302-026-256-201

Edgeboard Connectors Overview

The EDAC Inc. 302-026-256-201 is a standard card edge connector from the 302 series, designed for dual-edge board applications. It features 26 positions with a contact spacing of 0.050 inches (1.27mm). The connector utilizes gold flash plated contacts on a copper alloy substrate to ensure reliable signal transmission. The housing is constructed from black polyamide (PA66) and supports a card thickness range of 0.051 to 0.071 inches (1.30mm to 1.80mm). This component employs a straddle mount installation method with solder termination.

Edgeboard Connectors Feature Summary

• Dual-row configuration with 26 female positions for non-specified dual-edge cards
• Gold flash contact finish over copper alloy for enhanced conductivity and corrosion resistance
• Straddle mount design allowing secure attachment across the PCB edge
• Polyamide (PA66) insulation material rated for operation between -55°C and 85°C

Edgeboard Connectors Applications

• Industrial control systems requiring robust edge connections
• Medical interconnect solutions for diagnostic equipment
• General-purpose electronic assemblies utilizing dual-edge circuit boards

Edgeboard Connectors Procurement Notes

Verify the specific ordering suffix against the official EDAC datasheet to confirm contact plating and housing color specifications. Ensure that the procurement channel provides valid traceability documentation. Confirm that the received components match the 302 series designation and possess the correct 26-position count before integration into production lines.

Edgeboard Connectors Selection Notes

Select this component when a low-profile, high-density connection is required for dual-edge cards. The 1.27mm pitch allows for compact board layouts compared to larger spacing alternatives. Verify that the target PCB thickness falls within the specified 1.30mm to 1.80mm range to ensure proper mechanical engagement and electrical stability during operation.

Edgeboard Connectors Part Context

This part belongs to the EDAC 302 series, which specializes in standard card edge connectors. The series is characterized by its fine 0.050-inch pitch and versatile mounting options. The 302-026-256-201 variant specifically addresses applications needing a moderate pin count with durable gold-plated contacts, fitting within EDAC's broader portfolio of interconnect solutions for demanding environments.

Edgeboard Connectors Replacement Considerations

Consult the official EDAC 302 Series Ordering Guide for cross-referencing compatible parts. Substitutes must maintain the identical 26-position count, 1.27mm pitch, and dual-edge compatibility. Verify that any alternative component matches the straddle mount style and PA66 housing material to preserve mechanical fit and thermal performance.
