302-048-321-201

Edgeboard Connectors Overview

The EDAC Inc. 302-048-321-201 is a dual-edge card edge connector from the 302 series, designed for surface-mount or through-hole termination on printed circuit boards. It features 48 positions with a 0.050-inch (1.27mm) contact pitch and supports non-specified dual-edge cards. The connector utilizes gold-plated contacts over a copper alloy base, housed in a black polyamide (PA66) insulator. It accommodates board thicknesses ranging from 0.051 to 0.071 inches (1.30mm to 1.80mm) and operates within a temperature range of -55°C to 85°C.

Edgeboard Connectors Feature Summary

• Dual-edge configuration with 48 female contacts for reliable signal transmission
• Gold-plated suspension-type contacts ensure low contact resistance and durability
• Polyamide (PA66) insulation provides high thermal stability and mechanical strength
• Compatible with standard non-specified dual-edge card thicknesses

Edgeboard Connectors Applications

• Industrial control systems requiring robust interconnects
• Telecommunications equipment with dense signal routing needs
• Automotive electronics operating in varying thermal conditions
• Test and measurement instrumentation interfaces

Edgeboard Connectors Procurement Notes

Verify that the specific order matches the 302 series designation and 48-position count. Confirm the termination style aligns with your PCB layout requirements. Ensure the supplier provides documentation confirming RoHS3 compliance and the correct material specifications for the polyamide housing and gold plating thickness.

Edgeboard Connectors Selection Notes

Select this component when a compact 1.27mm pitch is required for dual-edge card applications. Consider the -55°C to 85°C operating range against your environmental constraints. Evaluate the mechanical fit for the specified card thickness range to ensure proper retention and contact engagement during assembly.

Edgeboard Connectors Part Context

This part belongs to EDAC's 302 series, which focuses on high-density card edge connectors. The series is characterized by its fine 0.050-inch pitch and versatile mounting options. It serves as a critical interface component in modern electronic assemblies where space efficiency and connection reliability are paramount.

Edgeboard Connectors Replacement Considerations

Cross-reference with other EDAC 302 series variants for different pin counts. Verify compatibility with alternative manufacturers offering similar 1.27mm pitch dual-edge connectors, ensuring identical mechanical dimensions and electrical ratings before substitution.
