302-052-221-201

Edgeboard Connectors Overview

The EDAC Inc. 302-052-221-201 is a standard card edge connector from the 302 series, designed for dual-edge non-specified card applications. It features 52 positions arranged in two rows with a 0.050-inch (1.27mm) contact spacing. The connector utilizes female copper alloy contacts with gold flash plating and employs a cantilever contact type for reliable engagement. It is intended for through-hole termination and board edge mounting. The housing is constructed from black polyamide (PA66), nylon 6/6, ensuring durability across an operating temperature range of -55°C to +85°C.

Edgeboard Connectors Feature Summary

• Dual-edge configuration with cantilever contact design for secure card insertion
• Gold flash plated copper alloy contacts ensure stable electrical performance
• Polyamide (PA66) insulation material provides thermal stability and mechanical strength

Edgeboard Connectors Applications

• Industrial control systems requiring robust interconnects
• Medical equipment signal transmission interfaces
• Telecommunications hardware backplane connections

Edgeboard Connectors Procurement Notes

Verify that the specific part number matches the required 52-position count and dual-edge specification before ordering. Confirm that the gold flash plating thickness meets the application's wear requirements. Ensure the PCB layout accommodates the 0.050-inch pitch and through-hole termination style. Check compatibility with the target card thickness range to guarantee proper mating force and contact retention during operation.

Edgeboard Connectors Selection Notes

Select this component when a high-density connection is needed within a narrow profile constraint. The 0.050-inch pitch allows for significant I/O density compared to larger spacing alternatives. The dual-edge design supports higher pin counts without increasing the connector footprint width. Consider the PA66 housing material if environmental resistance against heat and chemicals is required for the deployment scenario.

Edgeboard Connectors Part Context

This connector belongs to the EDAC 302 series, which specializes in standard card edge solutions. The series offers various position counts to suit different interface needs while maintaining consistent mechanical dimensions and electrical characteristics. The 302-052-221-201 variant specifically addresses applications requiring 52 channels with a compact form factor suitable for dense circuit board layouts.

Edgeboard Connectors Replacement Considerations

Direct substitutes include other EDAC 302 series connectors with matching 52 positions and dual-edge specifications. Verify that any alternative maintains the same 0.050-inch pitch and gold flash plating to ensure interchangeability. Cross-reference mechanical drawings to confirm identical mounting hole patterns and housing dimensions for seamless integration into existing designs.
