302-110-321-201

Edgeboard Connectors Overview

The EDAC Inc. 302-110-321-201 is a dual-edge card edge connector from the 302 series, designed for board-to-board interconnection. It features 110 positions with female contacts arranged in two rows of 55 pins each. The connector utilizes a 0.050 inch (1.27mm) pitch and accepts non-specified cards with thicknesses ranging from 0.051 to 0.071 inches (1.30mm to 1.80mm). Contacts are made of copper alloy with gold plating and employ a cantilever spring design. The housing is black polyamide (PA66), rated for operation between -55°C and 85°C.

Edgeboard Connectors Feature Summary

• Dual-edge configuration with cantilever spring contacts for reliable mating
• Gold-plated copper alloy terminals ensure low contact resistance
• Polyamide (PA66) insulation provides thermal stability and durability

Edgeboard Connectors Applications

• Industrial control systems requiring high-density I/O
• Telecommunications equipment backplanes
• Consumer electronics modular interfaces

Edgeboard Connectors Procurement Notes

Verify that the target PCB layout accommodates the specific 0.050-inch pitch and dual-row termination requirements. Confirm that the mating card thickness falls within the specified 1.30mm to 1.80mm range to ensure proper mechanical engagement. Check RoHS3 compliance status if environmental regulations apply to the final assembly.

Edgeboard Connectors Selection Notes

Select this component when a high-pin-count, dual-sided connection is required on a single board edge. The 110-position count supports complex signal routing without occupying excessive lateral space. Consider the 0.050-inch pitch as a balance between density and manufacturability compared to finer pitches.

Edgeboard Connectors Part Context

This part belongs to the EDAC 302 Series, which specializes in standard pitch card edge connectors. The series offers various pin counts and mounting styles, making it suitable for general-purpose electronic applications where standardized dimensions and robust electrical performance are prioritized over specialized industrial ratings.

Edgeboard Connectors Replacement Considerations

Direct substitutes must match the 110-position count, 0.050-inch pitch, and dual-edge female configuration. Verify that alternative parts support the same card thickness tolerance and maintain comparable gold plating specifications for equivalent electrical reliability.
