Application Scenarios
-
Industrial Panel PCs & HMIs : Utilizes the mid-mount design to drastically reduce the vertical profile of the motherboard, enabling ultra-slim touchscreen enclosures without sacrificing physical durability on the factory floor.
-
Medical Diagnostic Equipment : Provides highly reliable, 10,000-cycle high-speed 5 Gbps data connections essential for portable imaging carts and patient monitoring systems.
-
Test & Measurement Devices : Delivers a rugged, through-hole anchored diagnostic interface capable of withstanding constant plug-ins and lateral stress from field technicians.
-
Embedded Computing & Thin Clients : Solves space constraints in compact mini-PCs by sinking the connector directly into the PCB cutout, maximizing internal layout efficiency and airflow.
Frequently Asked Questions
What is the standard Minimum Order Quantity (MOQ) for this USB 3.0 mid-mount receptacle?
Our standard MOQ for tape-and-reel or tray packaging is typically 1,000 to 3,000 pieces per batch for volume production. However, we offer flexible prototype quantities for engineering validation and NPI builds.
Can the gold plating thickness on the contacts be customized?
Yes. While Gold Flash is our standard offering, we can customize the plating thickness up to 15μ" or 30μ" gold over nickel to meet strict military or harsh-environment industrial specifications upon request.
Is this connector a functional replacement for major brands like TE or Amphenol?
Yes, the 11.EU09F2L3N12343SR features an industry-standard mid-mount footprint, making it a cost-effective, drop-in alternative for many tier-1 brand part numbers. We highly encourage requesting 3D CAD models (STEP/IGES) to verify your PCB cutout tolerances.
Are the thermoplastic housings compatible with reflow soldering?
This specific part is designed with DIP through-hole pins optimized for wave soldering. If your automated assembly process requires Pin-in-Paste (intrusive reflow), we can manufacture the insulator using specialized LCP plastics. Please specify this during your RFQ.
What are the typical lead times for bulk OEM production?
Standard factory lead times range between 2 to 4 weeks, depending on order volume and raw material availability. Expedited production schedules can be arranged for critical OEM projects.
Overview and Application Notes
Overview The EU09F2L3N12343SR is an industrial-grade USB 3.0 Type-A female receptacle featuring a space-saving mid-mount (sink-board) architecture. Engineered with a rugged right-angle through-hole (DIP) design and integrated locating pegs, it delivers superior mechanical stability against high mating forces in harsh environments. Capable of supporting 5 Gbps SuperSpeed data transfer and guaranteed for 10,000 mating cycles, this connector is the ideal choice for OEM industrial PCs, diagnostic equipment, and low-profile commercial electronics. As a factory-direct partner, we provide tailored manufacturing and packaging solutions to seamlessly integrate into your automated assembly lines.
Application Notes
-
Footprint & Clearance: The mid-mount configuration requires a precise PCB cutout. Verify 3D models and mechanical drawings to ensure adequate clearance for the connector belly to achieve optimal height reduction.
-
Soldering Guidelines: The through-hole contact pins and shell stakes are optimized for standard wave soldering processes. Maintain proper thermal profiles to prevent damage to the high-temperature thermoplastic insulator.
-
Impedance Matching: To maintain 5 Gbps signal integrity, route the SuperSpeed differential pairs (SSTX/SSRX) on your board with a strict 90-ohm differential impedance.
-
EMI/RFI Shielding: Connect the through-hole shell stakes directly to the continuous PCB ground plane to maximize electromagnetic shielding effectiveness in noisy industrial applications.
