305-022-555-204

Edgeboard Connectors Overview

The EDAC Inc. 305-022-555-204 is a standard card edge connector from the 305 series, designed for dual-edge board insertion. It features 22 positions with a contact spacing of 3.96 mm (0.156 inches) and a row spacing of 3.56 mm (0.140 inches). The connector accepts printed circuit boards with a nominal thickness of 1.57 mm (0.062 inches). Contacts are gold-plated copper alloy, rated for 5 A current. The housing is green thermoplastic polyester, supporting vertical panel mounting.

Edgeboard Connectors Feature Summary

• Gold-plated contacts ensure reliable conductivity
• Low-profile insulator body design
• Vertical panel mounting style

Edgeboard Connectors Applications

• Industrial control systems
• Telecommunications equipment
• Test and measurement instruments

Edgeboard Connectors Procurement Notes

Verify the specific suffix codes against the manufacturer datasheet to confirm exact plating thickness and material specifications. Ensure compatibility with the target PCB thickness of 1.57 mm before procurement. Confirm that the vertical panel mount style aligns with the mechanical enclosure requirements. Cross-reference the 22-position count with system interface needs.

Edgeboard Connectors Selection Notes

Select this component when a dual-row card edge interface is required with a 3.96 mm pitch. The 5 A rating supports moderate power applications. Verify that the vertical orientation fits the assembly constraints. Consider the thermoplastic polyester housing for environmental stability within the specified temperature range.

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 305-022 variant specifically provides a 22-position layout. It is engineered for robust connection between edgeboards and backplanes or chassis-mounted headers.

Edgeboard Connectors Replacement Considerations

Compatible substitutes within the 305 series include parts with identical pitch and position counts but different mounting styles or housing colors. Verify that any replacement maintains the 1.57 mm board thickness acceptance and 5 A current rating.
