305-048-521-508

Edgeboard Connectors Overview

The EDAC Inc. 305-048-521-508 is a standard card edge connector featuring 48 positions arranged in a dual-row configuration with a 3.96 mm (0.156 inch) contact spacing and 3.56 mm row spacing. Designed for vertical panel mount installation, it utilizes gold-plated copper alloy contacts with solder pin termination to ensure reliable electrical connections. The connector accommodates printed circuit boards with a nominal thickness of 1.57 mm (0.062 inch). Constructed with a thermoplastic insulator body, this component operates within a temperature range of -40°C to +105°C and supports a current rating of 5 A per contact.

• Vertical panel mount orientation with solder pin termination

Edgeboard Connectors Applications

• Industrial control system interconnects
• Telecommunications equipment backplanes
• Test and measurement instrument interfaces
• Automotive electronic module connections

Edgeboard Connectors Procurement Notes

Verify the specific ordering suffix against the manufacturer's official datasheet to confirm plating thickness and material specifications. Ensure compatibility with the target PCB thickness of 1.57 mm before procurement. Confirm that the vertical panel mount style aligns with the mechanical enclosure requirements. Cross-reference the 48-position count and 3.96 mm pitch with the system design constraints to prevent interface mismatches during assembly.

Edgeboard Connectors Selection Notes

Select this component when a robust, high-current connection is required for thick PCBs up to 1.57 mm. The dual-row layout maximizes I/O density while maintaining a wide 3.96 mm pitch for ease of handling. Consider the vertical mounting profile for space-constrained panel applications. The gold plating offers durability in environments where oxidation resistance is critical for long-term signal integrity.

Edgeboard Connectors Part Context

This part belongs to the EDAC 305 series of standard card edge connectors, which are engineered for general-purpose industrial and commercial applications. The series provides various position counts and row configurations to suit different board densities. The 305 series is characterized by its durable construction and standardized dimensions, ensuring interchangeability across different system designs requiring reliable board-to-board or board-to-panel connectivity.

Edgeboard Connectors Replacement Considerations

Direct substitutes include other EDAC 305 series variants with identical 48-position, dual-row, 3.96 mm pitch specifications. Verify that any replacement maintains the same 1.57 mm board thickness tolerance and vertical panel mount orientation. Ensure the alternative component matches the gold-plated contact finish and solder pin termination type for equivalent electrical performance.
