305-066-555-258

Edgeboard Connectors Overview

The EDAC Inc. 305-066-555-258 is a standard card edge connector from the 305 series, designed for dual female termination with 66 positions. It features a contact spacing of 0.156 inches (3.96 mm) and a row spacing of 0.140 inches (3.56 mm). The connector accepts printed circuit boards with a nominal thickness of 0.062 inches (1.57 mm). Constructed with copper alloy contacts and gold plating, it utilizes a thermoplastic polyester insulator body.

Edgeboard Connectors Feature Summary

• Dual female termination configuration for reliable board insertion
• Low profile insulator body design for compact assembly
• Gold-plated copper alloy contacts ensure stable electrical performance
• Panel mount installation style with vertical orientation

Edgeboard Connectors Applications

• Industrial control systems requiring robust edge connections
• Telecommunications equipment interface modules
• Test and measurement instrument backplanes
• Computing hardware peripheral expansion slots

Edgeboard Connectors Procurement Notes

Verify the specific suffix codes against the manufacturer's ordering guide to confirm exact pin count, termination type, and insulation material properties. Ensure that the target PCB thickness aligns with the specified 0.062-inch nominal requirement to guarantee proper mechanical retention and electrical contact integrity during operation.

Edgeboard Connectors Selection Notes

Select this component when a high-density dual-row connection is required for thick PCBs. The 3.96 mm pitch offers reduced density compared to finer pitches but provides enhanced mechanical stability. Confirm compatibility with existing panel cutouts and mating card dimensions before finalizing the design integration.

Edgeboard Connectors Part Context

This part belongs to the EDAC 305 series of standard card edge connectors. The series is characterized by its durability and suitability for harsh environments. The 305-066-555-258 variant specifically addresses applications needing 66 signal paths with a standardized footprint compatible with broader industry mounting requirements.

Edgeboard Connectors Replacement Considerations

Consult the official EDAC 305 Series Ordering Guide for cross-referenced part numbers. Verify that any substitute maintains identical 0.156-inch spacing, 66-position count, and dual female termination characteristics to ensure functional equivalence.
