305-050-521-207

Edgeboard Connectors Overview

The EDAC 305-050-521-207 is a standard card edge connector from the 305 series, designed for dual-edge board insertion. It features 50 positions with a 3.96 mm (0.156 inch) pitch and supports a maximum PCB thickness of 1.57 mm. The connector utilizes gold-plated copper alloy contacts and a thermoplastic housing. Rated for 5 A continuous current and 1800 VACrms insulation, it operates within a temperature range of -40°C to +105°C. This vertical panel-mount header uses solder pin termination.

Edgeboard Connectors Feature Summary

• Accepts between-contact and in-contact polarizing keys for secure board alignment
• Dual-row female contact configuration for high-density signal routing
• Gold-plated contacts ensure reliable conductivity and corrosion resistance
• Thermoplastic insulator provides stable mechanical support and electrical isolation

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 position count and termination style against project requirements before ordering. Confirm that the polarizing key compatibility matches the target PCB design. Ensure the operating environment falls within the specified thermal limits. Cross-reference the manufacturer datasheet for precise dimensional tolerances and mating force specifications.

Edgeboard Connectors Selection Notes

Select this component when a dual-edge card interface with a 3.96 mm pitch is required. The 50-position layout suits applications needing moderate signal density. Verify that the panel mount orientation aligns with the chassis design. Consider the 5 A rating for power distribution needs alongside signal lines.
