305-058-556-203

Edgeboard Connectors Overview

The EDAC Inc. 305-058-556-203 is a standard card edge connector from the 305 series, designed for dual-edge PCB insertion. It features 58 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 rated for 5 A current and employs a solder pin termination type. The housing is constructed from green thermoplastic material.

Edgeboard Connectors Feature Summary

• Dual-edge female connector design for secure board insertion
• Gold-plated copper alloy contacts ensure reliable signal transmission
• Low-profile insulator body accommodates space-constrained applications

Edgeboard Connectors Applications

• Industrial control systems requiring robust interconnects
• Telecommunications equipment backplanes
• Test and measurement instrumentation modules

Edgeboard Connectors Procurement Notes

Verify component authenticity through authorized EDAC distributors or certified suppliers. Confirm that the received part matches the specific 305-058-556-203 designation, including correct pin count and plating specifications. Ensure storage conditions comply with manufacturer guidelines to maintain contact integrity before assembly.

Edgeboard Connectors Selection Notes

Select this model when a dual-edge connection is required for 1.57 mm thick boards. The 3.96 mm pitch suits applications needing wider spacing than standard 2.54 mm connectors. Verify that the panel mount style aligns with the system enclosure design requirements.

Edgeboard Connectors Part Context

This component belongs to the EDAC 305 Series, a line of standard card edge connectors. The series offers various position counts and mounting styles. This specific variant provides a mid-range position count suitable for moderate density interconnect needs within industrial and commercial electronic assemblies.

Edgeboard Connectors Replacement Considerations

Direct substitutes must match the 58-position count, 3.96 mm pitch, and dual-edge configuration. Cross-referencing with other manufacturers requires verifying identical mechanical dimensions and electrical ratings to ensure functional compatibility in existing designs.
