306-026-421-103

Overview

The EDAC Inc. 306-026-421-103 is a standard card edge connector receptacle designed for vertical panel mount applications. It features a dual female configuration with 52 positions arranged in a single centerline row. The component utilizes a 3.96 mm (0.156 inch) contact spacing and is engineered to accept printed circuit boards with a nominal thickness of 1.57 mm (0.062 inch). The insulator body is constructed from thermoplastic polyester, providing a low-profile design suitable for space-constrained installations.

Feature Summary

• Dual female contact configuration for secure board retention
• Low profile insulator body construction
• Vertical mounting orientation for panel integration

Applications

• Industrial control system interconnects
• Telecommunications equipment backplanes
• Test and measurement instrumentation modules

Procurement Notes

Verify the specific datasheet version for the 306-026-421-103 to confirm current environmental compliance status and detailed mechanical dimensions. Ensure that the target PCB thickness aligns strictly with the 1.57 mm specification to guarantee proper contact engagement. Cross-reference the manufacturer's official documentation for any updates regarding material specifications or recommended mating cycles before finalizing procurement orders.

Selection Notes

Select this component when a high-density connection with 52 positions is required within a single row format. The 3.96 mm pitch offers a balance between signal density and manufacturing ease compared to finer pitches. Consider the vertical panel mount style if the design requires direct chassis integration rather than board-to-board stacking. Verify that the operating environment does not exceed the thermal limits of the thermoplastic polyester housing.

Part Context

This part belongs to the EDAC 306 series of standard card edge connectors, which are characterized by their robust construction and versatile design options. The series allows for various tailoring of interconnect requirements to meet specific designer needs. The 306 series is widely utilized in applications requiring reliable electrical connections between edge cards and system backplanes or panels.

Replacement Considerations

Direct substitutes must match the 52-position count, 3.96 mm pitch, and dual female configuration. Verify compatibility with 1.57 mm board thickness and vertical panel mount requirements. Consult the manufacturer's cross-reference guide for officially confirmed alternative part numbers within the same series or equivalent specifications.
