305-070-520-508

Edgeboard Connectors Overview

The EDAC 305-070-520-508 is a standard card edge connector featuring 70 positions arranged in two rows. It utilizes a 3.96 mm pitch and accepts PCBs with a thickness of 1.57 mm. The contacts are gold-plated copper alloy, rated for 5 A continuous current and 1800 VACrms insulation. Designed for panel mount installation at a vertical angle, it employs solder pin termination. The housing is constructed from thermoplastic material, ensuring an insulation resistance of 5 GOhms across an operating temperature range of -40 C to +105 C.

Edgeboard Connectors Feature Summary

• Accepts between-contact and in-contact polarizing keys for secure alignment
• Dual female contact configuration with gold plating for reliable signal transmission
• Vertical panel mount design facilitates structured board integration

Edgeboard Connectors Applications

• Industrial control systems requiring robust card edge interfaces
• Communication equipment utilizing standardized module connections
• Medical devices needing high insulation resistance and thermal stability

Edgeboard Connectors Procurement Notes

Verify the specific ordering suffix against official EDAC documentation to confirm exact physical dimensions and termination style. Confirm that the required polarizing key compatibility matches the intended application design. Ensure the target PCB thickness aligns precisely with the specified 1.57 mm requirement for proper mechanical engagement. Cross-reference the voltage rating with system operational limits to guarantee safety compliance during procurement.

Edgeboard Connectors Selection Notes

Select this component when a dual-row interface with a 3.96 mm pitch is required for panel-mounted applications. Consider the 5 A current rating and 1800 VACrms insulation capability for high-reliability environments. Evaluate the vertical mounting orientation against available panel space constraints. Verify that the thermoplastic housing material meets the environmental exposure requirements for the intended deployment scenario.

Edgeboard Connectors Part Context

This part belongs to the EDAC 305 series of standard card edge connectors. The series provides various position counts and termination options while maintaining consistent electrical characteristics. The 305-070-520-508 specifically addresses needs for higher density connections within the established 3.96 mm spacing framework used across industrial and commercial electronic assemblies.

Edgeboard Connectors Replacement Considerations

Consult official EDAC substitution guides for verified alternative part numbers within the 305 series or compatible families. Do not assume interchangeability with generic card edge connectors due to specific dimensional tolerances.
