305-050-521-204

Edgeboard Connectors Overview

The EDAC Inc. 305-050-521-204 is a standard card edge connector from the 305 series, designed for dual-edge board applications. It features 50 positions with a 0.156-inch (3.96 mm) contact spacing and accepts printed circuit boards with a nominal thickness of 0.062 inches (1.57 mm). The component utilizes gold-plated copper alloy contacts and thermoplastic insulation, supporting a continuous current rating of 5 A.

Edgeboard Connectors Feature Summary

• Dual-row female configuration for non-specified dual-edge card connections
• Panel mount installation style with through-hole solder termination
• Low-profile insulator body constructed from thermoplastic material

Edgeboard Connectors Applications

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

Edgeboard Connectors Procurement Notes

Verify that the specific part number matches the required pin count and row configuration before ordering. Confirm that the host PCB design accommodates the specified panel mount footprint and solder lug termination style. Ensure compatibility with the target board thickness range to guarantee proper mechanical retention and electrical contact stability during operation.

Edgeboard Connectors Selection Notes

Select this connector when a dual-edge interface with 50 positions is required. The 0.156-inch pitch provides adequate spacing for high-voltage isolation needs. Consider the vertical mounting orientation and panel-mount form factor for chassis integration. Verify that the 5 A current rating meets the application's power distribution requirements.

Edgeboard Connectors Part Context

This component belongs to the EDAC 305 series of standard card edge connectors. The series offers various position counts and termination styles to support diverse electronic assembly needs. The 305-050-521-204 variant specifically addresses applications requiring robust dual-edge connectivity with standardized dimensions and reliable gold-plated contact surfaces.

Edgeboard Connectors Replacement Considerations

Cross-reference compatible parts within the same EDAC 305 series family. Verify identical pin counts, pitch dimensions, and mounting styles before substitution. Ensure that any alternative component maintains the same voltage and current ratings to preserve system safety and performance integrity.
