Overview
The EDAC Inc. 306-020-421-112 is a standard card edge connector receptacle from the 306 series. It features 40 positions with a 3.96 mm (0.156 inch) contact spacing arranged in a single centerline row. Designed for panel mount installation at a vertical angle, it accepts printed circuit boards with a nominal thickness of 1.57 mm (0.062 inch). The contacts are constructed from copper alloy with tin plating and are rated for 5 A current. The insulator body is made of green thermoplastic polyester.
Feature Summary
- Single centerline row configuration with 3.96 mm contact spacing
- Vertical panel mount design for secure board retention
- Accepts 1.57 mm nominal thickness PCBs
- Low profile insulator body construction
Applications
- Industrial control system interconnects
- Telecommunications equipment backplanes
- Test and measurement instrument modules
- Computing hardware expansion slots
Procurement Notes
Verify that the specific tin-plated variant matches the application requirements, as gold-plated versions exist within the same series. Confirm the single-row receptacle orientation aligns with the mating card edge design. Ensure the panel mounting holes correspond to the mechanical drawing specifications before finalizing the procurement order.
Selection Notes
Select this component when a low-profile, single-row connection is required for thicker 1.57 mm boards. The tin plating offers cost-effective conductivity suitable for general applications. Consider the 3.96 mm pitch constraints against available routing space on the mating assembly.
Part Context
This part belongs to the EDAC 306 series of standard card edge connectors. The series provides various position counts and termination options. The 306-020-421-112 specifically denotes the 40-position, tin-plated, single-row variant designed for robust panel-mounted connections.
Replacement Considerations
The 306-020-421-102 serves as a direct substitute if gold plating is preferred over tin while maintaining identical mechanical dimensions and electrical ratings.
