Overview
The EDAC Inc. 306-021-420-112 is a dual-edge female card edge connector designed for panel and through-hole mounting. It features 42 positions with a 0.156-inch (3.96mm) contact spacing. The connector utilizes cantilever contacts made of copper alloy with a tin finish, ensuring reliable electrical performance. It accepts printed circuit boards with a nominal thickness of 0.062 inches (1.57mm). The insulator body is constructed from thermoplastic polyester, providing durability in demanding environments.
Feature Summary
- Dual-edge female configuration with cantilever contact type for secure board insertion
- Low-profile insulator body constructed from thermoplastic polyester material
- Supports both panel mount and through-hole installation methods
- Tin-plated copper alloy contacts ensure corrosion resistance
Applications
- Industrial control systems requiring robust card edge connections
- Telecommunications equipment utilizing standard PCB thicknesses
- Consumer electronics assemblies needing low-profile connectors
- Automotive electronic modules with specific mounting requirements
Procurement Notes
Verify the exact part number suffix to confirm contact plating and orientation specifications. Ensure compatibility with the target PCB thickness of 0.062 inches before procurement. Confirm that the tin finish meets the environmental requirements of the application. Check for RoHS compliance status if restricted substances are prohibited in the final assembly process.
Selection Notes
Select this component when a dual-edge female connector with 0.156-inch spacing is required. The 42-position count suits applications needing moderate I/O density. Consider the tin finish for general-purpose use rather than high-frequency or high-wear scenarios. Verify that the low-profile design fits within the available vertical clearance constraints of the enclosure.
Part Context
This connector belongs to the EDAC 306 series, which specializes in standard card edge solutions. The series offers various position counts and mounting styles to accommodate diverse PCB designs. The 306-021-420-112 variant specifically addresses needs for dual-edge connectivity with a single centerline row arrangement.
Replacement Considerations
Cross-reference with other EDAC 306 series parts for alternative position counts. Verify mechanical dimensions against existing board layouts before substituting. Ensure that any replacement maintains the same 0.156-inch pitch and 0.062-inch board thickness acceptance.
