305-038-555-508

Edgeboard Connectors Overview

The EDAC Inc. 305-038-555-508 is a standard card edge connector from the 305 Series, designed for dual-row applications with 38 positions. It features a 3.96 mm pitch and accepts board thicknesses between 1.37 mm and 1.78 mm. The connector utilizes gold-plated copper alloy contacts with a half-beam termination style for reliable signal transmission. Rated for 5 A continuous current and 1800 VACrms insulation voltage, it operates within a temperature range of -40°C to +105°C. The housing is constructed from green thermoplastic polyester, ensuring durability in demanding environments.

Edgeboard Connectors Procurement Notes

Verify the specific suffix codes against official EDAC documentation to confirm exact flange and termination variations. Ensure compatibility with existing PCB layouts regarding row spacing and overall dimensions. Confirm RoHS compliance status through the manufacturer's latest environmental declarations before integration into regulated products.

Edgeboard Connectors Selection Notes

Select this component when a dual-row card edge interface with a 3.96 mm pitch is required. Consider the 5 A current rating and 1800 VACrms insulation voltage for appropriate electrical safety margins. Evaluate the vertical panel mount style against available space constraints and ensure the housing material meets thermal requirements for the operating environment.

Edgeboard Connectors Part Context

This part belongs to the EDAC 305 Series, which offers various mounting options and position counts. The series is characterized by its standardized 3.96 mm pitch and robust construction suitable for industrial applications. Similar parts in the series differ primarily in position count and specific mounting hardware configurations.

Edgeboard Connectors Replacement Considerations

Cross-reference with other EDAC 305 Series variants for alternative position counts or mounting styles. Verify that any substitute maintains the same 3.96 mm pitch and dual-row configuration to ensure mechanical fit.
