Double Layer USB A

The Double Layer USB A connector is a cutting-edge connectivity component designed to meet the growing demand for compact, high-performance data and power transmission in industrial equipment, consumer electronics, and automotive systems. As a dual-stack USB A interface, it integrates two independent USB A ports in a single, space-saving housing, making it an ideal choice for devices where board space is limited but multiple USB connections are required.

Key Features

Dual-Stack Design for Space Efficiency: By stacking two USB A ports vertically, this connector reduces the footprint on PCBs by up to 50% compared to traditional side-by-side USB A connectors. It’s perfect for compact devices like industrial controllers, portable chargers, and automotive infotainment systems, where maximizing space utilization is critical.

High-Speed Data & Power Delivery: Compliant with USB 2.0/3.0 standards, the Double Layer USB A supports data transfer speeds of up to 5 Gbps (USB 3.0) and power delivery of up to 2.4A per port. This ensures fast file transfers, stable device charging, and reliable communication between peripherals such as external hard drives, printers, and sensors.

Robust & Durable Construction: Built with high-quality materials including镀金 contacts and flame-retardant plastic housings (UL94 V-0 rated), the connector offers excellent corrosion resistance, wear resistance, and mechanical strength. It can withstand up to 10,000 insertion/extraction cycles, making it suitable for harsh industrial environments and high-use applications.

Plug-and-Play Compatibility: Fully compatible with all USB A-enabled devices and cables, the Double Layer USB A requires no additional drivers or software. It supports hot-swapping, allowing users to connect or disconnect peripherals without powering down the host device, enhancing usability and efficiency.

Versatile Mounting Options: Available in through-hole, surface-mount (SMT), and panel-mount configurations, the connector can be easily integrated into various PCB designs and enclosure types. Customizable pinouts and orientation (vertical/horizontal) are also available to meet specific application requirements.

Industrial Automation: Ideal for PLCs (Programmable Logic Controllers), HMI (Human-Machine Interface) panels, and industrial sensors, providing reliable connectivity for data logging, device control, and firmware updates.

Consumer Electronics: Used in multi-port USB chargers, desktop computers, gaming consoles, and smart TVs, enabling users to connect multiple peripherals (e.g., keyboards, mice, external storage) simultaneously.

Automotive Electronics: Suitable for in-car infotainment systems, USB charging ports, and telematics devices, supporting high-temperature operation (-40°C to 85°C) and vibration resistance.

Medical Devices: Compliant with medical industry standards (e.g., ISO 13485), the connector is used in diagnostic equipment, patient monitors, and portable medical devices, ensuring secure data transmission and stable power supply.

Telecommunications: Integrated into routers, switches, and network servers, providing additional USB ports for network management, backup storage, and peripheral connectivity.

Q1: What is the difference between USB 2.0 and USB 3.0 versions of the Double Layer USB A connector?

A1: The USB 2.0 version supports data transfer speeds up to 480 Mbps and power delivery up to 2.4A, while the USB 3.0 version offers speeds up to 5 Gbps (10x faster than USB 2.0) and maintains the same power output. Both versions are backward compatible with USB 1.1 devices.

Q2: Can the Double Layer USB A connector be used for charging only?

A2: Yes. The connector can be configured for charging-only applications (e.g., multi-port chargers) by disabling the data pins. It supports fast charging protocols such as QC 3.0 (Quick Charge) and PD (Power Delivery) when paired with compatible controllers.

Q3: What is the operating temperature range of the connector?

A3: Standard models operate from -40°C to 85°C, making them suitable for most industrial, automotive, and consumer applications. High-temperature variants (-55°C to 125°C) are available for extreme environments.

Q4: Is the Double Layer USB A connector waterproof?

A4: Standard models are not waterproof, but IP67-rated waterproof versions are available for outdoor or wet environments (e.g., marine electronics, outdoor charging stations). These feature sealed housings and water-resistant contacts.

Q5: Can I customize the connector’s pinout or housing color?

A5: Yes. We offer custom pinout configurations (e.g., rearranged power/data pins) and housing colors (black, white, gray) to match your product design. Minimum order quantities (MOQs) apply for customizations.

Q6: What certifications does the Double Layer USB A connector have?

A6: The connector is certified by USB-IF (USB Implementers Forum), ensuring compliance with USB standards. It also meets RoHS, REACH, and UL safety standards, making it suitable for global markets.
