345-038-520-258

Edgeboard Connectors Overview

The EDAC Inc. 345-038-520-258 is a dual-row card edge connector designed for through-hole mounting. It features 38 contacts arranged in two rows with a 0.100-inch (2.54mm) pitch. The female terminals utilize a cantilever spring contact type with gold plating over a copper alloy base. The insulator is green thermoplastic polyester, rated for operation between -40°C and 105°C. It supports board thicknesses of 0.054 to 0.070 inches and includes guide set features for alignment.

Edgeboard Connectors Feature Summary

• Dual-row configuration with cantilever spring contacts for reliable signal transmission
• Gold-plated terminals ensure corrosion resistance and low contact impedance
• Integrated guide set mechanism provides precise board alignment during insertion
• Thermoplastic polyester insulator offers stability across wide temperature ranges

Edgeboard Connectors Applications

• Industrial control system backplanes
• Telecommunications equipment interconnects
• Medical device circuit board assemblies
• Automotive electronic module connections

Edgeboard Connectors Procurement Notes

Verify the specific ordering suffix against the official EDAC datasheet to confirm terminal style and flange options. Ensure compatibility with target PCB thickness specifications before procurement. Confirm RoHS compliance status if required by project regulations. Cross-reference the manufacturer part number with distributor catalogs to validate current availability and standard lead times.

Edgeboard Connectors Selection Notes

Select this component when a dual-row interface with integrated guiding features is required. The 0.100-inch pitch suits standard density applications. Verify that the cantilever contact type meets the mating cycle requirements. Ensure the through-hole termination method aligns with the assembly process. Check that the operating temperature range covers the intended environmental conditions.

Edgeboard Connectors Part Context

This part belongs to the EDAC 345 series of edgeboard connectors. The series provides various configurations for card edge applications. The 345-038 variant specifically addresses higher pin count needs within the dual-row format. It shares design principles with other parts in the family while offering distinct contact counts and mounting options.

Edgeboard Connectors Replacement Considerations

Direct substitutes include EDAC part numbers from the same 345 series with matching 38-pin dual-row specifications. Verify identical pitch, termination style, and guide set presence. Cross-check flange dimensions and mounting hole patterns for mechanical fit.
