305-026-521-501

Edgeboard Connectors Overview

The EDAC Inc. 305-026-521-501 is a dual female card edge connector designed for board-to-board interconnection. It features 26 positions arranged in two rows with a 0.156-inch (3.96 mm) contact pitch. The connector utilizes gold-plated copper alloy contacts and a green thermoplastic polyester insulator. It supports PCB thicknesses ranging from 0.054 to 0.070 inches (1.37 to 1.78 mm). Rated for operation between -40°C and +105°C, it employs a half-beam contact type for secure mating.

• Half-beam contact design for secure board retention

Edgeboard Connectors Applications

• Industrial control systems
• Telecommunications equipment
• Computer peripheral interfaces
• Test and measurement instrumentation

Edgeboard Connectors Procurement Notes

Verify the specific ordering suffix against the manufacturer's official 305 Series Ordering Guide to ensure correct pin count, termination style, and plating specifications. Confirm that the target application requires the standard 0.156-inch pitch and compatible board thickness range before finalizing procurement orders.

Edgeboard Connectors Selection Notes

Select this component when a dual-row female connector is required for non-specified dual-edge cards. Ensure the host PCB layout accommodates the 3.96 mm pitch and that the mating card thickness falls within the specified 1.37 to 1.78 mm range for proper mechanical engagement.

Edgeboard Connectors Part Context

This part belongs to the EDAC 305 Series of standard card edge connectors. The series offers various position counts and termination options, all sharing a consistent 0.156-inch pitch. This specific model represents a mid-range position count variant within the broader family of edgeboard connectors.

Edgeboard Connectors Replacement Considerations

Compatible substitutes include other EDAC 305 series variants with matching 26-position dual-row configurations. Verify cross-compatibility by confirming identical pitch, contact type, and mounting style requirements.
