Overview
The EDAC Inc. 306-033-521-178 is a standard card edge connector from the 306 series, designed for panel mounting applications. It features a dual female configuration with 66 positions arranged in two rows. The connector utilizes a 0.156-inch (3.96 mm) contact spacing and accepts printed circuit boards with a thickness ranging from 0.054 to 0.070 inches (1.37 mm to 1.78 mm). Contacts are constructed from copper alloy with gold plating to ensure reliable signal transmission.
Feature Summary
- Dual-edge female contact configuration for secure board insertion
- Panel mount installation style with flanged design
- Gold-plated copper alloy contacts for conductivity
- Compatible with specified nominal PCB thickness range
Applications
- Industrial control system interconnections
- Communication equipment backplanes
- Medical device internal circuitry
- Energy management hardware modules
Procurement Notes
Verify the specific suffix codes against official EDAC documentation to confirm exact pin count and termination type. Ensure compatibility with target PCB thickness specifications before integration. Confirm RoHS compliance status through current manufacturer declarations. Cross-reference ordering guides for accurate lead times and availability constraints.
Selection Notes
Select this component when a high-density dual-edge connection is required for panel-mounted assemblies. The 3.96 mm pitch supports robust mechanical stability for industrial environments. Verify that the housing material and temperature ratings align with operational requirements. Consider the vertical orientation for space-constrained panel layouts.
Part Context
This part belongs to the EDAC 306 series of card edge connectors, which are engineered for general-purpose electronic interconnections. The series offers various position counts and termination options to accommodate diverse board designs. These connectors are widely utilized across multiple industries requiring reliable signal paths between modules and backplanes.
Replacement Considerations
Direct substitutes within the same series include parts with identical pitch and position counts but different suffixes indicating varied termination or housing colors. Verify mechanical dimensions and electrical ratings before substitution.
