302-022-221-201

Edgeboard Connectors Overview

The EDAC Inc. 302-022-221-201 is a standard card edge connector from the 302 series, designed for dual-edge board applications. It features 22 positions with a female contact type and a 0.050 inch (1.27mm) pitch. The connector utilizes gold-plated contacts on a copper alloy substrate, housed in black polyamide (PA66) insulation. It supports a card thickness range of 0.051 to 0.071 inches (1.30mm to 1.80mm) and operates within a temperature range of -55°C to 85°C.

Edgeboard Connectors Feature Summary

• Dual-edge configuration for secure connection to non-specified double-sided circuit boards
• Gold flash plating on copper alloy contacts ensures reliable signal transmission
• Polyamide (PA66) housing provides thermal stability and mechanical strength
• Vertical mounting style facilitates direct board-to-board or backplane integration

Edgeboard Connectors Applications

• Industrial control systems requiring robust interconnects
• Telecommunications equipment backplanes
• Test and measurement instrumentation modules
• Automotive electronics subsystems

Edgeboard Connectors Procurement Notes

Verify that the target PCB card thickness falls within the specified 1.30mm to 1.80mm range to ensure proper contact engagement. Confirm that the mating interface requires a dual-edge connector design rather than single-edge. Check for RoHS3 compliance requirements if operating in restricted substance environments. Ensure storage conditions maintain moisture sensitivity level 1 integrity before soldering.

Edgeboard Connectors Selection Notes

Select this component when a 1.27mm pitch is required for high-density routing on double-sided cards. The 302 series is appropriate for applications needing vertical orientation without flanges. Compare against single-edge variants if the board design only exposes contacts on one side. Consider the gold flash finish for general-purpose reliability rather than high-wipe-cycle environments requiring thicker plating.

Edgeboard Connectors Part Context

This part belongs to the EDAC 302 series, which specializes in low-profile card edge connectors. The series offers various position counts while maintaining a consistent 0.050-inch spacing. It is distinct from the 342 or 396 series, which feature different pitches and mounting styles such as through-hole with flanges. The 302 series focuses on compact, surface-mountable solutions for dense electronic assemblies.

Edgeboard Connectors FAQ

Is this connector compatible with single-edge cards?

No, the 302-022-221-201 is designed specifically for dual-edge cards where contacts are present on both sides of the board.

What is the maximum operating temperature?

The maximum operating temperature for this connector is 85°C.
