305-026-521-201

Edgeboard Connectors Overview

The EDAC Inc. model 305-026-521-201 is a standard card edge connector from the 305 series, designed for dual-edge board applications. It features 26 positions with a contact pitch of 3.96 mm (0.156 inches). The connector supports a PCB thickness of 1.57 mm and utilizes gold-plated copper alloy contacts for reliable signal transmission. Rated for 5 A current, it employs a solder pin termination type and is housed in a green thermoplastic polyester insulator. This vertical header is intended for panel mount installation.

Edgeboard Connectors Feature Summary

• Dual-row female configuration for non-specified dual-edge cards
• Gold-plated copper alloy contacts ensure durable electrical connection
• Thermoplastic polyester housing provides structural stability

Edgeboard Connectors Applications

• Industrial control systems requiring robust interconnects
• Telecommunications equipment backplanes
• Test and measurement instrumentation modules

Edgeboard Connectors Procurement Notes

Verify the specific ordering suffix to confirm contact plating thickness and insulation color specifications. Ensure the target application accommodates the 3.96 mm pitch and 1.57 mm board thickness constraints. Confirm that the vertical panel mount style aligns with the mechanical enclosure design requirements before finalizing procurement.

Edgeboard Connectors Selection Notes

Select this component when a dual-edge card interface with a 3.96 mm pitch is required. The 26-position count suits moderate-density applications. Verify compatibility with the target PCB thickness of 1.57 mm. The 5 A rating supports general power and signal distribution needs within standard industrial operating temperature ranges.

Edgeboard Connectors Part Context

This part belongs to the EDAC 305 series of standard card edge connectors. The series offers various position counts and mounting styles. The 305-026-521-201 specifically addresses dual-edge connectivity needs with a fixed 26-position layout and vertical orientation, distinguishing it from single-row or straight-mount variants in the same family.

Edgeboard Connectors Replacement Considerations

Direct substitutes include EDAC 305-026-521-512 and 305-026-521-568, which share identical mechanical dimensions and electrical ratings but may differ in insulation color or specific plating details.
