305-022-556-504

Edgeboard Connectors Overview

The EDAC Inc. 305-022-556-504 is a standard card edge connector from the 305 series, designed for vertical panel mounting. It features 22 positions across two rows with a 3.96 mm (0.156 inch) pitch. The contacts are made of copper alloy with gold plating and utilize a solder pin termination type. The housing is constructed from green thermoplastic polyester. It supports board thicknesses between 1.37 mm and 1.78 mm and operates within a temperature range of -40°C to +105°C.

Edgeboard Connectors Feature Summary

• Dual-edge female contact configuration for non-specified card types
• Vertical panel mount style with flanged mounting holes
• Gold-plated semi-beehive contact type for reliable signal transmission

Edgeboard Connectors Applications

• Industrial control system interface connections
• Telecommunications equipment backplane interconnects
• Test and measurement instrument module docking

Edgeboard Connectors Procurement Notes

Verify the specific ordering suffix against the manufacturer's current datasheet to ensure compatibility with required board thickness and mounting hole dimensions. Confirm RoHS compliance status and lead time availability directly with authorized distributors, as supply chain conditions may vary by region and date.

Edgeboard Connectors Selection Notes

Select this component when a dual-row, 22-position connection is required for vertical panel installation. Ensure the mating card edge thickness falls within the specified 1.37 mm to 1.78 mm range. Consider the 3.96 mm pitch and gold contact finish for applications requiring robust electrical performance in industrial environments.

Edgeboard Connectors Part Context

This part belongs to the EDAC 305 series of standard card edge connectors. The series offers various position counts and mounting options, all sharing common design characteristics such as thermoplastic insulation and gold-plated copper alloy contacts. The 305 series is widely used in general-purpose electronic assemblies requiring secure, high-density interconnections.

Edgeboard Connectors Replacement Considerations

Compatible substitutes include other EDAC 305 series variants with matching 22 positions and 3.96 mm pitch, such as 305-022-556-202 or 305-022-556-278, provided they meet the same mechanical and electrical specifications.
