305-020-521-568

Edgeboard Connectors Overview

The EDAC Inc. 305-020-521-568 is a standard card edge connector from the 305 series, designed for panel mount applications with a vertical orientation. It features 20 positions arranged in a dual row configuration with a 3.96 mm (0.156 inch) pitch. The connector utilizes gold-plated copper alloy contacts and accepts PCBs with a thickness of 1.57 mm. Rated for 5 A continuous current, it employs solder pin termination and includes flange features for secure mounting.

Edgeboard Connectors Feature Summary

• Dual-row female contact configuration for board-to-board or backplane interconnection
• Gold-plated copper alloy contacts ensure reliable signal transmission
• Panel mount design with vertical orientation and integrated flange
• Compatible with standard card edge PCBs of specified thickness

Edgeboard Connectors Applications

• Industrial control system backplanes
• Telecommunications equipment interconnects
• Test and measurement instrument modules
• Embedded computing hardware interfaces

Edgeboard Connectors Procurement Notes

Verify the specific ordering suffix against the manufacturer's official datasheet to confirm contact plating, housing material, and flange specifications. Ensure compatibility with the target PCB thickness and panel cutout dimensions. Confirm RoHS compliance status and environmental operating temperature range requirements before finalizing procurement orders.

Edgeboard Connectors Selection Notes

Select this component when a dual-row, panel-mount card edge connector with a 3.96 mm pitch is required. Verify that the application demands a 5 A current rating and vertical installation geometry. Ensure the mating card edge PCB thickness aligns with the 1.57 mm specification and that the gold-plated contact finish meets corrosion resistance needs.

Edgeboard Connectors Part Context

This part belongs to the EDAC 305 series of standard card edge connectors. The series offers various position counts and mounting styles. The 305-020-521-568 specifically denotes a 20-position dual-row variant with gold contacts and panel mount capabilities, distinct from single-row or PCB mount alternatives within the same family.

Edgeboard Connectors Replacement Considerations

Cross-reference with other EDAC 305 series parts sharing the 3.96 mm pitch and 20-position count. Verify identical flange dimensions and mounting hole patterns for direct mechanical substitution. Confirm electrical ratings and contact material match to ensure functional equivalence in the existing assembly.
