305-022-555-502

Edgeboard Connectors Overview

The EDAC Inc. 305-022-555-502 is a standard card edge connector from the 305 series, designed for dual-edge female board connections. It features 22 positions with a 3.96 mm (0.156 inch) pitch and supports PCB thicknesses between 1.37 mm and 1.78 mm. The connector utilizes gold-plated copper alloy contacts with a 10.0 µin (0.25 µm) plating thickness and half-beam contact types. Rated for 5 A current, it operates within a temperature range of -40°C to +105°C. The housing is made of green thermoplastic polyester, ensuring compliance with RoHS3 standards.

Edgeboard Connectors Feature Summary

• Dual-edge female configuration for secure mating with non-specified double-sided circuit boards
• Gold-plated copper alloy half-beam contacts ensure reliable electrical conductivity and corrosion resistance
• Thermoplastic polyester insulation provides stable performance across a wide operating temperature range

Edgeboard Connectors Applications

• Industrial control system backplanes
• Telecommunications equipment interconnects
• Test and measurement instrument modules

Edgeboard Connectors Procurement Notes

Verify that the specific suffix matches the required pin count and termination style. Confirm RoHS3 compliance status through official manufacturer documentation before integration. Ensure the ordering part number aligns exactly with the specified 22-position dual-edge requirement to avoid compatibility issues in panel-mounted assemblies.

Edgeboard Connectors Selection Notes

Select this component when a vertical, panel-mount solution is required for double-sided cards. The 3.96 mm pitch accommodates standard board thicknesses up to 1.78 mm. Verify that the application environment remains within the -40°C to +105°C operational limits and that the 5 A current rating suffices for the signal lines.

Edgeboard Connectors Part Context

This part belongs to the EDAC 305 series of standard card edge connectors. The series offers various position counts and termination options for both single and double-sided applications. The 305 series is characterized by its robust mechanical design and consistent electrical performance for general-purpose industrial interconnect needs.

Edgeboard Connectors Replacement Considerations

Cross-reference with other EDAC 305 series variants such as 305-022-521-202 for similar specifications. Ensure any substitute maintains the same 3.96 mm pitch, 22-position count, and dual-edge female configuration to guarantee mechanical fit and electrical continuity.
