Overview
The EDAC Inc. 306-028-420-102 is a card edge connector from the 306 Series, designed for dual-edge board insertion. It features 56 positions with a 0.156-inch (3.96mm) centerline pitch. The connector utilizes a single central row configuration with female contacts that are tin-plated. The insulator body is green polyphenylene sulfide (PPS), providing a standard profile height of 0.460 inches (11.68mm). It employs straight solder pin termination for secure panel mounting.
Feature Summary
- Dual-edge receptacle design accommodates two-sided circuit boards
- Single central contact row ensures precise alignment
- Tin-plated female contacts provide reliable signal transmission
- Green PPS insulator offers standard mechanical stability
Applications
- Industrial control system interconnects
- Telecommunications equipment backplanes
- Consumer electronics module connections
- Medical device circuit board interfaces
Procurement Notes
Verify the specific ordering suffix to confirm contact plating and insulator color. Confirm that the 56-position count matches the dual-edge requirement. Ensure the 0.156-inch pitch aligns with the target PCB edge guide dimensions. Check RoHS compliance status against current regulatory requirements for the intended market.
Selection Notes
Select this component when a dual-edge connection is required for a 56-line interface. The 0.156-inch pitch suits standard board thicknesses. Tin plating is suitable for general-purpose applications without high corrosion exposure. The vertical orientation fits standard panel mount constraints.
Part Context
This part belongs to the EDAC 306 Series, which provides various design options for card edge interconnects. The series allows designers to tailor interconnect requirements through different position counts and configurations. It serves as a standard solution for connecting edge-board modules in electronic assemblies.
Replacement Considerations
Direct substitutes within the same series include variations like 306-028-421-104, which shares the 56-position count but differs in contact plating or housing specifications. Verify dimensional compatibility before substitution.
