305-042-521-507

Edgeboard Connectors Overview

The EDAC Inc. 305-042-521-507 is a standard card edge connector from the 305 series, designed for panel mounting with vertical orientation. It features a dual female configuration with 42 positions arranged in two rows. The contact pitch is 0.156 inches (3.96 mm), and it accepts printed circuit boards with a nominal thickness of 0.062 inches (1.57 mm). Contacts are gold-plated copper alloy, rated for 5 A current. The insulator body is green thermoplastic polyester, operating within a temperature range of -40°C to +105°C.

Edgeboard Connectors Feature Summary

• Dual-row female contact configuration for reliable board insertion
• Gold-plated contacts ensure stable electrical performance
• Low-profile insulator body design for compact assembly
• Panel mount installation style with vertical orientation

Edgeboard Connectors Applications

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

Edgeboard Connectors Procurement Notes

Verify that the specific suffix codes match the required flange and termination specifications. Confirm RoHS compliance status through official manufacturer documentation before integration. Ensure the ordering part number aligns exactly with the dual-row, 42-position requirement to avoid mechanical incompatibility during panel assembly.

Edgeboard Connectors Selection Notes

Select this component when a 3.96 mm pitch dual-row connector is required for 1.57 mm thick PCBs. The vertical panel mount style suits applications needing direct chassis integration. Verify that the 5 A current rating meets the system's power distribution needs and that the operating temperature range covers the environmental conditions.

Edgeboard Connectors Part Context

This connector belongs to the EDAC 305 series, which provides standard card edge solutions. The series offers various position counts and termination options. The 305-042-521-507 specifically addresses high-density interconnect needs with its 42-position layout, balancing space efficiency with signal integrity in industrial environments.

Edgeboard Connectors Replacement Considerations

Direct substitutes within the same series include 305-038-521-507 and 305-050-521-507, differing only in position count. Cross-series replacements require verification of pitch and row spacing compatibility.
