305-026-500-204

Edgeboard Connectors Overview

The EDAC Inc. 305-026-500-204 is a standard card edge connector featuring 26 positions in a dual-row configuration. It utilizes a 3.96 mm (0.156 inch) pitch and is designed for PCB thicknesses ranging from 1.37 mm to 1.78 mm. The component employs gold-plated copper alloy contacts with a half-beam termination type, ensuring reliable signal transmission. Rated for 5 A current, it operates within a temperature range of -40°C to +105°C. The housing is constructed from green thermoplastic polyester, providing necessary insulation and durability for panel mount applications.

Edgeboard Connectors Feature Summary

• Dual-edge female contact design accommodates non-specified card edge boards
• Gold-plated half-beam terminals ensure secure mechanical retention and electrical conductivity
• Thermoplastic polyester housing provides thermal stability and high insulation resistance

Edgeboard Connectors Applications

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

Edgeboard Connectors Procurement Notes

Verify the specific suffix codes against official EDAC documentation to confirm exact plating thickness and flange characteristics. Ensure that the selected variant matches the required PCB thickness tolerance and mounting style. Cross-reference the manufacturer part number with authorized distributor catalogs to confirm current availability and compliance status before finalizing procurement orders.

Edgeboard Connectors Selection Notes

Select this connector when a dual-row interface with a 3.96 mm pitch is required for robust panel-mounted connections. Consider the 5 A current rating and wide operating temperature range for demanding environments. Verify compatibility with the target card edge board thickness and ensure the vertical installation angle aligns with the chassis design constraints.

Edgeboard Connectors Part Context

This component belongs to the EDAC 305 Series, a line of standard card edge connectors known for high reliability. The series offers various position counts and termination options, catering to diverse industrial and commercial electronic applications. The 305-026-500-204 specifically addresses needs for medium-density dual-row connections with durable metallic contacts.

Edgeboard Connectors Replacement Considerations

Direct substitutes include other EDAC 305 series variants with matching 26-position dual configurations, such as 305-026-521-204, provided pinout and mechanical dimensions are identical. Verify that alternative sources maintain the same 3.96 mm pitch and gold plating specifications to ensure functional interchangeability.
