panel mounting via solder pin termination.

Edgeboard Connectors Feature Summary

• Dual female contact configuration accommodates double-sided card edge PCBs
• Gold-plated copper alloy contacts ensure reliable signal transmission
• Low-profile insulator body design facilitates compact assembly integration

Edgeboard Connectors Applications

• Medical interconnect systems requiring durable connections
• Agricultural technology equipment operating in harsh environments
• Industrial control panels utilizing vertical panel mount headers

Edgeboard Connectors Procurement Notes

Verify specific lot codes and RoHS compliance status directly with the manufacturer or authorized distributors before procurement. Confirm that the ordering suffix corresponds to the exact insulation color and termination style required for the target application. Ensure compatibility with the specified 1.57 mm board thickness to prevent mechanical stress during insertion. Cross-reference the datasheet revision date to confirm current manufacturing specifications.

Edgeboard Connectors Selection Notes

Select this component when a dual-row connection is required for 82-position interfaces. The 3.96 mm pitch suits applications needing robust mechanical retention for thicker PCBs. Consider the vertical panel mount style for chassis integration where space constraints favor low-profile designs. Verify thermal ratings against operational requirements, as the thermoplastic body supports elevated temperatures.

Edgeboard Connectors Part Context

This part belongs to the EDAC 305 series of standard card edge connectors. The series offers various position counts and termination options for diverse electronic assemblies. The 305 series is characterized by its reliability in demanding sectors such as medical and agricultural technologies. This specific model represents a high-density solution within the family.

Edgeboard Connectors Replacement Considerations

Direct substitutes include other EDAC 305 series variants with matching 82 positions and 3.96 mm pitch, such as 305-082-556-507. Verify that alternative parts maintain the same dual-edge female configuration and gold plating specification to ensure functional equivalence.
