Overview
The EDAC Inc. 306-027-400-112 is a standard card edge connector featuring 54 positions in a single row with a 3.96 mm (0.156 inch) pitch. Designed for dual-edge card insertion, it utilizes tin-plated copper alloy contacts and accepts printed circuit boards with a nominal thickness of 1.57 mm (0.062 inch). The unit employs a green thermoplastic insulator body and supports panel mounting in a vertical orientation. It is rated for 5 A current at maximum operating temperatures of +105°C and minimums of -40°C.
Feature Summary
- Dual-edge contact configuration for secure board retention
- Low-profile insulator body design
- Tin-plated termination for reliable conductivity
Applications
- Rack and panel interconnect systems
- Industrial control modules
- Computing and storage hardware backplanes
Procurement Notes
Verify the specific ordering suffix to ensure compatibility with required contact plating and insulation color specifications. Confirm that the selected variant matches the intended PCB thickness and mounting style requirements for your assembly. Cross-reference the manufacturer datasheet to validate electrical ratings against system constraints before finalizing procurement orders.
Selection Notes
Select this component when a high-density single-row interface is required for dual-edge cards. Ensure the application environment remains within the specified temperature range of -40°C to +105°C. Verify that the 3.96 mm pitch aligns with the target board layout and that the panel mount orientation fits the mechanical enclosure constraints.
Part Context
This part belongs to the EDAC 306 series, which provides extensive design options for card edge applications. The series allows customization of contact terminations, mounting options, and guide solutions. EDAC specializes in complex interconnect products for computing, medical, aerospace, and industrial sectors, emphasizing quality assurance and logistical efficiency.
Replacement Considerations
Direct substitutes require matching the 54-position count, 3.96 mm pitch, and dual-edge acceptance. Verify that alternative components support the same 1.57 mm board thickness and panel mount vertical orientation to maintain mechanical integrity.
