305-082-555-258

Edgeboard Connectors Overview

The EDAC Inc. 305-082-555-258 is a standard card edge connector from the 305 series, designed for panel mount applications with a vertical orientation. It features 82 positions arranged in two rows 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 made of copper alloy with gold plating, providing a continuous current rating of 5 A and an insulation resistance of 5 GOhms. The operating temperature range spans from -40°C to +105°C.

Edgeboard Connectors Feature Summary

• Accepts between-contact and in-contact polarizing keys for secure board alignment
• Features a low-profile insulator body constructed from thermoplastic material
• Supports straddle mount installation for stable panel integration

Edgeboard Connectors Applications

• Card extender systems requiring dual-edge connectivity
• Industrial control panels utilizing standardized card edge interfaces
• Electronic assemblies needing polarized board insertion mechanisms

Edgeboard Connectors Procurement Notes

Verify component authenticity through authorized EDAC distributors or verified supply chain channels. Confirm that the specific part number matches the required 82-position configuration and gold-plated contact specifications. Ensure compliance with RoHS3 standards if environmental regulations apply to the final assembly. Check for any specific handling requirements related to the thermoplastic insulator body during storage and installation processes.

Edgeboard Connectors Selection Notes

Select this connector when a dual-row card edge interface with 3.96 mm pitch is required for panel-mounted applications. The 82-position count suits high-density signal routing needs within constrained vertical spaces. Consider the 5 A current rating and wide temperature tolerance for robust industrial environments. Verify compatibility with existing polarizing key systems to ensure proper board retention and electrical continuity.

Edgeboard Connectors Part Context

This component belongs to the EDAC 305 series of standard card edge connectors, which are engineered for reliable interconnection in various electronic systems. The series offers multiple position counts and mounting options to accommodate diverse design requirements. The 305-082-555-258 variant specifically addresses applications demanding high pin counts with precise board thickness acceptance, ensuring consistent performance across demanding operational conditions.

Edgeboard Connectors Replacement Considerations

Direct substitutes within the same series include parts with identical pitch and position counts but different mounting styles or contact finishes. Cross-series replacements may require mechanical adaptation due to variations in row spacing or insulator height. Verify that alternative components support the same polarizing key configurations and current ratings to maintain system integrity.
