Overview
The EDAC Inc. 306-027-520-104 is a standard card edge connector from the 306 series, designed for panel mount applications. It features a vertical orientation with 27 positions and a contact spacing of 3.96 mm (0.156 inches). The connector utilizes gold-plated copper alloy contacts housed in a thermoplastic insulator, supporting a current rating of 5 A. It accommodates board thicknesses of 1.57 mm and operates within a temperature range of -40°C to +105°C. This component provides reliable electrical interconnection for dual-edge card applications.
Feature Summary
- Vertical panel mount design for secure installation
- Gold-plated copper alloy contacts for corrosion resistance
- Thermoplastic housing for high-temperature stability
Applications
- Industrial control system backplanes
- Telecommunications equipment interfaces
- Test and measurement instrument modules
Procurement Notes
Verify the specific pin count configuration against official datasheets, as part numbers in this series may vary by position count. Confirm RoHS compliance status and lead times directly with authorized distributors, as availability fluctuates. Ensure the selected variant matches the required board thickness and mounting style specifications for your assembly.
Selection Notes
Select this connector when a vertical, panel-mount solution is required for dual-edge cards. Verify that the 3.96 mm pitch aligns with the PCB edge guide dimensions. Consider the 5 A current rating and thermal limits for power distribution requirements. Ensure the thermoplastic material compatibility with soldering processes and environmental conditions.
Part Context
This component belongs to the EDAC 306 series of standard card edge connectors. The series offers various configurations including different row counts, termination styles, and contact spacings. The 306-027-520-104 specifically denotes a 27-position variant with gold plating and thermoplastic insulation, fitting into the broader category of industrial-grade interconnect solutions.
Replacement Considerations
Compatible substitutes include other EDAC 306 series variants with matching 3.96 mm pitch and vertical panel mount styles, such as the 306-025-520-107 or 307-022-527-104, provided the position count and termination type are verified against the original design requirements.
