305-044-521-502

Edgeboard Connectors Overview

The EDAC Inc. 305-044-521-502 is a standard card edge connector from the 305 series, designed for panel mount applications with a vertical orientation. It features a dual female configuration with 44 positions and a 0.156-inch (3.96 mm) pitch. The connector accepts non-specified dual-edge cards within a thickness range of 0.054 to 0.070 inches (1.37 to 1.78 mm). Contact plating is gold over a copper alloy base, providing a continuous current rating of 5 A. The housing is constructed from green thermoplastic polyester.

Edgeboard Connectors Feature Summary

• Dual female contact configuration for non-specified dual-edge board insertion
• Gold-plated copper alloy contacts ensure reliable signal transmission
• Panel mount design with vertical installation angle for secure integration
• Thermoplastic polyester insulation provides structural stability

Edgeboard Connectors Applications

• Industrial control systems requiring robust interconnects
• Telecommunications equipment backplanes
• Automotive electronic module connections
• Test and measurement instrumentation interfaces

Edgeboard Connectors Procurement Notes

Verify the specific suffix codes against official EDAC documentation to confirm exact pin count, plating thickness, and flange specifications. Ensure compatibility with target PCB card thickness limits. Confirm RoHS compliance status through manufacturer datasheets prior to final procurement decisions.

Edgeboard Connectors Selection Notes

Select this component when a high-density dual-edge interface is required for panel-mounted assemblies. The 3.96 mm pitch accommodates standard board widths while maintaining mechanical rigidity. Verify that the 5 A current rating meets system power distribution requirements and that the vertical form factor fits within enclosure constraints.

Edgeboard Connectors Part Context

This part belongs to the EDAC 305 series of standard card edge connectors, which are engineered for demanding industrial environments. The series offers various position counts and mounting styles, utilizing durable materials to withstand thermal cycling and mechanical stress during repeated insertions.

Edgeboard Connectors Replacement Considerations

Cross-reference with EDAC part numbers sharing the same 305 series prefix and identical 44-position dual-edge specifications. Verify matching pitch, current ratings, and mounting configurations before substitution.
