Overview
The EDAC Inc. 306-024-420-158 is a standard card edge connector featuring 56 positions in a dual female configuration. It utilizes a 0.156-inch (3.96mm) contact spacing with a single centerline row design. The connector accepts printed circuit boards with a nominal thickness of 0.062 inches (1.57mm). Contact plating is specified as tin, and the insulator body is green. This component is designed for panel mount installation with a low-profile insulator body.
Feature Summary
- Dual edge female connector configuration providing 56 connection points
- Accepts PCBs with 0.062 inch nominal thickness for reliable mating
- Low profile insulator body construction for space-constrained applications
Applications
- Industrial control systems requiring robust card edge interfaces
- Telecommunications equipment board connections
- General purpose electronic assemblies utilizing standard card edge modules
Procurement Notes
Verify the specific ordering suffix to confirm contact plating and insulator color attributes. Ensure the selected variant matches the required PCB thickness tolerance of 0.062 inches. Confirm RoHS compliance status through official manufacturer documentation prior to procurement. Cross-reference the full part number against distributor catalogs to avoid mismatches in position count or tail type specifications.
Selection Notes
Select this connector when a dual-sided card edge interface with 56 positions is required. The 0.156-inch pitch accommodates standard board layouts. Tin plating offers cost-effective conductivity for general environments. Verify that the application does not require gold plating for high-cycle durability. Ensure the mounting style aligns with panel requirements.
Part Context
This component belongs to the EDAC 306 Series of standard card edge connectors. The series is characterized by a 0.156-inch contact spacing and versatile mounting options. The 306 series supports various position counts and tail configurations to meet diverse interconnect needs in industrial and commercial electronics.
Replacement Considerations
Direct substitutes within the same series include variants with different position counts such as 306-020-420-158 or 306-030-521-158. Ensure replacement parts maintain identical contact spacing and PCB thickness compatibility.
