305-076-556-212

Edgeboard Connectors Overview

The EDAC Inc. 305-076-556-212 is a standard card edge connector from the 305 series, designed for panel mount applications. It features a dual female configuration with 76 positions and a 3.96 mm (0.156 inch) pitch. The connector utilizes gold-plated copper alloy contacts and solder pin termination. It accommodates board thicknesses ranging from 1.37 mm to 1.78 mm and operates within a temperature range of -40°C to 105°C.

Edgeboard Connectors Feature Summary

• Dual edge female contact configuration for non-specified card types
• Gold-plated copper alloy contacts for reliable signal transmission
• Panel mount installation style with vertical orientation
• Solder pin termination for secure PCB attachment

Edgeboard Connectors Applications

• Industrial control systems requiring robust interconnects
• Communication equipment backplanes
• Test and measurement instrumentation interfaces
• Automotive electronics modules

Edgeboard Connectors Procurement Notes

Verify the specific ordering suffix against the official EDAC datasheet to ensure correct contact plating thickness and insulation material properties. Confirm that the target application board thickness falls within the specified 1.37 mm to 1.78 mm range to guarantee proper mechanical engagement. Check RoHS compliance status if required by project specifications.

Edgeboard Connectors Selection Notes

Select this component when a high-density 76-position interface is required in a panel-mount form factor. The 3.96 mm pitch offers a balance between density and spacing reliability. Ensure the mating card edge design matches the dual female receptacle requirements and that the operating environment stays within the -40°C to 105°C thermal limits defined for the series.

Edgeboard Connectors Part Context

This part belongs to the EDAC 305 series of standard card edge connectors, which are widely used in industrial and commercial electronics. The series provides various position counts and mounting options, with the 305-076 variant specifically addressing higher I/O density needs in panel-mounted architectures.

Edgeboard Connectors Replacement Considerations

Cross-reference with other EDAC 305 series parts sharing the same 76-position count and 3.96 mm pitch. Verify mechanical dimensions and electrical ratings before substituting with alternative manufacturers' equivalents to ensure compatibility with existing panel cutouts and mating cards.
