305-076-500-278

Edgeboard Connectors Overview

The EDAC Inc. model 305-076-500-278 is a standard card edge connector from the 305 Series, designed for dual-edge board applications. It features 76 positions with a 3.96 mm (0.156 inch) pitch and supports a maximum PCB thickness of 1.57 mm. The connector utilizes gold-plated copper alloy contacts to ensure reliable signal transmission and has a current rating of 5 A. Constructed with a green thermoplastic housing, it offers robust insulation properties and environmental stability.

Edgeboard Connectors Feature Summary

• Dual-edge contact configuration accommodates double-sided circuit boards for increased I/O density.
• Gold-plated cantilever spring contacts provide low insertion force and high cycle durability.
• Green thermoplastic housing ensures electrical insulation and mechanical protection.
• Panel mount installation style facilitates secure integration into chassis or enclosure systems.

Edgeboard Connectors Applications

• Industrial control system backplanes
• Telecommunications equipment interconnects
• Test and measurement instrument modules
• Computing hardware peripheral interfaces

Edgeboard Connectors Procurement Notes

Verify that the specific part number matches the required dual-edge configuration and panel mount orientation. Confirm that the 76-position count aligns with the target PCB design. Ensure the 3.96 mm pitch specification is compatible with the mating card edge dimensions. Check for any RoHS compliance documentation requirements relevant to the procurement destination.

Edgeboard Connectors Selection Notes

Select this component when a dual-edge connection is necessary for the application architecture. The 5 A current rating suits moderate power distribution needs within the signal lines. Verify that the panel mount style fits the available chassis space. Consider the operating temperature range if the environment exceeds standard conditions.

Edgeboard Connectors Part Context

This component belongs to the EDAC 305 Series, which provides a range of standard card edge connectors. The series includes various position counts and mounting styles to support diverse electronic assembly requirements. The 305-076-500-278 variant specifically addresses the need for high-density dual-edge connectivity in professional electronics.

Edgeboard Connectors Replacement Considerations

Direct substitutes within the same series include models such as 305-076-500-202, which shares similar physical characteristics. Cross-series replacements require verification of pitch, position count, and mounting compatibility to ensure functional equivalence without redesigning the host board.
