305-028-521-568

Edgeboard Connectors Overview

The EDAC Inc. 305-028-521-568 is a standard card edge connector from the 305 Series, designed for vertical panel mounting. It features 28 positions with a contact spacing of 3.96 mm (0.156 inches) and a row spacing of 3.56 mm (0.140 inches). The connector accepts printed circuit boards with a nominal thickness of 1.57 mm (0.062 inches). Contacts are gold-plated copper alloy with a solder pin termination type. The insulator body is green thermoplastic polyester, rated for operation between -40°C and +105°C.

Edgeboard Connectors Feature Summary

• Vertical panel mount design with low profile insulator body
• Gold-plated copper alloy contacts for reliable signal transmission
• Compatible with 0.062 inch nominal thickness PCBs
• Dual row configuration for high-density interconnect applications

Edgeboard Connectors Applications

• Industrial control systems requiring robust card edge interfaces
• Telecommunications equipment backplanes
• Test and measurement instrumentation modules
• Computer peripheral interface cards

Edgeboard Connectors Procurement Notes

Verify the specific suffix codes against the official EDAC ordering guide to ensure correct flange and termination options. Confirm that the required PCB thickness falls within the specified tolerance range for proper mechanical engagement. Check RoHS compliance status if restricted substances are mandated by project specifications. Ensure panel cutout dimensions align with the connector's physical envelope to prevent installation interference.

Edgeboard Connectors Selection Notes

Select this component when a vertical panel-mount solution is required for double-sided card edge connections. The 3.96 mm pitch suits applications needing wider spacing than standard 2.54 mm connectors. Verify that the 0.062 inch board thickness matches the target PCB design. Consider the gold plating for environments where corrosion resistance is critical. Evaluate the thermal rating against the operational temperature range of the host system.

Edgeboard Connectors Part Context

This part belongs to the EDAC 305 Series, which offers various configurations for card edge connectivity. The series provides options for different position counts, mounting styles, and termination types. The 305-028-521-568 specifically addresses needs for 28-position dual-row connections in panel-mounted scenarios. It complements other parts in the lineup by providing standardized dimensions and reliable electrical performance for industrial-grade hardware.

Edgeboard Connectors Replacement Considerations

Direct substitutes must match the 3.96 mm pitch, 28-position count, and vertical panel mount style. Verify compatibility with 0.062 inch PCB thickness. Cross-reference flange characteristics and termination methods before substitution. Generic equivalents may lack the specific mechanical tolerances or material ratings of the original EDAC component.
