305-044-555-502

Edgeboard Connectors Overview

The EDAC Inc. 305-044-555-502 is a standard card edge connector from the 305 series, designed for dual female contact configurations with 44 positions. It features a 3.96 mm (0.156 inch) pitch and accepts PCBs with 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 offers a 5 A continuous current rating. It supports panel mounting in a vertical orientation with solder lug termination.

Edgeboard Connectors Feature Summary

• Dual-row female contact configuration for non-specified dual-edge card connections
• Gold-plated copper alloy semi-beryllium contacts ensure reliable signal transmission
• Panel mount design with vertical orientation and solder lug termination
• Accepts between-contact and in-contact polarizing keys for secure positioning

Edgeboard Connectors Applications

• Industrial control system interface modules
• Telecommunications equipment backplanes
• Test and measurement instrument cards
• Automotive electronic control unit interfaces

Edgeboard Connectors Procurement Notes

Verify the specific position count and pitch against the target PCB footprint before ordering. Confirm that the mating card thickness falls within the specified 1.37 mm to 1.78 mm range. Ensure the selected variant matches the required panel mounting style and termination type. Cross-reference the RoHS compliance status if environmental regulations apply to the final assembly.

Edgeboard Connectors Selection Notes

Select this component when a high-density dual-row connection is required for thick PCBs. The 3.96 mm pitch provides robust mechanical stability compared to finer pitches. Consider the 5 A current rating for power distribution needs alongside signal lines. Verify compatibility with existing polarizing key systems if used in modular rack environments.

Edgeboard Connectors Part Context

This part belongs to the EDAC 305 Series of card edge connectors, which are engineered for durability in harsh environments. The series offers various position counts and mounting options, catering to diverse industrial and commercial applications. The 305-044-555-502 specifically addresses needs for 44-position dual-edge connections with standardized panel mounting capabilities.

Edgeboard Connectors Replacement Considerations

Direct substitutes within the same series include parts with identical pitch and row configuration but different position counts, such as 305-038-520-502 or 305-050-556-502. Verify that any replacement maintains the 3.96 mm pitch and compatible PCB thickness range to ensure mechanical fit.
