305-050-555-578

Edgeboard Connectors Overview

The EDAC Inc. 305-050-555-578 is a standard card edge connector from the 305 series, designed for dual-edge board applications. It features 50 positions with a 3.96 mm (0.156 inch) contact spacing and a 2-row configuration. The connector utilizes female half-beam contacts made of copper alloy with gold plating. It supports PCB thicknesses ranging from 1.37 mm to 1.78 mm and operates within a temperature range of -40°C to +105°C. The housing is constructed from green thermoplastic polyester, ensuring reliable insulation.

Edgeboard Connectors Feature Summary

• Dual-row female contact configuration for secure dual-edge board mating
• Gold-plated copper alloy half-beam contacts for corrosion resistance
• Thermoplastic polyester insulator body providing stable electrical isolation
• Panel mount design with flange features for fixed installation

Edgeboard Connectors Applications

• Industrial control system backplanes
• Telecommunications equipment interconnects
• Test and measurement instrument modules
• Computing hardware expansion slots

Edgeboard Connectors Procurement Notes

Verify the specific suffix codes against official EDAC documentation to confirm exact plating thickness and material specifications. Ensure compatibility with target PCB dimensions, particularly the required thickness range of 1.37 mm to 1.78 mm. Confirm that the panel mounting requirements align with the connector's flange characteristics before finalizing procurement orders.

Edgeboard Connectors Selection Notes

Select this component when a dual-edge connection is required with a 3.96 mm pitch. It is suitable for environments requiring operation between -40°C and +105°C. Consider the panel mount style and the need for gold-plated contacts in high-reliability applications. Verify that the 50-position count matches the circuit design requirements.

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 options, all sharing a consistent 3.96 mm pitch. The 305-050-555-578 specifically provides a 50-position dual-row interface, fitting into the broader family of connectors designed for robust industrial and commercial electronic interconnections.

Edgeboard Connectors Replacement Considerations

Direct substitutes within the same series include parts with identical pitch and row configurations but different position counts, such as 305-048-555-578 or 305-052-555-578. Cross-series replacements require verification of mechanical fit and electrical ratings.
