305-054-555-207

Edgeboard Connectors Overview

The EDAC Inc. 305-054-555-207 is a standard card edge connector from the 305 series, designed for dual-row applications with 54 positions. It features a 3.96 mm (0.156 inch) contact spacing and accommodates printed circuit boards with a nominal thickness of 1.57 mm (0.062 inch). The connector utilizes gold plating on the mating area and tin plating with nickel underplating on the tails. Rated for 5 amps current, it offers a maximum contact resistance of 10 milliohms and an insulation resistance of 5 GOhms. Operating temperatures range from -40°C to +105°C.

Edgeboard Connectors Feature Summary

• Dual-edge female configuration with half-bellows contact type for secure board retention
• Gold-plated mating surfaces ensure reliable electrical conductivity and corrosion resistance
• Low-profile thermoplastic insulator body supports vertical panel mounting
• Flange features include flush installation with top opening and no-thread design

Edgeboard Connectors Applications

• Industrial control system backplanes
• Telecommunications equipment interconnects
• Test and measurement instrument modules
• Automotive electronic control units

Edgeboard Connectors Procurement Notes

Verify the specific ordering suffix against the manufacturer's official 305 Series Ordering Guide to confirm exact plating specifications and flange characteristics. Ensure compatibility with the target PCB thickness of 1.57 mm nominal. Confirm that the dual-edge female configuration aligns with the system's mechanical interface requirements before procurement.

Edgeboard Connectors Selection Notes

Select this component when a high-density 54-position connection is required within a limited vertical profile. The 3.96 mm pitch allows for substantial current handling at 5 amps per contact. Consider the panel mount style and flange dimensions for chassis integration. Verify that the operating temperature range meets the environmental conditions of the intended deployment scenario.

Edgeboard Connectors Part Context

This part belongs to the EDAC 305 series of standard card edge connectors, which are engineered for robust performance in demanding environments. The series offers various position counts and mounting options, providing flexibility for diverse electronic assembly needs. The 305-054-555-207 specifically addresses applications requiring a dual-row interface with standardized spacing and durable contact materials.

Edgeboard Connectors Replacement Considerations

Compatible substitutes within the same series include parts with identical pitch and position counts, such as the 305-054-556-278 or 305-054-520-207, provided their specific flange and plating configurations match the design requirements.
