Overview
The EDAC Inc. 306-028-421-108 is a standard card edge connector receptacle designed for panel mount applications. It features a dual female configuration with 56 positions arranged in two rows, providing a total of 28 contacts per side. The connector utilizes a 3.96 mm (0.156 inch) pitch and accepts printed circuit boards with a nominal thickness of 1.57 mm. Electrical specifications include a current rating of 5 A and gold-plated copper alloy contacts to ensure reliable signal transmission.
Feature Summary
- Dual-edge female contact design accommodates double-sided PCBs
- Gold-plated copper alloy contacts provide corrosion resistance
- Thermoplastic polyester insulator body ensures structural stability
- Panel mount installation style with vertical orientation
Applications
- Industrial control systems requiring robust interconnects
- Telecommunications equipment board connections
- Automotive electronics assemblies
- Test and measurement instrumentation interfaces
Procurement Notes
Verify the specific ordering suffix against the manufacturer's official datasheet to confirm contact plating and material variations. Ensure compatibility with the target PCB thickness range of 1.37 mm to 1.78 mm. Confirm that the panel mounting requirements align with the connector's physical dimensions and flange specifications before finalizing procurement orders.
Selection Notes
Select this component when a high-current, dual-edge connection is required for thick PCBs. The 3.96 mm pitch suits applications where spacing constraints are less critical than mechanical durability. Gold plating is preferred for environments demanding long-term reliability without oxidation concerns. Verify that the vertical panel mount style fits within the available chassis space.
Part Context
This part belongs to the EDAC 306 series of standard card edge connectors. The series offers various position counts and configurations to support diverse electronic assembly needs. The 306 series is characterized by its robust construction and suitability for general-purpose industrial and commercial interconnect applications requiring secure board-to-panel connections.
Replacement Considerations
Direct substitutes within the same series include the 306-028-421-104 variant, which differs primarily in contact surface finish. Ensure that any replacement maintains the identical 56-position count, 3.96 mm pitch, and dual-edge female configuration to guarantee mechanical and electrical interchangeability.
