305-080-555-204

Edgeboard Connectors Overview

The EDAC Inc. 305-080-555-204 is a standard card edge connector from the 305 series, designed for dual female connections with 80 positions arranged in two rows. It features a 3.96 mm (0.156 inch) pitch and utilizes gold-plated copper alloy contacts to ensure reliable signal transmission. The unit supports PCB thicknesses ranging from 1.37 mm to 1.78 mm and operates within a temperature range of -40°C to +105°C. Constructed with thermoplastic polyester insulation, it provides robust mechanical stability and electrical performance for industrial applications.

Edgeboard Connectors Feature Summary

• Dual female contact configuration ensures secure mating with double-sided card edges.
• Gold-plated copper alloy contacts provide durable conductivity and corrosion resistance.
• Thermoplastic polyester insulation offers stable dielectric properties across wide temperatures.

Edgeboard Connectors Applications

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

Edgeboard Connectors Procurement Notes

Verify that the specific suffix matches the required flange feature, as the 305-080-555-204 variant specifies flush mount, top opening, unthreaded design with a 3.96mm diameter. Confirm compatibility with target PCB thickness limits of 1.37mm to 1.78mm before ordering. Ensure environmental ratings meet operational requirements given the -40°C to +105°C range.

Edgeboard Connectors Selection Notes

Select this component when a dual-row, 80-position interface is necessary for double-sided cards. The 3.96mm pitch dictates board layout constraints. Consider the unthreaded flush mount requirement against panel mounting needs. Verify that the thermoplastic polyester housing meets chemical resistance standards for the intended environment compared to alternative insulating materials.
