Overview
The EDAC Inc. 306-022-520-104 is a standard card edge connector from the 306 Series, designed for dual-edge board insertion. It features 44 positions with a contact spacing of 0.156 inches (3.96 mm). The connector utilizes cantilever contacts made of copper alloy with gold plating to ensure reliable signal transmission. It accepts printed circuit boards with a nominal thickness of 0.062 inches (1.57 mm) and employs a flush mounting style for secure panel installation.
Feature Summary
- Dual-edge female connector design accommodating two-sided PCB insertion
- Gold-plated cantilever contacts for durable electrical connection
- Flush mounting configuration for stable panel integration
- Low-profile insulator body constructed from thermoplastic material
Applications
- Industrial control systems requiring robust interconnects
- Telecommunications equipment backplanes
- Test and measurement instrumentation modules
- Automotive electronic control units
Procurement Notes
Verify that the specific part number matches the required 44-position count and 3.96 mm pitch before ordering. Confirm that the target application supports dual-edge board insertion and flush mounting requirements. Ensure compatibility with the specified 1.57 mm PCB thickness to maintain proper mechanical engagement. Check regional availability as distribution status may vary by location.
Selection Notes
Select this component when a high-density dual-edge interface is necessary for vertical or flush panel applications. The 306 series offers a balance of current capacity and mechanical stability suitable for demanding environments. Consider the gold plating thickness if harsh operating conditions are anticipated. Evaluate the overall profile height against available chassis space constraints.
Part Context
This connector belongs to the EDAC 306 Series, which specializes in standard card edge solutions. The series provides various position counts and termination options to support diverse electronic assembly needs. The 306-022-520-104 variant specifically addresses applications requiring 44 connections with a standardized 0.156-inch grid.
Replacement Considerations
Cross-reference with other EDAC 306 series parts for alternative position counts. Verify pinout compatibility when substituting with similar connectors from different manufacturers. Ensure that any replacement maintains the same 3.96 mm contact spacing and 1.57 mm board thickness tolerance.
