Overview
The EDAC Inc. 306-027-421-112 is a standard card edge connector receptacle from the 306 series, designed for vertical panel mount applications. It features 54 positions with a 0.156-inch (3.96 mm) pitch and supports dual-edge card interfaces. The connector utilizes tin-plated copper alloy contacts and a green thermoplastic polyester housing. Rated for 5 A current, it accommodates board thicknesses between 0.054 and 0.070 inches. The unit employs solder pin termination for secure PCB attachment.
Feature Summary
- Vertical panel mount configuration for stable mechanical integration
- Dual-edge contact design compatible with double-sided circuit boards
- Tin-plated copper alloy contacts ensuring reliable signal transmission
- Thermoplastic polyester housing providing structural integrity
Applications
- Industrial control system interface connections
- Telecommunications equipment backplane interconnects
- Test and measurement instrument module mounting
Procurement Notes
Verify the specific ordering suffix to confirm contact finish and plating material, as variations exist within the 306 series. Ensure the selected part matches the required current rating and insulation resistance specifications for the target application environment. Cross-reference the datasheet for precise dimensional tolerances to guarantee compatibility with the intended card edge geometry.
Selection Notes
Select this component when a high-density 54-position connection is required in a vertical orientation. The 3.96 mm pitch suits applications needing robust spacing between terminals. Confirm that the dual-edge requirement aligns with the PCB design, as single-edge variants are available in the same series. Evaluate the thermal operating range against environmental conditions.
Part Context
This connector belongs to the EDAC 306 series of standard card edge connectors. The series offers various position counts and termination styles. The 306-027-421-112 specifically denotes a 54-position variant with tin plating. It is distinct from the 846 high-temperature series and other pitch variations found in the manufacturer's catalog.
Replacement Considerations
Direct substitutes include other 54-position, 3.96 mm pitch dual-edge connectors from EDAC with matching termination styles. Verify housing material and current ratings before swapping. Generic equivalents may lack the specific panel mount flange dimensions.
