306-026-520-108

Overview

The EDAC Inc. part number 306-026-520-108 is a standard card edge connector belonging to the 306 Series. It features a dual female configuration with 52 positions arranged in two rows. The connector utilizes a centerline spacing of 0.156 inches (3.96 mm). The contacts are gold-plated copper alloy, providing reliable signal transmission. The insulator material is thermoplastic, colored green, with an insulator height of approximately 0.460 inches (11.68 mm). This component is designed for panel mount installation and supports vertical orientation relative to the mating card edge.

Feature Summary

• Dual edge female contact configuration for secure board retention
• Gold-plated copper alloy contacts ensure low resistance and corrosion resistance
• Thermoplastic insulator housing provides structural stability and electrical isolation
• Vertical panel mount design facilitates standardized chassis integration

Applications

• Industrial control system interface connections
• Telecommunications equipment backplane interconnects
• Consumer electronic device module attachment
• Medical instrumentation circuit board coupling

Procurement Notes

Verify the specific ordering suffix against the manufacturer's current datasheet to confirm exact pin count, plating thickness, and insulator height variations. Ensure compatibility with the target PCB card edge thickness and width specifications before procurement. Confirm RoHS compliance status if required by project regulations. Cross-reference the Mouser or DigiKey part numbers for accurate sourcing channels.

Selection Notes

Select this connector when a dual-row female card edge interface with 3.96 mm pitch is required. Evaluate the mechanical fit within the enclosure considering the 0.460 inch insulator height. Assess the thermal environment to ensure operation remains within specified limits. Compare against single-row alternatives if space constraints dictate a reduced profile. Verify that the gold plating meets the application's conductivity requirements.

Part Context

This component is part of EDAC's extensive portfolio of high-reliability interconnect solutions. The 306 Series represents a standard density card edge connector line known for robust mechanical performance. EDAC specializes in custom and standard connectors for demanding environments across various industries. This specific model serves as a critical link between rigid PCBs and flexible or semi-rigid card assemblies.

Replacement Considerations

Direct substitutes include EDAC part numbers 306-026-520-104 and 306-026-520-102, which share the same 52-position dual female configuration and 3.96 mm pitch. Verify that any alternative suffix matches the exact insulator height and mounting style requirements. Ensure the replacement maintains the same gold plating specification for equivalent electrical performance.
