305-032-556-578

Edgeboard Connectors Overview

The EDAC Inc. 305-032-556-578 is a standard card edge connector header featuring 32 positions arranged in a dual-row configuration. It utilizes a 3.96 mm (0.156 inch) contact spacing and accepts printed circuit boards with a nominal thickness of 1.57 mm (0.062 inch). The component employs gold-plated copper alloy contacts with a solder pin termination type for secure board attachment. Designed for panel mount installation at a vertical angle, it operates within a temperature range of -40°C to +105°C and carries an electrical rating of 5 A.

Edgeboard Connectors Feature Summary

• Dual-edge female contact design accommodates non-specified dual-edge PCBs for reliable signal transmission.
• Gold-plated copper alloy contacts ensure low contact resistance and corrosion resistance over time.
• Vertical panel mount style provides stable mechanical support and alignment for card insertion.

Edgeboard Connectors Applications

• Industrial control system backplanes
• Telecommunications equipment interconnects
• Test and measurement instrument modules

Edgeboard Connectors Procurement Notes

Verify the specific suffix codes against the manufacturer's ordering guide to confirm exact plating thickness and insulator material variations. Ensure compatibility with the target PCB thickness tolerance of 1.57 mm to maintain proper contact engagement. Confirm that the application environment stays within the specified -40°C to +105°C operating range to guarantee long-term reliability and performance stability.

Edgeboard Connectors Selection Notes

Select this model when a 32-position dual-row interface is required for vertical panel mounting applications. The 3.96 mm pitch suits standard board layouts while the 5 A rating supports moderate current loads. Consider the gold plating for environments requiring high cycle durability and low maintenance. Verify that the housing material meets the thermal requirements of the specific deployment scenario.

Edgeboard Connectors Part Context

This component belongs to the EDAC 305 series of standard card edge connectors, which are widely used in modular electronic systems. The series offers various position counts and row configurations to suit different density requirements. The 305 series is characterized by its robust construction and consistent electrical performance across multiple industrial sectors.

Edgeboard Connectors Replacement Considerations

Compatible substitutes within the same series include models such as 305-022-556-568 and 305-054-556-278, which share identical pitch and mounting characteristics but differ in position count. Cross-series replacements require verification of mechanical dimensions and electrical ratings to ensure functional equivalence.
