305-072-556-268

Edgeboard Connectors Overview

The EDAC Inc. 305-072-556-268 is a standard card edge connector from the 305 series, designed for dual-edge board applications. It features 72 positions with a 3.96 mm (0.156 inch) pitch and supports board thicknesses ranging from 1.37 mm to 1.78 mm. The connector utilizes gold-plated copper alloy contacts with a 0.25 µm plating thickness and employs a half-beam contact type for secure mating. It is rated for 5 A current at +105°C maximum operating temperature and offers 5 GOhms insulation resistance.

Edgeboard Connectors Feature Summary

• Dual-edge female connector design for non-specified card types
• Gold-plated copper alloy half-beam contacts ensure reliable signal transmission
• Thermoplastic polyester housing provides thermal stability and high insulation resistance

Edgeboard Connectors Applications

• Industrial control systems requiring robust panel-mounted interconnects
• Telecommunications equipment utilizing dual-edge PCB architectures
• Automotive electronics modules needing high-reliability vertical connections

Edgeboard Connectors Procurement Notes

Verify the specific suffix codes against the official EDAC ordering guide to confirm exact pin count, plating thickness, and flange specifications. Ensure compatibility with the target PCB thickness range of 1.37 mm to 1.78 mm before integration. Confirm RoHS3 compliance status through the manufacturer's latest documentation to meet regional regulatory requirements.

Edgeboard Connectors Selection Notes

Select this component when a dual-edge female connector with a 3.96 mm pitch is required for vertical or straight panel mounting. The 72-position configuration suits high-density interface needs. Consider the thermoplastic polyester material for environments demanding stable electrical properties across the -40°C to +105°C operating range.
