302-026-356-201

Edgeboard Connectors Overview

The EDAC Inc. 302-026-356-201 is a standard card edge connector from the 302 series, designed for dual-edge board applications. It features 26 positions with a 0.050 inch (1.27mm) contact spacing. The connector utilizes female contacts with gold flash plating on copper alloy terminals. It employs a straddle mount installation method with solder termination. The housing is constructed from black polyamide (PA66/nylon 6/6) and supports card thicknesses ranging from 0.051 to 0.071 inches (1.30mm to 1.80mm).

Edgeboard Connectors Feature Summary

• Dual-row configuration with 26 female contacts for non-specified dual-edge cards.
• Straddle mount design allows secure attachment to the board edge without mounting lugs.
• Gold flash plated copper alloy contacts ensure reliable electrical conductivity.
• Polyamide insulation provides structural integrity within specified temperature ranges.

Edgeboard Connectors Applications

• Electronic modules requiring dual-edge card insertion
• Industrial control system interconnects
• Test and measurement equipment backplanes

Edgeboard Connectors Procurement Notes

Verify the specific ordering suffix against the manufacturer's current datasheet to confirm contact finish and housing variations. Ensure compatibility with the target PCB layout regarding straddle mount footprint and hole placement. Confirm that the card thickness falls within the 0.051 to 0.071 inch operational range before finalizing procurement decisions.

Edgeboard Connectors Selection Notes

Select this component when a low-profile, dual-edge connection is required with fine 1.27mm pitch. The straddle mount style offers stability without additional hardware. Consider the PA66 material properties and operating temperature limits of -55°C to 85°C for environmental suitability. Verify that the gold flash finish meets the necessary cycle life requirements for the application.

Edgeboard Connectors Part Context

This part belongs to the EDAC 302 series, which specializes in high-density card edge connectors. The series is characterized by its fine 0.050-inch spacing and versatile mounting options. The 302-026-356-201 specifically addresses needs for 26-position interfaces in compact electronic assemblies where space efficiency and reliable signal transmission are critical priorities.

Edgeboard Connectors Replacement Considerations

Cross-reference with other EDAC 302 series variants sharing identical pin counts and pitch. Verify mechanical dimensions and terminal type compatibility before substituting. Ensure any alternative maintains the same straddle mount configuration and gold contact finish specifications.
