305-050-520-504

Edgeboard Connectors Overview

The EDAC Inc. 305-050-520-504 is a standard card edge connector from the 305 series, designed for dual-edge board applications. It features 50 positions with a 3.96 mm (0.156 inch) pitch and supports two rows of contacts. The connector utilizes gold-plated copper alloy terminals with a thickness of 10.0 µin (0.25 µm) to ensure reliable signal transmission. It accommodates PCB thicknesses ranging from 1.37 mm to 1.78 mm (0.054 to 0.070 inches). Rated for 5 A current, it operates within a temperature range of -40°C to +105°C and employs a thermoplastic polyester insulator.

Edgeboard Connectors Feature Summary

• Dual female contact configuration for non-specified dual-edge card insertion
• Solder pin termination method for secure PCB mounting
• Gold plating on mating areas to enhance conductivity and corrosion resistance
• Thermoplastic polyester insulation providing stable dielectric properties

Edgeboard Connectors Applications

• Panel-mounted electronic interconnect systems
• Industrial control module interfaces
• Telecommunications equipment backplanes
• Test and measurement instrument connections

Edgeboard Connectors Procurement Notes

Verify the specific ordering suffix against the manufacturer's official 305 Series Ordering Guide to confirm terminal plating specifications and flange dimensions. Ensure compatibility with the target PCB thickness range of 1.37 mm to 1.78 mm. Confirm that the required current rating of 5 A aligns with the system design parameters before finalizing procurement.

Edgeboard Connectors Selection Notes

Select this component when a vertical panel-mount solution is required for dual-edge cards. The 3.96 mm pitch dictates the trace spacing on the mating PCB. Verify that the housing color and flange diameter meet mechanical enclosure constraints. Consider the solder pin end type for through-hole assembly processes and ensure the operating temperature range suits the environmental conditions.

Edgeboard Connectors Part Context

This part belongs to the EDAC 305 series of standard card edge connectors, which are widely used in industrial and commercial electronics. The series offers various position counts and mounting styles. The 305-050 variant specifically provides a high-density connection option for dual-edge boards, balancing mechanical stability with electrical performance in compact form factors.

Edgeboard Connectors Replacement Considerations

Consult the EDAC 305 Series Ordering Guide for direct substitutes with identical pitch and position counts but different flange or plating options. Cross-reference with other EDAC series such as 315 or 355 only if mechanical footprint and electrical ratings are fully compatible.
