305-056-555-204

Edgeboard Connectors Overview

The EDAC Inc. 305-056-555-204 is a standard card edge connector from the 305 series, designed for dual-edge board applications. It features 56 positions with a 3.96 mm (0.156 inch) pitch. The connector utilizes female contacts made of copper alloy with gold plating and employs a solder pin termination method. It supports panel mounting at a vertical angle and accommodates PCB thicknesses ranging from 1.37 mm to 1.78 mm. The housing is constructed from green thermoplastic polyester, ensuring durability across an operating temperature range of -40°C to +105°C.

Edgeboard Connectors Feature Summary

• Dual-edge female contact configuration for secure mating with double-sided card edges
• Gold-plated copper alloy contacts ensure reliable electrical conductivity and corrosion resistance
• Vertical panel mount design facilitates stable integration into chassis or enclosure systems
• Thermoplastic polyester insulation provides structural integrity within specified thermal limits

Edgeboard Connectors Applications

• Industrial control system backplanes requiring robust signal transmission
• Telecommunications equipment interface modules
• Test and measurement instrument internal circuit boards
• Automotive electronic control unit interconnects

Edgeboard Connectors Procurement Notes

Verify that the specific part number matches the required 56-position count and 3.96 mm pitch before ordering. Confirm compatibility with the target PCB thickness range of 1.37 mm to 1.78 mm to ensure proper mechanical fit. Check regional availability status as distribution may vary by location. Ensure storage conditions maintain component integrity prior to assembly.

Edgeboard Connectors Selection Notes

Choose this model when a dual-edge connector with high positional density is required for vertical panel installation. The 3.96 mm pitch suits applications needing wider spacing between signal lines compared to finer pitches. Gold plating is essential for environments demanding long-term reliability without oxidation issues. Verify that the thermoplastic housing material meets the thermal requirements of the operational environment.

Edgeboard Connectors Part Context

This component 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 mounting styles to accommodate different board sizes and connection needs. The 305-056 variant specifically addresses applications requiring a moderate-to-high number of connections in a compact vertical form factor.

Edgeboard Connectors Replacement Considerations

Direct substitutes within the same series include other 305-series models with identical pitch and mounting characteristics but differing position counts, such as 305-050-556-502 or 305-054-556-278. Cross-series replacements require verification of pitch, contact type, and mechanical dimensions.
