305-028-555-568

Edgeboard Connectors Overview

The EDAC Inc. 305-028-555-568 is a standard card edge connector header featuring 28 positions arranged in a dual-row configuration. It utilizes a 3.96 mm (0.156 inch) contact pitch with a 3.56 mm row spacing. Designed for vertical panel mounting, the unit accepts printed circuit boards with a nominal thickness of 1.57 mm. The contacts are constructed from copper alloy and feature gold plating to ensure reliable signal transmission. This component supports a continuous current rating of 5 A and operates within a temperature range of -40°C to +105°C.

Edgeboard Connectors Feature Summary

• Accepts between-contact and in-contact polarizing keys for secure board alignment
• Features a low-profile insulator body constructed from green thermoplastic material
• Utilizes half-beam contact type designed for dual-edge card insertion

Edgeboard Connectors Applications

• Industrial control system interconnects
• Telecommunications equipment backplanes
• Test and measurement instrument modules

Edgeboard Connectors Procurement Notes

Verify the specific suffix codes against official EDAC documentation to confirm exact pin count and termination style. Ensure that the ordering information matches the required dual-row configuration and panel mount orientation. Cross-reference the datasheet for insulation resistance values and voltage ratings before final procurement decisions.

Edgeboard Connectors Selection Notes

Select this model when a 28-position interface is required for double-sided card edge applications. The 3.96 mm pitch accommodates standard board thicknesses while maintaining high current capacity. Verify compatibility with existing polarizing key requirements and panel cutout dimensions prior to integration into the assembly design.

Edgeboard Connectors Part Context

This component belongs to the EDAC 305 series of standard card edge connectors. The series provides various position counts ranging from small configurations up to 86 contacts. These headers are engineered for robust mechanical stability and electrical performance in demanding industrial environments requiring reliable dual-row connections.

Edgeboard Connectors Replacement Considerations

Compatible substitutes include EDAC part numbers 305-022-555-568 and 305-030-555-568, which share identical pitch, mounting style, and series characteristics but differ in position count.
