305-068-520-503

Edgeboard Connectors Overview

The EDAC Inc. 305-068-520-503 is a standard card edge connector from the 305 series, designed for dual-edge board applications. It features 68 positions arranged in two rows with a pitch of 3.96 mm (0.156 inches). The connector accepts PCBs with thicknesses ranging from 1.37 mm to 1.78 mm (0.054" to 0.070"). It utilizes gold-plated copper alloy contacts and offers a continuous current rating of 5 A. The housing is green thermoplastic, and it supports panel mount installation with through-hole solder termination.

Edgeboard Connectors Feature Summary

• Dual-row configuration supporting dual-edge card insertion
• Gold-plated copper alloy contacts for reliable signal transmission
• Compatible with between-contact and in-contact polarizing keys
• Panel mount design with vertical orientation

Edgeboard Connectors Applications

• Industrial control systems requiring robust interconnects
• Communication equipment backplanes
• Medical device circuit boards
• Energy management system interfaces

Edgeboard Connectors Procurement Notes

Verify the specific pin count and row configuration against the target PCB design before ordering. Confirm that the host board thickness falls within the specified range of 1.37 mm to 1.78 mm. Ensure compatibility with required polarizing key styles if mechanical locking is necessary. Check regional availability as distribution status may vary by location.

Edgeboard Connectors Selection Notes

Select this component when a high-density connection with 68 positions is required on a dual-edge board. The 3.96 mm pitch allows for broader trace spacing compared to finer pitches. Consider the 5 A current rating for power distribution needs. Verify that the panel mount style aligns with the enclosure design requirements.

Edgeboard Connectors Part Context

This part belongs to the EDAC 305 series of card edge connectors, which are characterized by their 3.96 mm pitch and dual-row architecture. The series provides various mounting options and position counts to accommodate different board sizes. The 305 series is widely used in industrial and commercial applications where reliable connectivity is critical.

Edgeboard Connectors Replacement Considerations

Direct substitutes must match the 68-position count, 3.96 mm pitch, and dual-row configuration. Verify that alternative parts support the same PCB thickness range and offer comparable current ratings. Ensure the replacement maintains the panel mount and through-hole termination style.
