305-082-556-507

Edgeboard Connectors Overview

The EDAC Inc. 305-082-556-507 is a standard card edge connector from the 305 series, designed for dual-edge board applications. It features 82 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). It utilizes gold-plated copper alloy contacts and a green thermoplastic insulator body. The unit supports a current rating of 5 A and operates within a temperature range of -40°C to +105°C.

Edgeboard Connectors Feature Summary

• Gold-plated copper alloy contacts ensure reliable electrical performance
• Panel mount installation style with vertical orientation

Edgeboard Connectors Applications

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

Edgeboard Connectors Procurement Notes

Verify the specific suffix codes against official EDAC documentation to confirm exact plating thickness, flange characteristics, and termination type before ordering. Ensure that the target PCB design accommodates the specified 1.57 mm thickness and 3.96 mm pitch. Confirm compliance with RoHS and REACH regulations as required by the end application environment. Cross-reference the manufacturer part number with distributor catalogs to avoid substitution errors due to similar series numbering.

Edgeboard Connectors Selection Notes

Select this component when a high-density dual-edge connection is required for thick PCBs. The 3.96 mm pitch allows for wider trace spacing compared to finer pitches, reducing manufacturing complexity. The panel mount style provides mechanical stability in chassis-based designs. Consider the 5 A current rating for power distribution needs alongside signal lines. Verify that the operating temperature range meets the environmental conditions of the intended deployment site.

Edgeboard Connectors Part Context

This connector belongs to the EDAC 305 Series, which offers various position counts and mounting options for card edge applications. The series is characterized by its standardized dimensions and reliable contact materials. Similar models in the series differ primarily in the number of positions and specific mounting hardware configurations while maintaining consistent electrical and mechanical interfaces.

Edgeboard Connectors Replacement Considerations

Direct substitutes must match the 82-position count, 3.96 mm pitch, and dual-row layout. Verify that alternative parts support the same 1.57 mm PCB thickness and panel mount style. Contact material and plating specifications should be equivalent to ensure compatibility.
