306-010-521-104

Edgeboard Connectors Overview

The EDAC Inc. 306-010-521-104 is a standard card edge connector from the 306 series, designed for vertical panel mount applications. It features a dual-edge female configuration with 20 positions arranged in two rows of ten. The connector utilizes a 3.96 mm (0.156 inch) pitch and accepts board thicknesses between 1.37 mm and 1.78 mm. Contacts are constructed from copper alloy with gold plating to ensure reliable signal transmission. The housing is made of green thermoplastic polyester, providing thermal stability within an operating temperature range of -40°C to +105°C.

Edgeboard Connectors Feature Summary

• Dual-edge female contact design accommodates double-sided circuit boards for increased I/O density.
• Vertical panel mount orientation with flange features for secure side-opening installation.
• Gold-plated copper alloy contacts provide corrosion resistance and low contact impedance.
• Thermoplastic polyester insulation offers high thermal endurance and mechanical durability.

Edgeboard Connectors Applications

• Industrial control systems requiring robust vertical interconnects
• Telecommunications equipment utilizing double-sided PCB architectures
• Automotive electronics modules demanding high thermal stability
• Test and measurement instrumentation interfaces

Edgeboard Connectors Procurement Notes

Verify that the target application supports dual-edge card insertion, as this component is not compatible with single-sided boards. Confirm that the printed circuit board thickness falls strictly within the 1.37 mm to 1.78 mm specification range to ensure proper contact engagement. Ensure the mounting environment allows for vertical panel access and accommodates the specified flange dimensions for secure installation.

Edgeboard Connectors Selection Notes

Select this model when a dual-row, double-sided connection is required for a 20-position interface. The 3.96 mm pitch distinguishes it from finer-pitch alternatives, making it suitable for higher-current or ruggedized environments. Consider the green housing color for visual identification if part of a larger assembly. Verify that the vertical mounting style aligns with the chassis design constraints and available panel space.

Edgeboard Connectors Part Context

This component belongs to the EDAC 306 series of standard card edge connectors, which are engineered for general-purpose industrial and commercial applications. The series offers various position counts and pitch options, but the 306-010-521-104 specifically addresses the need for dual-edge connectivity. It complements other EDAC products by providing a reliable solution for double-sided board integration in vertical configurations.

Edgeboard Connectors Replacement Considerations

Direct substitutes include other EDAC models within the 306 series that share the same 20-position dual-edge configuration and 3.96 mm pitch. Cross-manufacturer replacements require strict verification of pin count, pitch, board thickness tolerance, and mounting flange geometry to maintain mechanical and electrical compatibility.
