305-048-520-568

Edgeboard Connectors Overview

The EDAC Inc. 305-048-520-568 is a standard card edge connector from the 305 Series, designed for dual-edge board insertion. It features 48 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 half-bead contact type to ensure reliable signal transmission. It is rated for 5 A continuous current and operates within a temperature range of -40°C to +105°C. The housing is constructed from green thermoplastic polyester, accommodating PCB thicknesses between 1.37 mm and 1.78 mm.

Edgeboard Connectors Feature Summary

• Dual-edge female connector design for secure board retention
• Gold-plated copper alloy contacts for corrosion resistance
• Thermoplastic polyester housing for thermal stability
• Supports between-contact and in-contact polarizing keys

Edgeboard Connectors Applications

• Industrial control system backplanes
• Telecommunications equipment interconnects
• Test and measurement instrument modules
• Embedded computing hardware interfaces

Edgeboard Connectors Procurement Notes

Verify that the specific ordering suffix matches the required flange and termination style, as variations exist within the 305 series. Confirm RoHS compliance status for your region's regulatory requirements. Ensure the PCB thickness falls within the specified 1.37 mm to 1.78 mm range to guarantee proper mechanical engagement. Check for availability constraints as this component may be subject to order-based manufacturing schedules rather than immediate stock delivery.

Edgeboard Connectors Selection Notes

Select this model when a high-current, dual-edge connection is required for thick PCBs. The 3.96 mm pitch offers robust spacing for power and ground traces compared to finer pitches. Consider the panel mount or free-hanging installation style based on chassis design. Verify compatibility with mating cards that utilize non-specified dual-edge profiles. The gold plating thickness ensures durability for repeated insertions if applicable.

Edgeboard Connectors Part Context

This component belongs to the EDAC 305 Series, which provides standardized card edge connectors for rack and panel applications. The series is known for accepting polarizing keys for alignment. Similar models include 305-048-500-201 and 305-048-520-578, differing primarily in mounting style and flange configuration. The 305 series is widely used in rugged environments requiring reliable electrical connections.

Edgeboard Connectors Replacement Considerations

Direct substitutes within the same series include part numbers such as 305-048-500-201 and 305-048-520-578. These alternatives share identical electrical specifications and pin counts but may differ in mounting hardware or flange orientation. Always verify mechanical dimensions against the original design before substitution.
