345-094-542-858

Edgeboard Connectors Overview

The EDAC Inc. 345-094-542-858 is a standard card edge connector featuring 94 positions arranged in two rows with a 2.54 mm pitch. It utilizes gold-plated copper contacts and a green thermoplastic polyester insulator. Designed for panel mounting at a right angle, it supports a maximum operating temperature of +105°C and a minimum of -40°C. The connector accommodates board thicknesses between 1.37 mm and 1.78 mm, ensuring reliable signal transmission in dual-edge applications.

Edgeboard Connectors Feature Summary

• Dual-edge female contact configuration for secure board insertion
• Gold-plated copper alloy contacts ensure low resistance and corrosion resistance
• Thermoplastic polyester housing provides thermal stability up to 105°C
• Panel mount right-angle design facilitates structured chassis integration

Edgeboard Connectors Applications

• Aerospace and defense systems requiring robust interconnects
• Medical equipment demanding reliable signal transmission
• Industrial control panels utilizing standardized card edge interfaces
• Telecommunications infrastructure hardware

Edgeboard Connectors Procurement Notes

Verify the specific ordering suffix against the manufacturer's official datasheet to confirm exact plating thickness, flange characteristics, and termination style. Ensure compatibility with the target PCB thickness range of 1.37 mm to 1.78 mm. Confirm RoHS compliance status through current distributor documentation before finalizing procurement specifications.

Edgeboard Connectors Selection Notes

Select this component when a high-density 94-position interface is required for dual-edge cards. The 2.54 mm pitch allows for standard spacing while maintaining a compact footprint. Consider the right-angle panel mount style for space-constrained enclosures where vertical clearance is limited but horizontal depth is available.

Edgeboard Connectors Part Context

This part belongs to the EDAC 345 series, a line of standard card edge connectors designed for general-purpose and specialized industrial applications. The series offers various position counts and mounting styles, providing engineers with flexible options for creating reliable electrical connections between circuit boards and backplanes or chassis-mounted headers.

Edgeboard Connectors Replacement Considerations

Direct substitutes include other EDAC 345 series parts with matching 94 positions and 2.54 mm pitch, such as 345-094-542-812, provided flange and termination details align. Cross-brand replacements require strict verification of pin count, pitch, board thickness tolerance, and mounting orientation to ensure mechanical and electrical compatibility.
