305-048-521-578

Edgeboard Connectors Overview

The EDAC Inc. 305-048-521-578 is a standard card edge connector from the 305 series, designed for vertical panel mounting applications. It features a dual-row configuration with 48 positions and a contact spacing of 0.156 inches (3.96 mm). The connector utilizes gold-plated copper alloy contacts with a half-beam termination type, suitable for solder pin end connections. It accepts printed circuit boards with a nominal thickness of 0.062 inches (1.57 mm) and supports a continuous current rating of 5 A. The insulator body is constructed from thermoplastic material, providing an operating temperature range between -40°C and +105°C.

Edgeboard Connectors Feature Summary

• Accepts between-contact and in-contact polarizing keys for secure positioning
• Features low profile insulator body design for compact integration
• Utilizes gold-plated half-beam contacts for reliable signal transmission

Edgeboard Connectors Applications

• Industrial control systems requiring robust panel-mounted interconnects
• Communication equipment utilizing standard card edge interfaces
• Embedded applications needing high-reliability vertical board connections

Edgeboard Connectors Procurement Notes

Verify the specific ordering suffix to ensure correct contact plating and insulation material specifications. Confirm that the target application requires a 0.062-inch board thickness compatibility. Check regional distribution availability as stock levels may vary by region. Ensure compliance with RoHS directives if required for the specific project environment.

Edgeboard Connectors Selection Notes

Select this component when a dual-row, 48-position card edge connector is required for vertical panel installation. The 3.96 mm pitch is suitable for general-purpose industrial and communication boards. Consider the 5 A current rating and thermal limits when designing the power distribution network. Verify mechanical clearance for the polarizing key options if used.

Edgeboard Connectors Part Context

This part belongs to the EDAC 305 series of standard card edge connectors, which are widely used in various electronic assemblies. The series offers multiple position counts and row configurations to accommodate different board densities. The 305 series is characterized by its durability and standardized dimensions, making it a common choice for replacement or new designs in the connector market.

Edgeboard Connectors Replacement Considerations

Direct substitutes within the same series include parts with identical row and position counts but different suffixes for variations in plating or housing color. Cross-series replacements require matching the 3.96 mm pitch and 0.062 inch board thickness constraints. Always verify electrical ratings and mechanical mounting angles before substituting.
