305-072-555-501

Edgeboard Connectors Overview

The EDAC Inc. 305-072-555-501 is a standard card edge connector from the 305 series, designed for reliable signal transmission in electronic assemblies. This receptacle features 72 positions arranged in two rows with a 3.96 mm (0.156 inch) pitch. It utilizes gold-plated copper alloy contacts to ensure low contact resistance and durability. The unit supports a continuous current rating of 5 A and withstands 1800 VACrms dielectric voltage. Designed for PCB mount applications, it accommodates board thicknesses of 1.57 mm and operates within a temperature range of -40°C to +105°C.

Edgeboard Connectors Feature Summary

• Dual-row configuration providing 72 connection points for high-density circuit integration
• Gold-plated copper alloy contacts ensuring corrosion resistance and stable electrical performance
• Accepts between-contact and in-contact polarizing keys for secure mating alignment

Edgeboard Connectors Applications

• Industrial control systems requiring robust interconnect solutions
• Telecommunications equipment utilizing standard card edge modules
• Automotive electronics demanding high reliability under thermal stress

Edgeboard Connectors Procurement Notes

Verify that the specific ordering suffix matches the required termination style and keying configuration before purchase. Confirm that the receiving PCB layout aligns with the 3.96 mm pitch and 1.57 mm board thickness specifications. Ensure environmental conditions do not exceed the +105°C maximum operating temperature limit. Cross-reference the manufacturer datasheet for precise dimensional tolerances to guarantee mechanical fit within the assembly enclosure.

Edgeboard Connectors Selection Notes

Select this component when a dual-edge card interface with 72 positions is required. The 3.96 mm pitch suits applications needing wider spacing for higher voltage isolation. Gold plating is essential for environments prone to oxidation or frequent mating cycles. Consider the vertical mounting style if panel integration is necessary. Evaluate the 5 A current capacity against the total load requirements of the connected circuitry to prevent overheating during operation.

Edgeboard Connectors Part Context

This part belongs to the EDAC 305 series of standard card edge connectors, widely used in modular electronic designs. The series offers various position counts and termination options to accommodate diverse board architectures. As a receptacle type, it interfaces with corresponding plug-style card edge connectors.
