305-038-521-502

Edgeboard Connectors Overview

The EDAC Inc. 305-038-521-502 is a standard card edge connector from the 305 series, designed for dual-edge female connections. It features 38 positions arranged in two rows with a 3.96 mm (0.156 inch) pitch. The contacts are made of copper alloy with gold plating and utilize a semi-corrugated type for reliable engagement. Rated for 5 A current, it supports PCB thicknesses between 1.37 mm and 1.78 mm. The housing is green thermoplastic polyester, operating within -40°C to +105°C.

Edgeboard Connectors Feature Summary

• Dual-row configuration with 38 total positions for high-density signal routing
• Semi-corrugated contact design ensures secure mating with dual-edge cards
• Gold-plated copper alloy contacts provide corrosion resistance and low contact impedance
• Thermoplastic polyester insulation offers stability across a wide temperature range

Edgeboard Connectors Applications

• Panel-mounted vertical interconnects for industrial control systems
• Signal routing in telecommunications equipment requiring robust edge-card interfaces
• Test and measurement instrumentation utilizing standardized card modules

Edgeboard Connectors Procurement Notes

Verify the specific suffix codes against official EDAC documentation to confirm exact pin count, row configuration, and termination style. Ensure compatibility with target PCB thickness limits and panel mounting requirements before integration. Cross-reference datasheet specifications for environmental ratings and current capacity to validate suitability for the intended operational environment.

Edgeboard Connectors Selection Notes

Select this component when a dual-row, 38-position interface is required with a 3.96 mm pitch. It is suitable for applications demanding vertical panel mounting and solder pin termination. Consider the gold-plated semi-corrugated contacts for enhanced durability in repeated insertion cycles compared to standard flat contacts.

Edgeboard Connectors Part Context

This part belongs to the EDAC 305 Series, which provides various mounting options including panel mount and through-hole configurations. The series supports multiple row counts and pitch variations, allowing designers to scale connectivity density while maintaining consistent mechanical and electrical standards across different product lines.

Edgeboard Connectors Replacement Considerations

Direct substitutes include other EDAC 305 series variants with identical 38-position dual-row layouts and 3.96 mm pitch, such as 305-038-520-502 or 305-038-521-504, provided mounting styles and termination types match the design requirements.
