305-022-556-578

Edgeboard Connectors Overview

The EDAC Inc. 305-022-556-578 is a standard card edge connector from the 305 series, designed for dual-edge PCBs. It features 22 positions with a 3.96 mm (0.156 inch) pitch and supports two rows of contacts. The connector utilizes gold-plated copper alloy terminals with a half-bead contact type for reliable signal transmission. It is rated for 5 A current and operates within a temperature range of -40°C to +105°C. The housing is made of green thermoplastic polyester, providing insulation resistance of 5 GOhms. Designed for panel mount installation, it accommodates board thicknesses between 1.37 mm and 1.78 mm.

Edgeboard Connectors Procurement Notes

Verify the specific suffix code against the manufacturer's ordering guide to confirm terminal style and insulator variations. Ensure compatibility with the target PCB edge thickness and mounting hole specifications. Cross-reference the RoHS status and material declarations with the latest official datasheet to meet regulatory requirements for the intended deployment environment.

Edgeboard Connectors Selection Notes

Select this component when a robust, high-current card edge interface is required for panel-mounted applications. The 3.96 mm pitch offers spacing suitable for higher voltage isolation compared to finer pitches. Consider the 22-position count and dual-row layout for dense signal routing needs. Verify that the operating temperature range meets the environmental conditions of the final assembly location.

Edgeboard Connectors Part Context

This part 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 termination options.
