345-112-556-278

Edgeboard Connectors Overview

The EDAC Inc. 345-112-556-278 is a standard card edge connector designed for high-density interconnect applications. It features 112 positions arranged in a dual-row configuration with a 0.100 inch (2.54 mm) pitch. The connector utilizes gold-plated copper alloy contacts to ensure reliable signal transmission and corrosion resistance. It supports a maximum current rating of 3 A and operates within a temperature range of -40°C to +105°C. The housing is constructed from thermoplastic polyester, providing mechanical stability and electrical insulation. This component is intended for through-hole mounting on printed circuit boards.

Edgeboard Connectors Procurement Notes

Verify the specific ordering suffix against the official EDAC datasheet to confirm pin count, plating thickness, and mounting style. Ensure compatibility with the target PCB layout and card edge thickness specifications before procurement. Cross-reference the manufacturer part number with authorized distributor catalogs to confirm current availability and authenticity.

Edgeboard Connectors Selection Notes

Select this connector when a dual-row interface is required for double-sided edge cards. Consider the 2.54 mm pitch and 112-position capacity for space-constrained designs needing high channel counts. Evaluate the through-hole termination method against available PCB real estate and assembly processes. Confirm that the 3 A current rating meets the electrical requirements of the application signals.
