305-040-500-258

Edgeboard Connectors Overview

The EDAC Inc. 305-040-500-258 is a standard card edge connector from the 305 series, designed for panel mount applications with a vertical orientation. It features 40 positions arranged in two rows, providing a total contact count of 40. The connector utilizes a 3.96 mm (0.156 inch) pitch and is engineered to accommodate PCB thicknesses ranging from 1.37 mm to 1.78 mm (0.054 to 0.070 inches). Contacts are constructed from copper alloy with gold plating and employ a solder lug termination method. Rated for 5 A current, it operates within a temperature range of -40°C to +105°C.

Edgeboard Connectors Feature Summary

Dual-row female configuration with gold-plated copper alloy contacts for reliable signal transmission
Solder lug termination style ensures secure mechanical and electrical connection to the printed circuit board
Thermoplastic insulator housing provides structural integrity and electrical insulation properties

Edgeboard Connectors Applications

Industrial control systems requiring robust panel-mounted interconnects
Telecommunications equipment utilizing dual-edge card edge interfaces
Test and measurement instrumentation boards

Edgeboard Connectors Procurement Notes

Verify component authenticity by cross-referencing the manufacturer part number 305-040-500-258 with official EDAC Inc. documentation. Confirm that the specific ordering suffix matches the required termination type and contact finish specifications. Ensure compliance with RoHS directives as indicated in the product datasheet before integration into final assemblies.

Edgeboard Connectors Selection Notes

Select this connector when a vertical, panel-mount solution with a 3.96 mm pitch is required. The 40-position dual-row layout supports high-density connections on double-sided cards. Verify that the target PCB thickness falls within the specified 1.37 mm to 1.78 mm range to ensure proper contact engagement and mechanical stability during operation.

Edgeboard Connectors Part Context

This component belongs to the EDAC 305 series of standard card edge connectors. The series offers various position counts and termination options. The 305-040 variant specifically denotes the 40-position configuration. This model represents a specialized industrial-grade interconnect solution distinct from other EDAC series such as the 315 or 346 families.
