305-028-521-512

Edgeboard Connectors Overview

The EDAC Inc. 305-028-521-512 is a standard card edge connector from the 305 series, designed for vertical panel mount applications. It features 28 positions with a 0.156-inch (3.96 mm) pitch and utilizes dual female contacts. The connector employs solder pin termination and gold-plated copper alloy contacts to ensure reliable signal transmission. Constructed with a thermoplastic polyester insulator, it supports board thicknesses within specified mechanical limits and operates reliably across a temperature range of -40°C to +105°C.

Edgeboard Connectors Feature Summary

• Vertical panel mount configuration for secure installation
• Dual female contact design for edgeboard insertion
• Gold-plated copper alloy contacts for corrosion resistance
• Thermoplastic polyester insulation for thermal stability

Edgeboard Connectors Applications

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

Edgeboard Connectors Procurement Notes

Verify the specific ordering suffix against the manufacturer's current datasheet to confirm exact contact plating thickness and material specifications. Ensure compatibility with the target PCB edge thickness and mounting hole dimensions before procurement. Confirm RoHS compliance status and check for any regional distribution restrictions or supply limitations associated with this specific part number variant.

Edgeboard Connectors Selection Notes

Select this component when a vertical, dual-row card edge interface is required for panel-mounted assemblies. The 28-position count and 3.96 mm pitch define the electrical density and physical footprint. Consider the thermoplastic polyester housing for environments requiring stable dielectric properties and the gold finish for long-term reliability in high-cycle mating scenarios.

Edgeboard Connectors Part Context

This part belongs to the EDAC 305 series of standard card edge connectors, which are engineered for general-purpose electronic interconnections. The series offers various position counts and mounting styles to accommodate diverse board-to-board and board-to-panel connectivity needs. The 305-028-521-512 specifically addresses applications needing a compact, high-density vertical connection solution with durable metallic contacts.

Edgeboard Connectors Replacement Considerations

Consult the official EDAC 305 Series Ordering Guide for verified substitute part numbers. Cross-reference mechanical dimensions, pin count, and pitch to ensure functional equivalence. Verify that any alternative maintains the same vertical orientation and termination style to fit existing panel cutouts and PCB layouts.
