305-058-556-212

Edgeboard Connectors Overview

The EDAC Inc. 305-058-556-212 is a standard card edge connector featuring 58 positions arranged in a dual-row configuration. It utilizes a contact spacing of 3.96 mm (0.156 inches) with a row spacing of 3.56 mm (0.140 inches). The component is designed to accept printed circuit boards with a nominal thickness of 1.57 mm (0.062 inches). Electrical specifications include a current rating of 5 A and an insulation resistance of 5 GOhms. The contacts are constructed from copper alloy with gold plating, housed in a thermoplastic polyester insulator body.

Edgeboard Connectors Feature Summary

• Dual-edge female connector design for straddle mounting on board edges
• Gold-plated copper alloy contacts ensure reliable signal transmission
• Low-profile insulator body accommodates standard 0.062-inch PCB thickness

Edgeboard Connectors Applications

• Card extender applications requiring dual-row connectivity
• Panel mount installations for vertical orientation
• Industrial control systems utilizing standard card edge interfaces

Edgeboard Connectors Procurement Notes

Verify the specific suffix codes against official EDAC documentation to confirm exact pin count and termination style. Ensure compatibility with the target PCB thickness of 1.57 mm before integration. Cross-reference the manufacturer part number with authorized distributor catalogs to confirm current availability status and regional distribution restrictions.

Edgeboard Connectors Selection Notes

Select this model when a dual-row interface with 58 positions is required for vertical panel mounting. The 3.96 mm pitch suits applications needing robust mechanical retention for 0.062-inch thick boards. Verify that the 5 A current rating meets the system's electrical load requirements and that the gold contact finish aligns with environmental durability needs.

Edgeboard Connectors Part Context

This component belongs to the EDAC 305 series of standard card edge connectors. The series offers various position counts and row configurations tailored for diverse electronic assembly needs. The 305-058-556-212 specifically addresses requirements for dual-row connectivity with precise dimensional tolerances for standard PCB formats.

Edgeboard Connectors Replacement Considerations

Compatible substitutes within the same series include parts with identical 58-position dual-row layouts and matching 3.96 mm pitch dimensions. Verify that alternative models maintain the same 1.57 mm board thickness acceptance and vertical mounting orientation to ensure mechanical interchangeability.
