305-050-500-507

Edgeboard Connectors Overview

The EDAC Inc. 305-050-500-507 is a standard card edge connector from the 305 series, designed for dual-row board-to-board or backplane applications. It features 50 positions with a contact spacing of 0.156 inches (3.96 mm) and a row spacing of 0.140 inches (3.56 mm). The connector accepts printed circuit boards with a nominal thickness of 0.062 inches (1.57 mm). Constructed with copper alloy contacts plated with gold, it ensures reliable electrical performance. The insulator body is made of green thermoplastic polyester, offering durability in demanding environments.

Edgeboard Connectors Feature Summary

• Dual-row configuration providing 50 positions for high-density interconnects
• Gold-plated copper alloy contacts ensure corrosion resistance and low contact resistance
• Compatible with 0.062-inch nominal thickness PCBs for standard board integration
• Panel mount installation style supports secure vertical mounting

Edgeboard Connectors Applications

• Industrial control systems requiring robust panel-mounted connections
• Telecommunications equipment utilizing standard card edge interfaces
• Test and measurement devices needing reliable signal transmission
• Automotive electronics modules with specific form factor requirements

Edgeboard Connectors Procurement Notes

Verify the exact ordering suffix to confirm contact plating thickness and insulator color specifications. Ensure compatibility with the target PCB thickness of 0.062 inches before procurement. Confirm that the panel mount hole pattern matches the design layout. Check RoHS compliance status if required by project regulations. Validate that the dual-row female configuration aligns with the mating card edge requirements.

Edgeboard Connectors Selection Notes

Select this component when a dual-row interface with 0.156-inch spacing is required for 0.062-inch thick boards. The gold plating offers superior conductivity compared to tin variants. Consider the panel mount style for fixed installations rather than flexible cable applications. Verify that the 50-position count meets the signal and power line requirements of 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 row configurations to support diverse electronic assembly needs. The 305 series is known for its low-profile insulator body and reliable mechanical retention. It serves as a foundational interconnect solution for industrial and commercial electronic hardware designs.

Edgeboard Connectors Replacement Considerations

Direct substitutes within the same series include parts with identical spacing and position counts but different mounting styles or plating options. Cross-series replacements require matching the 0.156-inch pitch and 0.062-inch board thickness constraints. Verify that any alternative maintains the dual-row female contact type for proper mating.
