305-028-555-501

Edgeboard Connectors Overview

The EDAC Inc. 305-028-555-501 is a standard card edge connector from the 305 series, designed for dual-edge board applications. It features 28 positions with a 0.156-inch (3.96 mm) pitch and supports two rows of contacts. The connector utilizes gold-plated copper alloy terminals with a half-bevel contact type for reliable signal transmission. It is rated for 5 A current and operates within a temperature range of -40°C to +105°C. The housing is made of green thermoplastic polyester, providing insulation resistance of 5 GOhms. Designed for panel mounting, it accommodates PCB thicknesses between 1.37 mm and 1.78 mm.

Edgeboard Connectors Procurement Notes

Verify component authenticity through authorized EDAC distributors or certified partners. Confirm RoHS compliance status prior to procurement, as environmental regulations vary by region. Ensure storage conditions maintain terminal integrity against oxidation. Cross-reference ordering suffixes to confirm exact pin count and plating specifications match project requirements before finalizing purchase orders.

Edgeboard Connectors Selection Notes

Select this model when dual-edge connectivity is required for boards up to 1.78 mm thick. The 3.96 mm pitch suits applications needing robust mechanical stability. Verify that the 5 A current rating meets circuit demands. Consider the vertical panel mount style for chassis integration. Ensure the operating temperature range aligns with the intended deployment environment's thermal profile.

Edgeboard Connectors Part Context

This component belongs to EDAC's 305 series of standard card edge connectors. The series offers various position counts and mounting styles. The 305-028 variant specifically provides 28 positions. It is part of a broader family including similar models like 305-014 and 305-050, differing primarily in contact count and specific housing configurations while maintaining consistent electrical characteristics.

Edgeboard Connectors Replacement Considerations

Direct substitutes include other EDAC 305 series parts with identical 28-position layouts and 3.96 mm pitch. Models such as 305-028-555-201 may serve as alternatives if different packaging or minor housing variations are acceptable. Always verify mechanical dimensions and electrical ratings before substitution.
