305-038-521-212

Edgeboard Connectors Overview

The EDAC Inc. 305-038-521-212 is a standard card edge connector from the 305 series, designed for vertical panel mount applications. It features 38 positions with a 3.96 mm (0.156 inch) pitch and supports dual-edge female contacts. The connector utilizes gold-plated copper alloy terminals and a thermoplastic polyester housing. It accommodates board thicknesses of 1.37 mm to 1.78 mm and operates within a temperature range of -40°C to +105°C.

Edgeboard Connectors Feature Summary

• Dual-edge female contact configuration for secure card insertion
• Vertical panel mount installation style with solder pin termination
• Gold-plated copper alloy contacts for reliable conductivity
• Thermoplastic polyester insulation material for durability

Edgeboard Connectors Applications

• Industrial control system interconnects
• Telecommunications equipment backplanes
• Embedded computing module interfaces

Edgeboard Connectors Procurement Notes

Verify the specific suffix codes against official EDAC documentation to confirm plating thickness and flange characteristics. Ensure compatibility with target PCB thickness specifications before procurement. Confirm RoHS3 compliance status through current manufacturer datasheets. Validate that the selected variant matches the required panel mounting orientation and terminal type for the intended assembly process.

Edgeboard Connectors Selection Notes

Select this component when a 38-position dual-edge interface is required with a 3.96 mm pitch. Consider the vertical panel mount form factor for space-constrained enclosures. Evaluate the operating temperature range against environmental conditions. Compare alternative series such as 315 or 357 if additional row terminations or different mounting options are necessary for the design.

Edgeboard Connectors Part Context

This part belongs to the EDAC 305 series of standard card edge connectors. The series offers various position counts and pitch options. The 305 series typically features thermoplastic polyester housings and gold-plated contacts. It is distinct from the 396 series which uses a 3.18 mm pitch and the 357 series which may have different flange configurations.

Edgeboard Connectors Replacement Considerations

Direct substitutes include other EDAC 305 series variants with matching 38 positions and 3.96 mm pitch. Cross-reference part numbers like 305-038-520-268 for similar specifications. Verify mechanical dimensions and electrical ratings before substitution.
