345-074-555-508

Edgeboard Connectors Overview

The EDAC Inc. 345-074-555-508 is a standard card edge connector featuring a .100 inch (2.54mm) pitch and 74 positions. It utilizes a dual female contact configuration with gold plating on copper alloy terminals rated for 3A current. The housing is constructed from thermoplastic polyester, supporting PCB thicknesses of 1.57mm. Designed for through-hole mounting, this component includes #4-40 unified threaded inserts for secure panel installation. It operates within a temperature range of -40°C to +105°C and offers an insulation resistance of 5 GOhms.

Edgeboard Connectors Feature Summary

• Dual female contact design ensures reliable signal transmission for single-row card edge applications.
• Thermoplastic polyester housing provides structural integrity and chemical resistance.
• Gold-plated copper alloy contacts maintain low contact resistance and corrosion protection.
• Integrated flanges with threaded inserts facilitate stable vertical panel mounting.

Edgeboard Connectors Applications

• Industrial control system backplanes
