305-020-520-207

Edgeboard Connectors Overview

The EDAC Inc. 305-020-520-207 is a standard card edge connector receptacle featuring 20 positions in a dual-row configuration. It utilizes a 3.96 mm (0.156 inch) contact spacing and accommodates printed circuit boards with a nominal thickness of 1.57 mm (0.062 inch). The component employs gold-plated copper alloy contacts for reliable signal transmission and supports a current rating of 5 A. Designed for PCB mount applications, it offers vertical orientation and operates within a temperature range of -40°C to +105°C.

Edgeboard Connectors Feature Summary

• Dual-edge female connector design compatible with double-sided card edge circuits
• Gold-plated copper alloy contacts ensure durable electrical performance
• Thermoplastic polyester insulator body provides structural stability

Edgeboard Connectors Applications

• Industrial control system interconnections
• Telecommunications equipment backplanes

Edgeboard Connectors Procurement Notes

Verify the specific suffix code against the manufacturer datasheet to confirm exact plating thickness and material specifications. Ensure compatibility with the target PCB board thickness of 1.57 mm before integration. Confirm that the dual-row header configuration aligns with the mechanical constraints of the assembly enclosure.

Edgeboard Connectors Selection Notes

Select this component when a low-profile dual-row interface is required for 1.57 mm thick circuit boards. The 3.96 mm pitch suits applications needing robust connections without excessive height. Verify that the 5 A current rating meets the power distribution requirements of the connected modules.

Edgeboard Connectors Part Context

This part belongs to the EDAC 305 series of standard card edge connectors. The series provides various position counts and mounting styles for diverse electronic assembly needs. The 305-020 variant specifically addresses requirements for moderate density connections in compact form factors.

Edgeboard Connectors Replacement Considerations

Cross-reference with EDAC part numbers sharing the same 3.96 mm pitch and 20-position dual-row layout. Verify identical 1.57 mm board thickness tolerance and gold plating specifications to maintain mechanical and electrical compatibility.
