305-050-556-278

Edgeboard Connectors Overview

The EDAC 305-050-556-278 is a standard card edge connector from the 305 Series, designed for dual-row female connections. It features a 3.96 mm (0.156 inch) contact pitch and accommodates printed circuit boards with a nominal thickness of 1.57 mm (0.062 inch). The component utilizes copper alloy contacts with gold plating to ensure reliable signal transmission. Rated for 5 A current at temperatures ranging from -40°C to +105°C, it employs a solder pin termination method. This panel-mount header provides a secure interface for vertical installation in electronic assemblies.

Edgeboard Connectors Procurement Notes

Verify the specific ordering suffix against the manufacturer's official datasheet to confirm exact physical dimensions and termination style. Ensure compatibility with the target PCB thickness of 1.57 mm. Confirm that the required current rating of 5 A aligns with the application's electrical load requirements before finalizing procurement.

Edgeboard Connectors Selection Notes

Select this connector when a dual-row female interface is required for 1.57 mm thick cards. The 3.96 mm pitch dictates the trace spacing on the mating board. Verify that the vertical panel mount style fits the enclosure constraints. Consider the operating temperature range of -40°C to +105°C for environmental suitability.
