Overview
The EDAC Inc. 306-027-521-103 is a standard card edge connector featuring a dual female configuration with 54 positions. It utilizes a 0.156-inch (3.96 mm) contact spacing and accepts printed circuit boards with a nominal thickness of 0.062 inches (1.57 mm). The component employs gold-plated copper alloy contacts for reliable signal transmission. Designed for panel mounting, it operates within a temperature range of -40°C to +105°C and maintains an insulation resistance of 5 GOhms.
Feature Summary
- Dual female card edge interface designed for vertical panel mounting applications
- Gold-plated copper alloy contacts ensure durable electrical connectivity
- Flush mount flange feature with floating bobbin design for secure installation
Applications
- Industrial control system interconnects
- Telecommunications equipment backplanes
- Test and measurement instrument modules
Procurement Notes
Verify the specific ordering suffix against the manufacturer's official datasheet to confirm exact pin count, termination style, and flange specifications. Ensure compatibility with the target PCB thickness of 0.062 inches. Confirm that the required operating temperature range aligns with the component's rated limits of -40°C to +105°C before finalizing procurement decisions.
Selection Notes
Select this connector when a high-density 54-position interface is required for panel-mounted assemblies. The 0.156-inch pitch accommodates standard board layouts while the dual female design supports robust mating cycles. Consider the green thermoplastic insulation body and flush mount requirements during mechanical integration planning.
Part Context
This component belongs to the EDAC 306 series of standard card edge connectors. The series is characterized by its single centreline row configuration and low-profile insulator body. It is engineered for general-purpose electronic applications requiring reliable board-to-board or board-to-backplane connections in constrained spaces.
Replacement Considerations
Cross-reference part numbers such as 306-027-521-112 or 306-027-521-168 from the same manufacturer family. Verify that substitute parts maintain identical position counts, contact spacing, and mounting styles to ensure mechanical and electrical compatibility.
