307-076-522-278

Edgeboard Connectors Overview

The EDAC Inc. 307-076-522-278 is a standard card edge connector from the 307 series, designed for dual-edge female connections with 76 positions. It features a contact spacing of 3.96 mm (0.156 inches) and a row spacing of 5.08 mm (0.200 inches). The component accepts printed circuit boards with a nominal thickness of 1.57 mm (0.062 inches). Constructed with copper alloy contacts plated in gold and a green thermoplastic polyester insulator, it supports a current rating of 5 A. The connector utilizes a half-beadle terminal type and is available in panel mount configurations.

Edgeboard Connectors Feature Summary

• Dual-edge female design accommodates double-sided PCBs
• Low profile insulator body for compact integration
• Gold-plated copper alloy contacts ensure reliable conductivity
• Thermoplastic polyester housing provides thermal stability

Edgeboard Connectors Applications

• Industrial control systems requiring robust interconnects
• Telecommunications equipment backplanes
• Test and measurement instrumentation modules
• Computer peripheral interface cards

Edgeboard Connectors Procurement Notes

Verify the specific mounting style required for the application, as the 307 series includes both PCB mount and panel mount variants. Confirm that the target PCB thickness falls within the specified range of 1.37 mm to 1.78 mm to ensure proper contact engagement. Check RoHS compliance status if environmental regulations apply to the end product. Ensure the ordering suffix matches the desired termination method and flange characteristics.

Edgeboard Connectors Selection Notes

Select this component when a high-density connection with 76 positions is necessary for double-sided edge cards. The 3.96 mm pitch offers a balance between signal density and mechanical reliability. Consider the 5 A current rating for power distribution needs within the module. The green color coding may assist in visual identification during assembly processes compared to standard black connectors.

Edgeboard Connectors Part Context

This part belongs to the EDAC 307 Series, which specializes in standard card edge connectors. The series is characterized by its consistent 3.96 mm contact spacing and compatibility with 1.57 mm thick PCBs. Variations within the series differ primarily by position count, mounting style, and termination type, allowing for modular design approaches in electronic hardware development.

Edgeboard Connectors Replacement Considerations

Direct substitutes are not explicitly listed in public documentation. Cross-reference with other EDAC 307 series parts sharing the same 76-position count and 3.96 mm pitch. Verify mechanical footprint and electrical ratings before substituting with generic equivalents.
