305-026-500-202

Edgeboard Connectors Overview

The EDAC Inc. 305-026-500-202 is a standard card edge connector from the 305 series, designed for reliable signal transmission in electronic assemblies. It features 26 positions with a contact spacing of 3.96 mm and a row spacing of 3.56 mm. The connector accepts printed circuit boards with a nominal thickness of 1.57 mm. Constructed with copper alloy contacts plated with gold, it ensures durability and low contact resistance. The housing is made of thermoplastic material, providing insulation and structural integrity.

Edgeboard Connectors Feature Summary

• Dual-edge design accommodates double-sided PCBs for increased connection density
• Gold-plated copper alloy contacts ensure corrosion resistance and stable electrical performance
• Low-profile insulator body reduces overall assembly height requirements
• Thermoplastic housing provides robust mechanical support and electrical insulation

Edgeboard Connectors Applications

• Industrial control systems requiring durable board-to-board connections
• Telecommunications equipment utilizing standard card edge interfaces
• Test and measurement instruments needing reliable signal pathways
• Automotive electronics modules with space-constrained layouts

Edgeboard Connectors Procurement Notes

Verify the specific ordering suffix to confirm contact plating and termination style. Ensure the selected variant matches the required PCB thickness and mounting configuration. Cross-reference the manufacturer datasheet for precise dimensional tolerances before integration. Confirm RoHS compliance status if restricted substances are a project constraint. Validate that the supplier provides original manufacturer documentation for quality assurance.

Edgeboard Connectors Selection Notes

Choose this connector when a dual-edge interface is necessary for high-density applications. The 3.96 mm pitch offers a balance between signal count and board space utilization. Gold plating is recommended for environments where oxidation resistance is critical. Consider the vertical or panel mount options available within the series based on enclosure constraints. Evaluate thermal operating ranges against the specified -40 C to +105 C limits.

Edgeboard Connectors Part Context

This component belongs to the EDAC 305 series of standard card edge connectors. The series offers various position counts and mounting styles to suit different design needs. Similar models include the 305-020-500-203 and 305-032-500-204, which share the same pitch and general construction but differ in pin count. The series is widely used in industrial and commercial electronics for its reliability and standardized dimensions.

Edgeboard Connectors Replacement Considerations

Direct substitutes within the EDAC 305 series include part numbers with identical pitch and row spacing but different position counts, such as 305-022-556-568 or 305-032-500-204. Verify that any replacement maintains the 1.57 mm PCB thickness compatibility. Ensure the termination type matches the existing assembly process. Cross-check insulation resistance and current ratings to guarantee equivalent performance levels.
