305-074-556-507

Edgeboard Connectors Overview

The EDAC Inc. 305-074-556-507 is a standard card edge connector from the 305 series, designed for panel mount applications with a vertical orientation. It features 74 positions arranged in a dual-row configuration with a 3.96 mm (0.156 inch) pitch. The connector supports a board thickness of 1.57 mm and utilizes gold-plated copper alloy contacts for reliable signal transmission. Rated for 5 A current, it employs a solder pin termination method. The insulator is constructed from thermoplastic material, ensuring stable performance across an operating temperature range of -40°C to +105°C.

Edgeboard Connectors Feature Summary

• Dual-row contact configuration provides high-density interconnection capabilities within a compact form factor.
• Gold-plated copper alloy contacts ensure durable electrical connectivity and resistance to corrosion.
• Thermoplastic insulator housing offers mechanical stability and thermal resilience for demanding environments.

Edgeboard Connectors Applications

• Industrial control systems requiring robust panel-mounted interfaces
• Telecommunications equipment utilizing standard card edge modules

Edgeboard Connectors Procurement Notes

Verify the specific ordering suffix against official EDAC documentation to confirm exact plating thickness, flange style, and termination variations. Ensure compatibility with the target PCB edge thickness of 1.57 mm before procurement. Cross-reference the part number with the latest manufacturer datasheet to confirm availability status and any regional distribution restrictions that may apply to this specific component variant.

Edgeboard Connectors Selection Notes

Select this component when a 74-position dual-row interface is required for panel-mounted installations. The 3.96 mm pitch dictates compatible card edge dimensions, so verify PCB design constraints accordingly. Consider the vertical mounting angle and solder pin termination for assembly workflow alignment. Evaluate the 5 A current rating against system power requirements to ensure adequate performance margins under operational loads.
