305-040-556-501

Edgeboard Connectors Overview

The EDAC Inc. 305-040-556-501 is a standard card edge connector from the 305 series, designed for dual-row board-to-board or backplane connections. It features 40 positions with a 3.96 mm (0.156 inch) pitch and supports a maximum current rating of 5 A. The connector utilizes gold-plated copper alloy contacts with a semi-bellows contact type to ensure reliable signal transmission. It is constructed with a green thermoplastic insulator and operates within a temperature range of -40°C to +105°C.

Edgeboard Connectors Feature Summary

• Dual-row configuration providing 40 total connection points for high-density applications
• Gold-plated semi-bellows contacts on copper alloy substrates for durable electrical performance
• Thermoplastic housing material offering stability across a wide operational temperature spectrum

Edgeboard Connectors Applications

• Industrial control systems requiring robust card edge interfaces
• Telecommunications equipment utilizing standard board thicknesses
• Computing hardware modules needing secure dual-row connectivity

Edgeboard Connectors Procurement Notes

Verify the specific suffix code against the manufacturer's official ordering guide to confirm exact mounting style and termination type. Ensure compatibility with the target PCB trace width and spacing requirements. Confirm that the operating environment temperature falls within the specified -40°C to +105°C range before finalizing procurement decisions.

Edgeboard Connectors Selection Notes

Select this component when a dual-row interface with a 3.96 mm pitch is required. The 40-position count suits moderate density needs. Verify that the application does not require panel-mount lugs, as this specific part number typically denotes a version without them. Ensure the mating card thickness aligns with the connector's design specifications for proper insertion force.

Edgeboard Connectors Part Context

This component belongs to the EDAC 305 Series, which offers various mounting options and row configurations. The series is characterized by its 3.96 mm pitch and robust construction suitable for demanding environments. The 305-040-556-501 specifically represents a 40-position variant within this standardized lineup.

Edgeboard Connectors Replacement Considerations

Cross-reference with other 305-series variants such as 305-040-521-202 for differences in flange features or termination styles. Ensure any substitute maintains the same 3.96 mm pitch and dual-row layout to guarantee mechanical fit.
