305-066-556-258

Edgeboard Connectors Overview

The EDAC Inc. 305-066-556-258 is a standard card edge connector from the 305 series, designed for dual female contact configurations with 66 positions. It features a 3.96 mm (0.156 inch) pitch and supports board thicknesses ranging from 1.37 mm to 1.78 mm. The contacts are constructed from copper alloy with gold plating, rated for 5 A current. The housing is made of green thermoplastic polyester, providing an insulation resistance of 5 GOhms. Operating temperatures range from -40°C to +105°C.

Edgeboard Connectors Feature Summary

• Dual-row female contact configuration for secure card edge mating
• Gold-plated copper alloy contacts ensure reliable signal transmission
• Thermoplastic polyester housing provides high insulation resistance
• Panel mount vertical installation style with solder pin termination

Edgeboard Connectors Applications

• Industrial control system backplanes
• Telecommunications equipment interconnects

Edgeboard Connectors Procurement Notes

Verify the specific suffix code against the manufacturer's official ordering guide to confirm exact plating thickness and material specifications. Confirm panel mounting hole dimensions match the mechanical drawing before integration. Ensure the target PCB card thickness falls within the specified 1.37 mm to 1.78 mm range to guarantee proper contact engagement and electrical performance.

Edgeboard Connectors Selection Notes

Select this component when a 66-position dual-row interface is required with a 3.96 mm pitch. It is suitable for applications demanding vertical panel mounting and robust thermal stability up to 105°C. Consider the 5 A current rating and gold contact finish for environments requiring durable, low-resistance connections in industrial or telecom settings.

Edgeboard Connectors Part Context

This part belongs to the EDAC 305 Series, which offers various position counts and mounting styles for card edge applications. The series utilizes standardized thermoplastic housings and copper alloy contacts. This specific model represents a mid-range position count variant within the broader family of standard card edge connectors.

Edgeboard Connectors Replacement Considerations

Cross-reference with other EDAC 305 series variants such as 305-066-556-208 or 305-066-556-568 for alternative mounting or packaging options. Verify that any substitute maintains the identical 3.96 mm pitch and 66-position count to ensure mechanical compatibility.
