305-050-521-258

Edgeboard Connectors Overview

The EDAC Inc. 305-050-521-258 is a standard card edge connector from the 305 series, designed for panel mount applications. It features 50 positions arranged in two rows with a 0.156-inch (3.96 mm) pitch. The connector utilizes gold-plated copper alloy contacts and solder pin termination for secure electrical connections. It is rated for 5 A current and operates within a temperature range of -40°C to 105°C. The green thermoplastic polyester insulator supports dual-edge cards with thicknesses between 1.37 mm and 1.78 mm.

Edgeboard Connectors Feature Summary

• Dual-edge female connector design for robust board insertion
• Gold-plated contacts ensure reliable signal transmission
• Panel mount configuration with flange features for stability

Edgeboard Connectors Applications

• Industrial control systems requiring high-density interconnects
• Telecommunications equipment backplanes
• Test and measurement instrumentation boards

Edgeboard Connectors Procurement Notes

Verify the specific ordering suffix against official EDAC documentation to confirm contact plating thickness and insulator color specifications. Ensure compatibility with the target PCB panel thickness range of 1.37 mm to 1.78 mm. Confirm that the panel mount style aligns with the mechanical constraints of the enclosure design before finalizing procurement orders.

Edgeboard Connectors Selection Notes

Select this component when a high-current, dual-edge card interface is required for panel-mounted assemblies. The 3.96 mm pitch accommodates larger signal traces compared to finer pitches. Consider the 5 A rating for power distribution needs. Verify that the M3 threaded insert flange matches the mounting hardware available in the system 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 for diverse electronic applications. The 305-050 variant specifically provides a 50-position configuration suitable for moderate-density circuit boards. The series is known for its durable construction and reliable performance in demanding environments.

Edgeboard Connectors Replacement Considerations

Direct substitutes include other EDAC 305 series parts with identical 50-position, dual-edge, and 3.96 mm pitch specifications. Cross-reference mechanical drawings to ensure flange dimensions and mounting hole patterns match exactly. Verify that alternative parts maintain the same current rating and temperature range for equivalent performance.
