Overview
The EDAC Inc. 306-027-420-103 is a standard card edge connector receptacle featuring 54 positions arranged in a dual female configuration. It utilizes a 3.96 mm (0.156 inch) contact spacing with a single centerline row design. The unit accepts printed circuit boards with a nominal thickness of 1.57 mm (0.062 inch). Electrical specifications include a current rating of 5 A and gold-plated copper alloy contacts. The insulator body is constructed from thermoplastic polyester, providing vertical panel mount installation.
Feature Summary
- Dual female contact configuration for secure board retention
- Low profile insulator body construction
- Gold-plated copper alloy contact termination
- Vertical panel mount installation style
Applications
- Industrial control system interconnects
- Telecommunications equipment backplanes
- Test and measurement instrument modules
Procurement Notes
Verify the specific ordering suffix against the manufacturer datasheet to confirm pin count, plating type, and mounting hardware requirements. Ensure the target PCB thickness matches the 1.57 mm specification. Confirm that the vertical panel mount orientation aligns with the mechanical assembly constraints before finalizing the purchase order.
Selection Notes
Select this component when a high-density connection with 54 positions is required within a limited vertical space. The 3.96 mm pitch accommodates standard board widths while maintaining robust electrical performance. Consider the thermoplastic polyester insulation for applications requiring stable dielectric properties under moderate thermal loads.
Part Context
This part belongs to the EDAC 306 series of standard card edge connectors. The series provides various position counts and mounting options for edgeboard applications. The 306 series is designed for reliable signal transmission in environments requiring durable mechanical connections between the connector and the peripheral circuit board.
Replacement Considerations
Cross-reference compatible parts within the EDAC 306 series family. Verify identical 54-position count, 3.96 mm pitch, and dual female configuration. Ensure replacement units maintain the same vertical panel mount style and 1.57 mm board thickness acceptance capability.
