305-022-521-201

Edgeboard Connectors Overview

The EDAC Inc. 305-022-521-201 is a standard card edge connector from the 305 series, designed for panel mount applications. It features a dual female configuration with 22 positions and a contact spacing of 3.96 mm (0.156 inches). The connector utilizes solder pin termination and gold-plated copper alloy contacts to ensure reliable signal transmission. It supports a PCB thickness of 1.57 mm and operates within a temperature range of -40°C to +105°C. With a continuous current rating of 5 A and an insulation resistance of 5 GOhms, this vertical header provides robust connectivity for electronic assemblies requiring high durability.

Edgeboard Connectors Feature Summary

• Accepts between-contact and in-contact polarizing keys for secure positioning
• Features gold-plated copper alloy contacts for enhanced conductivity
• Designed for vertical panel mounting with solder pin termination

Edgeboard Connectors Applications

• Electronic assemblies requiring polarized card edge connections
• Industrial control panels needing durable interconnect solutions
• Equipment utilizing standardized 3.96 mm pitch card edges

Edgeboard Connectors Procurement Notes

Verify the specific ordering suffix against official EDAC documentation to confirm exact contact length and plating specifications. Ensure compatibility with the target PCB thickness of 1.57 mm before integration. Cross-reference the manufacturer part number with authorized distributor catalogs to confirm current availability status and lead times. Confirm that the selected variant meets all required environmental operating temperatures for the intended application environment.

Edgeboard Connectors Selection Notes

Select this component when a dual-row card edge connector with polarizing key capability is required. The 3.96 mm pitch suits applications needing wider spacing for higher voltage isolation or mechanical stability. Verify that the 5 A current rating aligns with the circuit load requirements. Consider the vertical panel mount style if space constraints dictate a non-horizontal orientation. Ensure the gold plating specification matches the corrosion resistance needs of the operating environment.

Edgeboard Connectors Part Context

This component belongs to the EDAC 305 series, which offers a comprehensive range of card edge connectors characterized by a 3.96 mm contact spacing. The series is engineered for reliability in demanding environments, featuring options for various position counts and termination styles. The 305-022-521-201 specifically addresses the need for a 22-position dual female interface with polarizing support, fitting into the broader portfolio of industrial-grade interconnect solutions provided by EDAC Inc.

Edgeboard Connectors Replacement Considerations

Compatible substitutes within the 305 series include variants with different position counts such as 305-012-521-201 or 305-038-521-201, provided the position count matches the design requirement. Other suffixes may offer alternative contact lengths or packaging but maintain the same electrical and mechanical form factor. Always verify that any replacement maintains the 3.96 mm pitch and polarizing key acceptance capabilities.
