305-038-521-507

Edgeboard Connectors Overview

The EDAC Inc. 305-038-521-507 is a standard card edge connector designed for vertical panel mounting applications. It features a dual female configuration with 38 positions arranged in two rows, providing a total of 38 contact points. The connector utilizes a 3.96 mm (0.156 inch) pitch and is compatible with non-specified dual-edge circuit boards having a thickness range of 1.37 mm to 1.78 mm. Contacts are constructed from copper alloy with gold plating and employ a half-beehive termination style for reliable signal transmission.

Edgeboard Connectors Feature Summary

• Vertical panel mount design with threaded flange inserts for secure installation
• Dual-edge female contacts with gold-plated copper alloy terminals
• Half-beehive termination style ensuring robust solder joint integrity

Edgeboard Connectors Applications

• Industrial control system interface connections
• Telecommunications equipment backplane interconnects
• Test and measurement instrument module docking

Edgeboard Connectors Procurement Notes

Verify the specific ordering suffix against the manufacturer's current datasheet to ensure compatibility with required flange thread specifications and board thickness tolerances. Confirm RoHS3 compliance status if environmental regulations apply to the final assembly. Cross-reference the pin count and row configuration with the target PCB layout to prevent mechanical interference during installation.

Edgeboard Connectors Selection Notes

Select this component when a vertical, panel-mount solution is required for dual-edge cards. Ensure the application environment falls within the specified operating temperature range of -40°C to +105°C. Verify that the mating card thickness aligns with the connector's acceptance range. Consider the threaded flange feature if vibration resistance or precise alignment is critical for the mechanical assembly.

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 to accommodate diverse electronic packaging needs. The 305-038-521-507 specifically addresses requirements for medium-density connections with secure panel mounting capabilities, distinguishing it from surface-mount or lower-profile alternatives within the broader product family.

Edgeboard Connectors Replacement Considerations

Direct substitutes within the same series include 305-038-521-502 and 305-038-520-502. Verify that alternative suffixes match the required flange threading and insulation material specifications before substitution.
