Application Scenarios
-
Industrial Automation PCs (IPCs) : Consolidates multiple peripheral connections (keyboards, scanners, USB drives) into a single high-density I/O block on motherboard designs with limited edge real estate.
-
Smart Kiosks & POS Terminals : Provides reliable, long-life interconnects for customer-facing self-service stations requiring both legacy (USB 2.0) peripheral support and high-speed (USB 3.0) data transfers.
-
Telecommunications & Network Hubs : Ideal for network edge devices and routers that require extensive physical diagnostic, expansion, or configuration interfaces on the front panel.
-
Medical Diagnostic Equipment : Ensures stable, interference-free simultaneous connections between diagnostic mainframes, handheld imaging sensors, and external data storage drives.
Frequently Asked Questions
Is this connector manufactured directly by your facility, or are you a distributor?
We are an ISO-certified direct manufacturer. We handle the entire engineering, tooling, and OEM/ODM manufacturing process in-house, ensuring factory-direct pricing and strict quality control.
Can we customize the gold plating thickness for harsher industrial environments?
Yes. While standard plating is often gold flash, we offer custom plating options up to 30µ" (micro-inches) to meet stringent durability and anti-corrosion requirements for heavy-duty applications.
What are the differences between the top and bottom ports on this stacked connector?
The EU26FB3N12236 integrates two USB 2.0 ports (4 pins each) on the upper two tiers for standard 480 Mbps peripherals, and two USB 3.0 SuperSpeed ports (9 pins each) on the bottom two tiers for 5 Gbps data transmission, all housed in a reinforced stainless steel shield with external spring fingers.
Do you provide 3D CAD models (STEP/IGES) for our PCB layout engineers?
Absolutely. We provide comprehensive technical drawings, PCB footprint layouts, and 3D STEP models to assist your engineering team with rapid integration. Please contact our sales team to request the files.
What is the standard lead time for bulk orders of this stacked USB receptacle?
Standard mass production lead times typically range from 2 to 3 weeks. If you require rapid prototyping, we can deliver sample runs within 3 to 5 business days.
Overview and Application Notes
Overview: The EU26FB3N12236 is an industrial-grade quad-port stacked USB Type-A female receptacle designed for through-hole (DIP) PCB mounting. Engineered to maximize front-panel I/O density in space-constrained industrial systems, it integrates two upper USB 2.0 ports (4 pins each) and two lower USB 3.0 SuperSpeed ports (9 pins each), delivering a combined 26-pin configuration in a single high-profile block. Built with a high-durability stainless steel shell (with front lead-in spring fingers), UL 94V-0 rated HTN/LCP insulators, and gold-plated copper alloy contacts (C5191 for USB 2.0, C2680 for USB 3.0), it supports up to 1.8A (USB 3.0) and 1.5A (USB 2.0) per port at 30V AC/DC. Tested to 1,500 mating cycles across an operating temperature range of -55°C to +105°C, it provides a rugged, factory-direct connectivity solution for industrial automation, IPCs, and networking hardware.
Application Notes
-
PCB Layout & Stacking Height: Ensure precise board hole alignment for all 26 signal pins and multiple outer shell stakes. The elevated four-layer profile requires adequate vertical clearance within the chassis enclosure.
-
Grounding & EMI Shielding: Solder all structural shield tabs directly to the PCB ground plane to guarantee full 360° EMI/RFI protection, preventing crosstalk between the high-speed USB 3.0 (5 Gbps) and USB 2.0 (480 Mbps) data lanes.
-
Thermal Profiling: Optimized for standard wave soldering processes. Verify that pre-heat and peak wave temperatures do not exceed the thermal threshold of the UL 94V-0 thermoplastic housing.
-
Power Delivery Routing: Route separate, adequately widened copper traces for the VBUS lines to support up to 1.8A per USB 3.0 port and 1.5A per USB 2.0 port without inducing localized voltage drops.
