305-038-521-501

Edgeboard Connectors Overview

The EDAC Inc. 305-038-521-501 is a dual-edge female card edge connector from the 305 series, designed for panel installation. It features 38 positions with a 0.156-inch (3.96 mm) pitch and accepts board thicknesses of 0.054 to 0.070 inches (1.37 to 1.78 mm). The contacts are made of copper alloy with a gold plating finish, ensuring reliable conductivity. Rated for 5 A current, it operates within a temperature range of -40°C to +105°C. The housing is constructed from thermoplastic polyester, providing insulation resistance of 5 GOhms.

Edgeboard Connectors Feature Summary

• Gold-plated copper alloy contacts for corrosion resistance
• Thermoplastic polyester insulator for high dielectric strength
• Panel mount design with vertical orientation

Edgeboard Connectors Applications

• Industrial control system backplanes
• Telecommunications equipment interconnects
• Medical device circuit board connections
• Automotive electronic module interfaces

Edgeboard Connectors Procurement Notes

Verify the specific ordering suffix against the manufacturer's official 305 Series Ordering Guide to ensure correct flange and termination specifications. Confirm that the target PCB thickness falls within the 0.054 to 0.070 inch range. Check RoHS compliance status as required by project regulations. Ensure panel mounting hardware compatibility with the specified flange dimensions before finalizing procurement orders.

Edgeboard Connectors Selection Notes

Select this component when a robust, high-current connection is required for double-sided edge cards. The 3.96 mm pitch suits applications needing fewer pins but higher current capacity per contact. Verify that the operating environment stays within the -40°C to +105°C thermal limits. Consider the panel mount style if space constraints prevent through-hole or surface-only mounting solutions on the main chassis.

Edgeboard Connectors Part Context

This part belongs to the EDAC 305 series of standard card edge connectors, which are widely used in harsh environments. The series offers various position counts and termination styles. The 305-038 variant specifically provides a balance between pin density and mechanical stability, suitable for medium-density interconnect applications requiring durable metal-to-metal contact reliability.
