305-084-556-268

Edgeboard Connectors Overview

The EDAC Inc. 305-084-556-268 is a standard card edge connector from the 305 series, designed for panel mounting in a vertical orientation. It features an 84-position dual-row configuration with a 3.96 mm (0.156 inch) pitch. The contacts are made of copper alloy and are gold-plated to ensure reliable signal transmission. Rated for 5 A current, it supports PCB thicknesses of 1.57 mm. The housing utilizes thermoplastic material, providing insulation resistance of 5 GOhms and operating within a temperature range of -40°C to +105°C.

Edgeboard Connectors Feature Summary

• Dual-row female contact configuration for high-density board connections
• Gold-plated copper alloy contacts for enhanced conductivity and corrosion resistance
• Thermoplastic housing ensures stable insulation and environmental durability

Edgeboard Connectors Applications

• Industrial control system interconnects
• Telecommunications equipment backplanes
• Test and measurement instrument modules

Edgeboard Connectors Procurement Notes

Verify the specific suffix codes against official EDAC documentation to confirm exact plating thickness and housing color variations. Ensure compatibility with the target PCB stack-up and verify that the 1.57 mm board thickness requirement aligns with the design specifications before procurement.

Edgeboard Connectors Selection Notes

Select this component when a high-pin-count, dual-row interface is required for panel-mounted applications. The 3.96 mm pitch accommodates larger signal traces compared to finer pitches. Confirm that the vertical mounting style fits the enclosure constraints and that the 5 A rating meets the circuit load requirements.

Edgeboard Connectors Part Context

This part belongs to the EDAC 305 series of standard card edge connectors. The series offers various position counts and mounting styles, utilizing a consistent 3.96 mm pitch architecture. The 305-084 variant specifically addresses applications requiring 84 connection points in a compact dual-row format.

Edgeboard Connectors Replacement Considerations

Cross-reference with other EDAC 305 series parts sharing the same 3.96 mm pitch and dual-row layout. Verify mechanical dimensions and pinout compatibility before substituting with alternative manufacturers' equivalents.
