305-050-520-258

Edgeboard Connectors Overview

The EDAC Inc. 305-050-520-258 is a standard card edge connector from the 305 series, designed for dual-edge board applications. It features a 50-position configuration with a contact spacing of 0.156 inches (3.96 mm) and a row spacing of 0.140 inches (3.56 mm). The connector accepts printed circuit boards with a nominal thickness of 0.062 inches (1.57 mm). It utilizes female contacts made of copper alloy with gold plating, rated for 5 A current. The unit employs a panel mount style with a vertical orientation and solder pin termination.

Edgeboard Connectors Feature Summary

• Dual-row female contact configuration for non-specified dual-edge PCBs
• Low-profile insulator body constructed from thermoplastic polyester
• Gold-plated copper alloy contacts ensuring reliable signal transmission
• Panel mount design with vertical orientation and solder pin termination

Edgeboard Connectors Applications

• Industrial control systems requiring robust card edge interfaces
• Telecommunications equipment utilizing dual-edge module connections
• Test and measurement instrumentation with standardized board formats
• Computing hardware employing high-density vertical mounting solutions

Edgeboard Connectors Procurement Notes

Verify that the specific part number matches the required 50-position count and 3.96 mm pitch before ordering. Confirm that the target application supports the specified 1.57 mm board thickness to ensure proper mechanical engagement. Check regional availability as distribution status may vary by location. Ensure compliance with RoHS3 specifications if environmental regulations apply to the final assembly process.

Edgeboard Connectors Selection Notes

Select this component when a dual-edge female connector is required for vertical panel mounting. The 3.96 mm pitch suits applications needing moderate density without excessive board space consumption. Verify that the 5 A current rating aligns with the electrical requirements of the connected circuitry. Consider the low-profile body height if vertical clearance within the enclosure is limited during the design phase.

Edgeboard Connectors Part Context

This component belongs to the EDAC 305 Series, which offers various mounting options and position counts. The series is characterized by its .156 inch contact spacing and compatibility with standard dual-edge boards. Similar parts in the lineup differ primarily in position count and specific mounting configurations while maintaining consistent electrical performance and material standards across the family.

Edgeboard Connectors Replacement Considerations

Direct substitutes within the same series include 305-050-500-202 and 305-050-520-201. These alternatives share identical positioning and pitch but may differ in flange characteristics or packaging quantities. Verify mechanical fit and terminal type compatibility before swapping components in existing designs.
