Overview
The EDAC Inc. 306-033-420-178 is a standard card edge connector designed for panel mounting applications. It features a dual female configuration with 66 positions arranged in two rows of 33 contacts each. The connector utilizes a 3.96 mm (0.156 inch) contact spacing and accepts printed circuit boards with a nominal thickness of 1.57 mm (0.062 inch). Constructed with copper alloy contacts featuring gold plating, it ensures reliable electrical performance within a thermoplastic insulator body.
Feature Summary
- Dual female contact configuration providing 66 total connection points
- Accepts standard 1.57 mm nominal thickness printed circuit boards
- Gold-plated copper alloy contacts for corrosion resistance
- Panel mount installation style with vertical orientation
Applications
- Industrial control system interconnections
- Telecommunications equipment backplanes
- Test and measurement instrument interfaces
- Automotive electronics module connections
Procurement Notes
Verify the specific ordering suffix to ensure compatibility with required board thicknesses and contact configurations. Confirm that the gold plating specification meets the intended application's conductivity requirements. Check RoHS compliance status if environmental regulations apply to the final assembly. Ensure panel mounting hardware matches the connector's flange specifications for secure installation.
Selection Notes
Select this component when a dual-row card edge interface with 66 positions is required. The 3.96 mm pitch suits applications needing robust mechanical stability. Verify that the target PCB thickness aligns with the 1.57 mm design parameter. Consider the vertical panel mount style for space-constrained enclosures requiring direct board insertion.
Part Context
This part belongs to the EDAC 306 series of standard card edge connectors. The series offers various position counts and mounting styles. The 306-033-420-178 specifically addresses high-density connection needs with its 66-position layout. It complements other EDAC components by providing standardized interface solutions for modular electronic systems.
Replacement Considerations
Cross-reference with EDAC 306-033-420-107 for similar specifications. Verify pin count and pitch compatibility before substitution. Ensure mechanical dimensions match the existing enclosure constraints. Confirm electrical ratings remain sufficient for the replacement application.
