302-052-356-201

Edgeboard Connectors Overview

The EDAC Inc. 302-052-356-201 is a standard card edge connector from the 302 series, designed for dual-edge board applications. It features 52 positions with a 0.050-inch (1.27mm) contact spacing across two rows. The connector utilizes copper alloy contacts with gold plating and employs a cantilever spring contact type for reliable engagement. It supports PCB thicknesses ranging from 0.051 to 0.071 inches and operates within a temperature range of -55°C to 85°C.

Edgeboard Connectors Feature Summary

• Dual-edge female connector design with cantilever spring contacts for secure mating
• Gold-plated copper alloy contacts ensure low contact resistance and corrosion resistance
• Polyamide (PA66) insulation material provides thermal stability and mechanical strength
• Solder termination style facilitates through-hole mounting on target circuit boards

Edgeboard Connectors Applications

• Industrial control systems requiring robust peripheral connections
• Telecommunications equipment utilizing modular board architectures
• Automotive electronics interfaces demanding high reliability
• Test and measurement instrumentation with frequent board swapping

Edgeboard Connectors Procurement Notes

Verify the specific ordering suffix to confirm contact finish thickness and packaging configuration. Ensure compatibility with the target PCB stack-up and edge card dimensions. Confirm RoHS compliance status if required by project specifications. Cross-reference the manufacturer datasheet for precise dimensional tolerances before finalizing procurement orders.

Edgeboard Connectors Selection Notes

Select this component when a dual-edge connection with 1.27mm pitch is required. The 52-position count suits moderate-density interconnect needs. Verify that the host board thickness falls within the specified 0.051 to 0.071 inch range. Consider the operating temperature limits for environmental suitability in harsh industrial settings.

Edgeboard Connectors Part Context

This part belongs to the EDAC 302 series, which specializes in card edge connectors with 0.050-inch spacing. The series offers various position counts and termination styles. The 302-052-356-201 specifically addresses dual-edge applications, distinguishing it from single-edge variants within the same family. It represents a standardized solution for modular electronic assemblies.

Edgeboard Connectors Replacement Considerations

Direct substitutes include other EDAC 302 series parts with matching 52-position dual-edge configurations. Verify identical spacing, contact type, and termination method before substitution. Alternative manufacturers may offer compatible components if electrical and mechanical parameters align precisely with the original specification.
