Edgeboard Connectors Overview

The EDAC Inc. 305-028-556-202 is a dual-row female card edge connector designed for board-edge mounting. It features 28 positions with a 0.156-inch (3.96mm) pitch and accepts non-specified dual-edge cards. The contacts are gold-plated copper alloy with a thickness of 10.0µin (0.25µm). Insulation is provided by green thermoplastic polyester, supporting a temperature range of -40°C to 105°C.

Edgeboard Connectors Feature Summary

Dual-row configuration for high-density signal routing
Gold-plated semi-crimped contacts for reliable conductivity
Thermoplastic polyester insulation for thermal stability

Edgeboard Connectors Applications

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

Edgeboard Connectors Procurement Notes

Verify the specific pin count and row configuration against the target PCB design requirements. Confirm that the mating card thickness falls within the specified mechanical tolerances for proper insertion force and contact retention. Ensure compliance with RoHS3 standards if required by the end application regulations.

Edgeboard Connectors Selection Notes

Select this component when a dual-row interface with a 3.96mm pitch is required for vertical panel or board-edge mounting. Consider the gold plating thickness for corrosion resistance needs and verify that the operating temperature range aligns with the environmental conditions of the deployment site.

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, providing a modular solution for connecting edge-board circuits to parent systems in compact electronic assemblies.
