Overview
The EDAC Inc. 306-035-420-104 is a standard card edge connector from the 306 series, designed for panel mount applications with a vertical orientation. It features a dual female configuration with 70 positions and a contact spacing of 0.156 inches (3.96 mm). The connector accepts printed circuit boards with a nominal thickness of 0.062 inches (1.57 mm), accommodating a range of 0.054 to 0.070 inches. The contacts are tin-plated copper alloy, and the insulator body is made of green thermoplastic polyester.
Feature Summary
- Dual edge female connector design with 70 positions
- Accepts PCBs with nominal 0.062 inch thickness
- Low profile insulator body construction
Applications
- Panel mounted electronic assemblies
- Industrial control systems
- Communication equipment backplanes
Procurement Notes
Verify the specific contact finish requirement, as datasheets indicate this part may feature tin plating rather than gold. Confirm that the 70-position count aligns with the target board design. Ensure the panel mounting style and vertical angle match the enclosure constraints before finalizing the order.
Selection Notes
Select this component when a high-density 70-position interface is required for dual-edge cards. The 3.96 mm pitch provides robust mechanical stability compared to finer pitches. Verify compatibility with the target PCB thickness range of 1.37 mm to 1.78 mm to ensure proper insertion force and contact retention.
Part Context
This part belongs to the EDAC 306 series of standard card edge connectors. The series offers various position counts and termination options. The 306-035-420-104 specifically denotes the 70-position variant with tin plating, distinguishing it from gold-plated counterparts in the same family.
Replacement Considerations
The 306-035-420-103 is a direct substitute within the same series, offering identical mechanical dimensions and 70 positions but featuring gold plating instead of tin. Ensure the application environment does not require the corrosion resistance provided by gold plating.
