305-046-556-202

Edgeboard Connectors Overview

The EDAC Inc. 305-046-556-202 is a dual-edge female card edge connector designed for board-to-board applications. It features 46 positions with a contact spacing of 0.156 inches (3.96mm) and a row spacing of 0.140 inches (3.56mm). The connector accepts printed circuit boards with a nominal thickness of 0.062 inches (1.57mm). Constructed with copper alloy contacts featuring gold plating, it ensures reliable signal transmission. The insulator body is green thermoplastic polyester, rated for operation between -40°C and +105°C.

• Vertical header configurations

Edgeboard Connectors Procurement Notes

Verify the specific part number against official EDAC documentation to confirm pin count and spacing compatibility. Ensure the target PCB thickness matches the specified 0.062-inch nominal requirement. Confirm RoHS compliance status if required by project specifications before finalizing procurement orders.

Edgeboard Connectors Selection Notes

Select this component when a dual-row female connector with 0.156-inch pitch is required for vertical or panel mounting. Consider the 5A current rating and 1800VACrms insulation voltage for electrical safety margins. Verify that the low-profile housing fits within the available mechanical envelope of the assembly.

Edgeboard Connectors Part Context

This component belongs to the EDAC 305 series of standard card edge connectors. The series offers various position counts while maintaining consistent 0.156-inch spacing. These connectors are widely used in industrial and commercial electronics for robust edgeboard connections requiring solder termination.

Edgeboard Connectors Replacement Considerations

Compatible substitutes include other EDAC 305 series variants with matching 46-position dual-edge specifications. Ensure replacement parts maintain the same 0.156-inch pitch and 0.062-inch board thickness acceptance criteria.
