306-026-500-101

Overview

The EDAC Inc. 306-026-500-101 is a dual female card edge connector from the 306 series, designed for panel mount installation. It features 52 positions with a 0.156-inch (3.96mm) pitch across two rows. The contacts are cantilever type with gold plating, suitable for non-specified double-sided cards ranging from 0.054 to 0.070 inches in thickness. Insulation is provided by polyester thermoplastic, and the unit operates within a temperature range of -40°C to 105°C.

Feature Summary

• Dual female contact configuration for reliable connection with double-sided circuit boards
• Cantilever spring contact design ensures secure mating force and durability
• Gold-plated terminals provide corrosion resistance and stable electrical performance
• Panel mount construction with flange features for secure mechanical integration

Applications

• Industrial control systems requiring robust board-to-board connectivity
• Test and measurement equipment interfaces
• Telecommunications hardware modules
• Automotive electronic sub-systems

Procurement Notes

Verify the specific ordering suffix against the official EDAC 306 Series Ordering Guide to ensure correct flange and termination specifications. Confirm that the target application utilizes double-sided card edges compatible with the specified 0.156-inch pitch. Check current availability status as lead times may vary based on manufacturing schedules and regional distribution constraints.

Selection Notes

Select this component when a high-density 52-position interface is required with a standard 0.156-inch spacing. Ensure the host panel supports the specified mounting dimensions and that the PCB thickness falls within the 0.054 to 0.070-inch operational window. Consider the operating temperature range and environmental compliance requirements such as RoHS3 certification before finalizing the design.

Part Context

This part belongs to the EDAC 306 series of standard card edge connectors, which are characterized by their versatility in industrial applications. The series offers various position counts and termination options, all sharing a common 0.156-inch pitch architecture. This specific model represents a mid-range density option within the lineup, balancing connection capacity with physical footprint constraints.

Replacement Considerations

Direct substitutes include other EDAC 306 series variants with identical pitch and position count but different flange configurations, such as 306-026-520-101. Cross-brand replacements require careful verification of dimensional tolerances, contact material properties, and insulation ratings to maintain system integrity.
