305-054-556-202

Edgeboard Connectors Overview

The EDAC Inc. 305-054-556-202 is a dual-edge female card edge connector designed for board-to-board interconnection. It features 54 positions arranged in two rows with a 0.156-inch (3.96mm) pitch. The contacts are made of copper alloy with a gold finish, rated for 5A continuous current and 1800VACrms insulation voltage. It supports PCB thicknesses between 1.37mm and 1.78mm and operates within a temperature range of -40°C to +105°C.

Edgeboard Connectors Feature Summary

• Accepts between-contact and in-contact polarizing keys for secure alignment
• Straddle mount installation style provides stable board edge connection
• Gold-plated half-beadlock contact type ensures reliable signal transmission

Edgeboard Connectors Applications

• Card extender applications requiring high pin counts
• Industrial control systems utilizing standard card edge interfaces
• Test and measurement equipment needing robust vertical mounting

Edgeboard Connectors Procurement Notes

Verify the specific suffix codes against the manufacturer's ordering guide to ensure correct termination and flange configurations. Confirm that the target PCB thickness falls within the specified 1.37mm to 1.78mm range before integration. Check RoHS compliance status if environmental regulations apply to your assembly process.

Edgeboard Connectors Selection Notes

Select this component when a 54-position dual-row interface is required with a 3.96mm spacing. Ensure the design accommodates the straddle mount footprint and allows space for polarizing keys if mechanical locking is necessary. Compare against the 305 series general specifications for thermal and electrical limits.

Edgeboard Connectors Part Context

This part belongs to the EDAC 305 Series, which offers various position counts and mounting styles for card edge applications. It shares common family characteristics such as thermoplastic polyester insulation and copper alloy contacts. The specific model number indicates the 54-position variant within this standardized connector lineup.

Edgeboard Connectors Replacement Considerations

Cross-reference with other 305-series variants like 305-050-556-202 or 305-054-556-278 for similar form factors. Verify that substitute parts match the exact pitch, row count, and mounting orientation to maintain mechanical compatibility.
