305-038-555-558

Edgeboard Connectors Overview

The EDAC Inc. 305-038-555-558 is a standard card edge connector from the 305 series, designed for panel mount applications with a vertical orientation. It features 38 positions arranged in a dual row configuration with a contact spacing of 0.156 inches (3.96 mm). The connector accepts printed circuit boards with a nominal thickness of 0.062 inches (1.57 mm) and utilizes gold-plated copper alloy contacts terminated via solder lugs. Rated for 5 A continuous current and 1800 VACrms dielectric strength, it operates within a temperature range of -40°C to +105°C.

Edgeboard Connectors Feature Summary

• Accepts between-contact and in-contact polarizing keys for secure board retention
• Features a low profile insulator body constructed from thermoplastic material
• Provides robust electrical performance with high voltage isolation capabilities

Edgeboard Connectors Applications

• Panel-mounted electronic assemblies requiring vertical interconnection
• Industrial control systems utilizing standardized card edge interfaces
• Equipment needing polarized keying for precise board alignment

Edgeboard Connectors Procurement Notes

Verify that the specific ordering suffix matches the required termination style and flange characteristics. Confirm compatibility with the target PCB thickness and polarizing key requirements before procurement. Ensure environmental compliance aligns with project specifications.

Edgeboard Connectors Selection Notes

Select this component when a vertical, panel-mount solution is required for double-sided edge cards. The 38-position count and 3.96 mm pitch suit moderate-density applications. Verify that the solder lug termination method fits the assembly process constraints.

Edgeboard Connectors Part Context

This part belongs to the EDAC 305 series of standard card edge connectors. The series offers various position counts and mounting styles, providing a modular approach to board-to-board or backplane connections. The 305-038-555-558 represents a specific configuration within this established family.

Edgeboard Connectors Replacement Considerations

Cross-reference with other EDAC 305 series variants sharing identical pin counts and mechanical dimensions. Verify that substitute parts maintain the same contact spacing, current rating, and polarizing key acceptance capabilities.
