Overview
The EDAC Inc. part number 306-029-421-108 is a standard card edge connector receptacle designed for vertical panel mount applications. It features a dual female configuration with 29 positions arranged in a single centerline row. The connector utilizes a 3.96 mm (0.156 inch) contact spacing and is rated for 5 A current. It accepts printed circuit boards with a nominal thickness of 1.57 mm (0.062 inch). The contacts are made of copper alloy with gold plating, while the insulator body is constructed from thermoplastic polyester.
Feature Summary
- Dual female contact configuration for secure card edge mating
- Vertical panel mount installation style with flush top flange
- Gold-plated copper alloy contacts for reliable conductivity
- Compatible with 1.57 mm nominal thickness PCBs
Applications
- Industrial control systems requiring robust card edge interfaces
- Communication equipment backplanes
- Medical device signal processing modules
- Energy management system interface cards
Procurement Notes
Verify the specific position count and contact configuration against the official EDAC datasheet to ensure compatibility with the target PCB design. Confirm that the panel mounting requirements align with the flush top flange feature. Check for any RoHS compliance documentation if required by the end-use application regulations. Ensure the operating environment temperature range matches the thermoplastic polyester insulation limits.
Selection Notes
Select this component when a vertical, panel-mounted solution is required for 29-position card edge connections. The 3.96 mm pitch is suitable for applications where board space allows for wider spacing compared to finer pitches. Consider the 5 A current rating for power or signal distribution needs. Verify that the PCB thickness of 1.57 mm is consistent with the assembly design to ensure proper mechanical engagement and electrical contact.
Part Context
This connector belongs to the EDAC 306 series, which focuses on standard card edge connectors. The series offers various position counts and configurations to support diverse electronic interconnection needs. The 306 series is characterized by its reliability in industrial and commercial environments, providing stable connections for plug-in cards and modules.
Replacement Considerations
Direct substitutes within the same series include parts like 306-029-421-104 or 306-029-500-102, though pin counts and configurations may vary. Always cross-reference the full datasheet specifications before substitution to ensure mechanical and electrical compatibility.
