302-050-221-201

Edgeboard Connectors Overview

The EDAC Inc. 302-050-221-201 is a dual-edge card edge connector from the 302 series, featuring 50 female positions with a 0.050-inch (1.27mm) pitch. It utilizes gold-plated copper alloy contacts and a black polyamide (PA66) insulator. Designed for board edge or straddle mount installation via solder termination, it accommodates card thicknesses of 0.051 to 0.071 inches (1.30 to 1.80mm). The component operates within a temperature range of -55°C to 85°C and complies with RoHS3 standards.

Edgeboard Connectors Feature Summary

• Dual-edge configuration with 50 female contacts for reliable signal transmission
• Gold-plated copper alloy contacts ensure corrosion resistance and low contact resistance
• Polyamide (PA66) insulation provides thermal stability and mechanical strength
• Straddle mount design secures the connector across the PCB edge

Edgeboard Connectors Applications

• Industrial control systems requiring robust board-to-board connections
• Telecommunications equipment utilizing standard card edge interfaces
• Consumer electronics with modular expansion capabilities
• Test and measurement devices needing stable high-density interconnects

Edgeboard Connectors Procurement Notes

Verify that the specific part number matches the required 50-position dual-edge specification. Confirm compatibility with the target PCB card thickness range of 1.30mm to 1.80mm. Ensure the mounting style aligns with the straddle mount requirement. Check for RoHS3 compliance if environmental regulations apply. Validate supplier authenticity through authorized distribution channels.

Edgeboard Connectors Selection Notes

Select this connector when a 1.27mm pitch dual-edge interface is necessary. Consider the 50-position count for circuit density requirements. Evaluate the straddle mount option for enhanced mechanical stability compared to surface mount alternatives. Assess the operating temperature range against environmental conditions. Verify that the gold plating meets conductivity needs for the application.

Edgeboard Connectors Part Context

This component belongs to EDAC's 302 series, which specializes in card edge connectors. The series offers various position counts and mounting styles. The 302-050-221-201 specifically addresses applications requiring a 50-contact dual-edge solution. It complements other EDAC products by providing standardized dimensions and reliable performance for electronic assemblies.

Edgeboard Connectors Replacement Considerations

Cross-reference with EDAC 302-050-221-201 equivalents from other manufacturers only if pinout and dimensions match exactly. Verify that substitute parts maintain the same 0.050-inch pitch and dual-edge configuration. Ensure material specifications for insulation and contact plating are comparable.
