302-040-356-201

Edgeboard Connectors Overview

The EDAC Inc. 302-040-356-201 is a standard card edge connector from the 302 series, designed for dual-edge PCB applications. It features 40 positions with a female contact type and a 0.050-inch (1.27mm) pitch. The contacts are gold-plated copper alloy with a cantilever design, ensuring reliable signal transmission. The housing is black polyamide (PA66), supporting board thicknesses between 0.051 and 0.071 inches. Rated for -55°C to 85°C, it utilizes a solder termination method for secure panel or board edge mounting.

Edgeboard Connectors Feature Summary

• Dual-edge configuration accommodates non-specified card types for versatile integration
• Gold-plated cantilever contacts provide durable electrical connectivity
• Polyamide insulation ensures stability across wide temperature ranges

Edgeboard Connectors Applications

• Industrial control systems requiring robust interconnects
• Telecommunications equipment with high-density signal paths
• Medical devices needing reliable board-to-board connections
• Consumer electronics utilizing standard card edge interfaces

Edgeboard Connectors Procurement Notes

Verify the specific ordering suffix to confirm contact spacing and plating thickness requirements. Ensure compatibility with the target PCB thickness range of 0.051 to 0.071 inches. Confirm RoHS3 compliance status if environmental regulations apply. Cross-reference the manufacturer part number against official distributor catalogs to avoid counterfeit components. Check for any updated datasheet revisions that may affect dimensional tolerances.

Edgeboard Connectors Selection Notes

Select this component when a 1.27mm pitch dual-edge connector is required for non-standard cards. Consider the cantilever contact style for ease of insertion and retention. Evaluate the PA66 material properties against thermal and mechanical stress conditions. Compare pin counts and row configurations with alternative series if space constraints exist. Verify termination method suitability for the assembly process.

Edgeboard Connectors Part Context

This part belongs to the EDAC 302 series, which specializes in low-profile card edge connectors. The series offers various pin counts and contact spacings tailored for compact electronic designs. The 302-040 variant specifically addresses higher density needs within the 1.27mm pitch family. It complements other EDAC products by providing standardized solutions for industrial and commercial sectors.

Edgeboard Connectors Replacement Considerations

Direct substitutes include other EDAC 302 series parts with matching pin counts and pitch. Verify equivalent specifications from manufacturers like NorComp if sourcing alternatives. Ensure identical contact geometry and insulation material for functional interchangeability.
