305-028-555-512

Edgeboard Connectors Overview

The EDAC Inc. 305-028-555-512 is a standard card edge connector from the 305 series, designed for dual-row applications with a 28-position configuration. It features a 3.96 mm (0.156 inch) pitch and accepts non-specified dual-edge cards. The unit utilizes gold-plated copper alloy contacts with a semi-bellows contact type to ensure reliable signal transmission. Rated for 5 A continuous current, it supports panel mount installation via straddle mounting. The housing is constructed from thermoplastic polyester, providing durability across an operating temperature range of -40°C to +105°C.

Edgeboard Connectors Feature Summary

• Dual-row configuration with 28 positions for high-density interconnects
• Semi-bellows contact type ensures secure mating with card edge conductors
• Gold-plated copper alloy contacts provide corrosion resistance and conductivity
• Straddle mount panel installation style offers stable mechanical support

Edgeboard Connectors Applications

• Industrial control system backplanes
• Telecommunications equipment interfaces
• Test and measurement instrument modules
• Automotive electronic control units

Edgeboard Connectors Procurement Notes

Verify that the specific part number matches the required 28-position count and dual-row layout before procurement. Confirm that the straddle mount flange dimensions align with the panel cutout specifications. Ensure the selected card edge board thickness falls within the acceptable tolerance range for the semi-bellows contacts. Check RoHS compliance status if environmental regulations apply to the final assembly. Validate that the 5 A current rating meets the electrical requirements of the target circuit design.

Edgeboard Connectors Selection Notes

Select this component when a dual-row connection is required for vertical panel integration. The 3.96 mm pitch is suitable for applications needing robust mechanical retention without soldering the card directly. Consider the gold plating for environments requiring long-term reliability against oxidation. The thermoplastic polyester housing provides necessary insulation properties for industrial settings. Ensure the application does not require single-row configurations or different mounting styles such as surface mount.

Edgeboard Connectors Part Context

This connector belongs to the EDAC 305 series, which specializes in standard card edge connectors for various industrial and commercial applications. The series offers multiple position counts and mounting options to accommodate diverse design needs. The 305-028-555-512 specifically addresses the need for a mid-range position count with dual-row capability. It complements other variants in the series that offer different row counts or mounting configurations.

Edgeboard Connectors Replacement Considerations

Direct substitutes within the EDAC 305 series include parts with identical pitch and row configurations but different position counts, such as 305-018-555-512 or 305-038-555-512, if pin count adjustments are permissible. Verify that any replacement maintains the same straddle mount flange dimensions and contact type to ensure mechanical compatibility.
