305-038-500-501

Edgeboard Connectors Overview

The EDAC Inc. 305-038-500-501 is a standard card edge connector designed for reliable signal transmission in electronic assemblies. This component features 38 positions with a pitch of 0.156 inches (3.96 mm). It is constructed with a thermoplastic polyester housing and utilizes gold-plated copper alloy contacts to ensure durability and low contact resistance. The connector supports a continuous current rating of 5 A and withstands 1800 VACrms dielectric voltage. Designed as a dual-edge female receptacle, it accommodates board thicknesses up to 1.57 mm and operates within a temperature range of -40°C to +105°C.

Edgeboard Connectors Feature Summary

• Dual-edge female configuration accepts between-contact and in-contact polarizing keys for secure alignment
• Gold-plated phosphor bronze contacts provide corrosion resistance and stable electrical performance
• Thermoplastic polyester housing offers mechanical stability and thermal endurance
• Vertical panel mount style facilitates direct integration into chassis or enclosure systems

Edgeboard Connectors Applications

• High-speed data handling modules requiring robust interconnects
• FPGA-based system configurations needing precise timing performance
• Industrial control systems demanding reliable signal transmission
• Electronic assemblies utilizing polarized card edge interfaces

Edgeboard Connectors Procurement Notes

Verify the specific ordering suffix matches the required contact plating and housing color specifications. Confirm that the dual-edge female design aligns with the target PCB card edge geometry. Ensure compatibility with existing polarizing key requirements if between-contact or in-contact keys are utilized. Cross-reference the 3.96 mm pitch against the mating connector standards to prevent mechanical mismatch during assembly.

Edgeboard Connectors Selection Notes

Select this component when a dual-edge female interface is required for high-reliability applications. The 5 A current rating and 1800 VACrms insulation support demanding power and signal environments. Consider the vertical mounting orientation for panel-integrated designs. Verify that the 38-position count meets the circuit density requirements without exceeding the available board space constraints.

Edgeboard Connectors Part Context

This part belongs to the EDAC 305 series of standard card edge connectors. The series is characterized by its use of thermoplastic polyester materials and gold-plated contacts. Similar models in the series vary by position count and mounting style but maintain consistent electrical ratings and pitch dimensions. The 305 series is engineered for industrial and commercial electronics requiring durable interconnect solutions.

Edgeboard Connectors Replacement Considerations

Direct substitutes include other EDAC 305 series connectors with matching 38-position counts and dual-edge female configurations. Verify that alternative parts maintain the 0.156-inch pitch and 5 A current rating. Ensure housing material and operating temperature ranges match the original specifications for environmental compatibility.
