305-034-556-501

Edgeboard Connectors Overview

The EDAC Inc. 305-034-556-501 is a dual-edge female card edge connector from the 305 series, designed for board-to-board or backplane interconnections. It features 34 positions with a 0.156-inch (3.96mm) contact spacing and two termination rows. The connector utilizes gold-plated copper alloy contacts with a half-bead contact type to ensure reliable signal transmission. It supports PCB thicknesses ranging from 0.054 to 0.070 inches (1.37mm to 1.78mm) and operates within a temperature range of -40°C to 105°C. The housing is made of green thermoplastic polyester, providing insulation and mechanical stability.

Edgeboard Connectors Feature Summary

• Dual-edge female configuration accepts non-specified dual-edge cards for versatile board integration
• Gold-plated copper alloy contacts provide corrosion resistance and stable electrical performance
• Thermoplastic polyester insulator body ensures durability and thermal stability across wide operating temperatures

Edgeboard Connectors Applications

• Industrial control systems requiring robust board-to-board connections
• Telecommunications equipment utilizing standard card edge interfaces
• Test and measurement devices needing reliable high-density interconnects

Edgeboard Connectors Procurement Notes

Verify the specific ordering suffix against the manufacturer's current 305 Series Ordering Guide to confirm compatibility with required polarizing keys and flange characteristics. Ensure that the target printed circuit board thickness falls within the specified acceptance range of 0.054 to 0.070 inches to guarantee proper mechanical engagement and electrical contact integrity during installation.

Edgeboard Connectors Selection Notes

Select this component when a dual-edge female connector with 34 positions and 0.156-inch spacing is required. Confirm that the application environment stays within the -40°C to 105°C operational temperature range. Verify that the mating card meets the non-specified dual-edge profile requirements and that the assembly process accommodates the solder pin termination method for secure mounting.

Edgeboard Connectors Part Context

This part belongs to the EDAC 305 series of standard card edge connectors, which are widely used in industrial and commercial electronics. The series offers various position counts and termination options, providing engineers with flexible solutions for connecting peripheral boards to main system backplanes. The 305-034-556-501 specifically addresses applications needing a moderate number of I/O points with reliable gold-plated contact performance.

Edgeboard Connectors Replacement Considerations

Consult the official EDAC 305 Series cross-reference documentation for verified substitute part numbers. Do not assume interchangeability based on similar pin counts or spacing alone, as differences in flange dimensions, row spacing, and polarizing key compatibility may affect mechanical fit and electrical safety.
