302-120-256-201

Edgeboard Connectors Overview

The EDAC Inc. 302-120-256-201 is a standard card edge connector from the 302 series, designed for dual-edge board applications. It features 120 positions with a 0.050" (1.27mm) contact spacing and accepts board thicknesses between 0.051" and 0.071" (1.30mm to 1.80mm). The connector utilizes female, cantilever contacts made of copper alloy with gold flash plating. It employs a solder termination method and mounts via a board edge, straddle style. The housing is constructed from black polyamide (PA66), supporting an operating temperature range of -55°C to 85°C.

Edgeboard Connectors Feature Summary

• Dual-edge configuration with 120 female cantilever contacts for secure signal transmission
• Straddle mount installation design compatible with specified PCB thickness ranges
• Gold flash plated copper alloy contacts ensuring reliable conductivity and corrosion resistance
• Black polyamide insulation providing structural stability across wide temperature extremes

Edgeboard Connectors Applications

• High-density electronic module interconnections
• Industrial control system backplanes
• Telecommunications equipment interfaces
• Automotive electronics assemblies

Edgeboard Connectors Procurement Notes

Verify the specific ordering suffix against official EDAC documentation to ensure correct contact type and mounting style. Confirm RoHS compliance status and moisture sensitivity level requirements prior to integration. Cross-reference the manufacturer part number with authorized distributor catalogs to validate authenticity and current production status. Ensure storage conditions align with lead-free soldering process recommendations.

Edgeboard Connectors Selection Notes

Select this component when high pin density is required within a compact footprint using a 1.27mm pitch. Evaluate mechanical constraints to confirm compatibility with the 0.051" to 0.071" board thickness specification. Assess thermal environment suitability given the -55°C to 85°C operational rating. Consider the straddle mount profile for appropriate clearance and alignment needs in the final assembly design.

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 and mounting configurations tailored for diverse industrial and commercial applications. Components in this family typically feature robust construction suitable for repeated mating cycles or fixed installations requiring long-term reliability.

Edgeboard Connectors Replacement Considerations

Direct substitutes include other EDAC 302 series variants with matching 120-position counts and identical 0.050" spacing. Verify that alternative parts maintain the same dual-edge female contact configuration and straddle mount specifications to ensure mechanical interchangeability.
