302-052-256-201

Edgeboard Connectors Overview

The EDAC Inc. 302-052-256-201 is a standard card edge connector from the 302 series, designed for dual-edge non-specified cards. It features 52 positions with a contact spacing of 0.050 inches (1.27mm). The contacts are gold flash plated copper alloy with a cantilever termination type. The housing is black polyamide (PA66/nylon 6/6) without mounting lugs. It supports board thicknesses from 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-row configuration with 52 gold-plated cantilever contacts for reliable signal transmission
• Extender board tails facilitate surface mount soldering to the host PCB
• Black polyamide housing provides structural support without integrated mounting lugs

Edgeboard Connectors Applications

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

Edgeboard Connectors Procurement Notes

Verify the specific suffix codes against the manufacturer datasheet to ensure compatibility with required board thickness and termination styles. Confirm that the dual-edge card specification matches the target application requirements before procurement. Cross-reference the RoHS status and environmental compliance data with current project standards.

Edgeboard Connectors Selection Notes

Select this component when a high-pin-count interface with fine pitch is required. The 1.27mm spacing allows for dense routing on the mating card. Ensure the design accommodates the extender tail footprint for proper SMT assembly. Consider the lack of mounting lugs if mechanical stability during insertion is critical.

Edgeboard Connectors Part Context

This part belongs to the EDAC 302 series, which specializes in low-profile card edge connectors. The series offers various pin counts and spacing options to suit different density needs. The 302-052-256-201 represents a high-position variant within this family, utilizing standard materials for general-purpose industrial applications.

Edgeboard Connectors Replacement Considerations

Compatible substitutes include other EDAC 302 series parts with matching pin counts or spacing. Verify electrical ratings and mechanical dimensions before substituting with components from other manufacturers.
