Overview
The EDAC Inc. 306-028-420-107 is a standard card edge connector from the 306 series, designed for panel mount applications with a vertical orientation. It features a dual female configuration with 56 positions and a contact spacing of 0.156 inches (3.96 mm). The connector accepts printed circuit boards with a nominal thickness of 0.062 inches (1.57 mm). Contacts are made of copper alloy with tin plating to ensure reliable signal transmission. The unit has a current rating of 5 A and an insulation resistance of 5 GOhms. The housing is constructed from thermoplastic polyester, providing durability in operating temperatures ranging from -40°C to +105°C.
Feature Summary
- Dual female contact configuration for secure board insertion
- Low profile insulator body design for space-constrained panels
- Accepts standard 0.062 inch nominal thickness PCBs
- Tin-plated copper alloy contacts for corrosion resistance
Applications
- Industrial control systems requiring robust panel connections
- Communication equipment interface modules
- Medical device internal board interconnects
- Energy sector instrumentation panels
Procurement Notes
Verify the specific ordering suffix against the manufacturer's official datasheet to confirm contact plating type and terminal termination style. Ensure the procurement specification matches the required PCB thickness tolerance of 0.062 inches. Confirm that the tin-plated variant aligns with the application's environmental requirements before finalizing the purchase order.
Selection Notes
Select this component when a dual-edge card edge connector with 56 positions is required for vertical panel mounting. The 3.96 mm pitch suits applications needing higher density without excessive height. Verify compatibility with the target PCB stack-up and ensure the 5 A current rating meets the circuit load demands. Consider the operating temperature range for extreme environment deployments.
Part Context
This part belongs to the EDAC 306 series of standard card edge connectors, which are widely used in industrial and commercial electronics. The series offers various position counts and termination styles. The 306-028-420-107 specifically utilizes a dual female header format, distinguishing it from single-row or male-contact variants within the same family.
Replacement Considerations
No public confirmed substitute part numbers are available in the provided documentation. Cross-reference with other EDAC 306 series parts only if pin count and pitch match exactly.
