305-028-500-504

Edgeboard Connectors Overview

The EDAC Inc. 305-028-500-504 is a standard card edge connector from the 305 series, designed for panel mount applications with a vertical orientation. It features 28 positions arranged in two rows with a contact spacing of 3.96 mm (0.156 inches). The connector accepts printed circuit boards with a nominal thickness of 1.57 mm (.062 inches). Contacts are constructed from copper alloy and finished with gold plating to ensure reliable electrical performance. The unit provides a continuous current rating of 5 A and supports an operating temperature range from -40°C to +105°C.

Edgeboard Connectors Feature Summary

• Accepts between-contact and in-contact polarizing keys for secure board alignment
• Utilizes low profile insulator body construction
• Features solder lug termination type for robust mounting

Edgeboard Connectors Applications

• Panel-mounted electronic assemblies requiring dual-edge card connection

• Equipment interfaces demanding high insulation resistance and thermal stability

Edgeboard Connectors Procurement Notes

Verify that the specific part number matches the required position count and row configuration before ordering. Confirm compatibility with the target PCB thickness of 1.57 mm to ensure proper mechanical engagement. Check for any regional distribution restrictions or availability limitations associated with the manufacturer's supply chain at the time of purchase.

Edgeboard Connectors Selection Notes

Select this component when a dual-row card edge interface with 3.96 mm pitch is required for panel installation. Ensure the application environment falls within the specified -40°C to +105°C operational temperature range. Verify that the mating PCB design accommodates the necessary polarizing key slots and utilizes compatible contact materials.

Edgeboard Connectors Part Context

This connector belongs to the EDAC 305 series, which defines a family of standard card edge connectors characterized by .156 inch contact spacing. The series offers various position counts and termination options, all sharing common mechanical dimensions and material specifications for interchangeability within panel-mount designs.

Edgeboard Connectors Replacement Considerations

Compatible substitutes within the same series include the 305-028-520-504, which shares identical mechanical and electrical specifications. Other variants in the 305 series may serve as alternatives if position counts differ but form factors remain consistent.
