305-054-521-508

Edgeboard Connectors Overview

The EDAC Inc. 305-054-521-508 is a standard card edge connector from the 305 Series, designed for dual-row applications with 54 positions. It features 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 connector utilizes gold-plated copper alloy contacts and a thermoplastic polyester insulator body. Rated for 5 A continuous current, it supports panel mount installation in a vertical orientation with solder pin termination.

Edgeboard Connectors Feature Summary

• Dual-row configuration with 54 positions for high-density interconnects
• Gold-plated copper alloy contacts ensure reliable signal transmission
• Accepts polarizing keys for secure board alignment
• Thermoplastic polyester housing provides structural stability

Edgeboard Connectors Applications

• Industrial control systems requiring robust card edge interfaces
• Telecommunications equipment with high-pin-count modules
• Test and measurement instrumentation boards
• Computing hardware expansion cards

Edgeboard Connectors Procurement Notes

Verify that the specific ordering suffix matches the required mounting style and flange characteristics. Confirm compliance with RoHS directives if environmental regulations apply to the end product. Ensure the PCB thickness falls within the specified acceptance range to guarantee proper mechanical engagement. Cross-reference the datasheet for insulation resistance and voltage ratings before final integration.

Edgeboard Connectors Selection Notes

Select this component when a dual-row interface with 3.96 mm pitch is required. The 54-position count suits applications needing substantial I/O density. Consider the vertical panel mount style for chassis-based designs. Verify that the 5 A current rating meets the electrical load requirements of the connected circuitry.

Edgeboard Connectors Part Context

This part belongs to the EDAC 305 Series, which offers various configurations of card edge connectors. The series is characterized by its standardized 3.96 mm spacing and compatibility with nominal 1.57 mm thick PCBs. Other variants in the series differ primarily in position count and mounting hardware options.

Edgeboard Connectors Replacement Considerations

Direct substitutes within the same series include parts like 305-054-521-201 or 305-054-521-278, provided the mounting flange and termination details are identical. Always verify mechanical dimensions and electrical ratings before swapping components.
