302-050-621-201

Edgeboard Connectors Overview

The EDAC Inc. 302-050-621-201 is a card edge connector from the 302 series, designed for dual-edge board applications. It features 50 positions with a 0.050 inch (1.27mm) contact spacing and 0.200 inch (5.08mm) row spacing. The connector utilizes gold-plated copper alloy contacts with a flash finish, housed in a black polyamide (PA66) insulator. It supports PCB thicknesses between 0.051 and 0.071 inches (1.30 to 1.80mm). The component employs a cantilever contact type for secure mating and offers a solder termination method. It operates within a temperature range of -55°C to 85°C and complies with RoHS3 standards.

Edgeboard Connectors Feature Summary

• Dual-edge configuration with cantilever spring contacts for reliable signal transmission
• Gold-plated terminals ensure corrosion resistance and low contact impedance
• Polyamide insulation provides thermal stability and mechanical durability
• Standardized spacing accommodates common double-sided circuit board designs

Edgeboard Connectors Applications

• Industrial control system interface modules
• Telecommunications equipment backplanes
• Computing hardware peripheral connections
• Test and measurement instrument boards

Edgeboard Connectors Procurement Notes

Verify that the specific part number matches the required 50-position count and dual-edge specification before ordering. Confirm that the supplier source is authorized by EDAC Inc. to ensure genuine components. Check for RoHS3 compliance documentation if environmental regulations apply to your assembly. Ensure storage conditions maintain moisture sensitivity level integrity prior to soldering processes.

Edgeboard Connectors Selection Notes

Select this model when a 1.27mm pitch is required for high-density dual-edge mounting. Consider the 0.200-inch row spacing for standard board layout constraints. Evaluate the black PA66 housing for compatibility with existing aesthetic or thermal requirements. Verify that the target PCB thickness falls within the specified 1.30 to 1.80mm range for proper cantilever engagement.

Edgeboard Connectors Part Context

This component belongs to the EDAC 302 series, which specializes in card edge connectors with fine 0.050-inch spacing. The series is engineered for robust performance in demanding electronic environments. The 302-050-621-201 variant specifically addresses needs for higher pin counts while maintaining compact form factors suitable for modern electronics manufacturing.

Edgeboard Connectors Replacement Considerations

Direct substitutes must match the 50-position count, 1.27mm pitch, and dual-edge geometry. Verify identical row spacing and contact plating specifications. Cross-reference mechanical dimensions to ensure board compatibility.
