Short USB 3.0 Connector

The reverse-side recessed PCB design (1.8mm depth) minimizes vertical space while the horizontal 90° DIP structure ensures stable signal transmission. Metal shell provides EMI shielding, and black polymer base aligns with KKG’s signature industrial aesthetics.

Appearance & Dimensions: The short USB 3.0 Type-A connector retains the rectangular design with slightly rounded corners of the standard Type-A connector, but features a shorter overall length. Dimensions vary slightly by manufacturer — for example, the KKG brand’s short USB Type-A connector measures 12.9mm*12.5mm. There are also vertical-mount short Type-A female connectors as compact as 8.8mm, more space-saving than traditional USB interface connectors.

Pin Definition: The USB 3.0 Type-A connector is equipped with 9 pins. It includes 4 pins from USB 2.0 (VBUS, D-, D+, GND), which are used to supply +5V power, transmit USB 2.0 data, and provide a power loop. The additional 5 pins support USB 3.0 super-speed data transmission, enabling full-duplex communication.

Mechanical Performance: The maximum insertion force is 35N, the minimum extraction force is 10N, and the service life can reach 1500 mating cycles.

Data Transfer Speed: The USB 3.0 version achieves a data transfer speed of up to 5Gbps, the USB 3.1 version up to 10Gbps, and the USB 3.2 version up to 20Gbps.

Material & Craftsmanship: The shell is generally made of brass with matte tin plating, offering easy production, stable dimensions, and low impedance. The terminals are made of phosphor bronze with gold plating, ensuring good elasticity, wear resistance, and low contact impedance. The insulator is mostly made of LCP material, which is high-temperature resistant and has excellent insulation performance, maintaining shape and avoiding bubbling at 260°C.

Leveraging its compact size and stable performance, the short USB 3.0 Type-A connector is widely used across multiple fields:

Consumer Electronics: It serves as a data transfer and charging interface for smartphones, tablets, and other devices. Additionally, it is commonly adopted in audio equipment such as Bluetooth speakers to enable audio data transmission and charging functions.

Personal Computers & Peripherals: Laptops and desktop computers are usually equipped with multiple short USB Type-A ports. These ports connect peripherals like keyboards, mice, printers, scanners, and external storage devices, facilitating data transfer and device expansion for users.

Automotive Electronics: It is widely used in automotive electronic products including car chargers, in-vehicle entertainment systems, and dash cams. It provides power and data transmission channels for devices, meeting drivers’ needs for charging and entertainment in the car.

Medical Devices: Medical equipment such as electrocardiographs, blood pressure monitors, and patient monitors require stable data transmission and reliable power supply. The short USB 3.0 Type-A connector can connect various peripheral devices like sensors and external displays to collect and display patient information.

Industrial Equipment: In industrial scenarios, it is applied to data loggers, embedded systems, diagnostic tools, and other equipment. Its high voltage resistance and corrosion-resistant shell allow it to cope with harsh environments such as factory automation equipment or outdoor monitoring systems.

Smart Home: Smart home products like smart sensors and smart controllers also use this connector to realize device power supply and data communication. It enables users to centrally manage and control these devices through smart home systems.

Q1: Which industrial or commercial devices are these USB-A connectors compatible with?

A1: KKG USB-A series connectors are compatible with industrial controllers (e.g., Siemens SIMATIC PLCs), medical equipment (GE Healthcare monitors), commercial printers (Canon imagePROGRAF), and retail POS systems (Ingenico terminals). They support standard USB-A interfaces for seamless integration.

Q2: What are the data transfer speed and power delivery capabilities of the USB 3.0 models?

A2: USB 3.0 models (e.g., USB 3.0-3152) offer 5Gbps transfer speeds and 5V/1.5A power delivery, supporting 4K video streaming (Blackmagic Design capture cards) and fast charging (Dell Latitude laptops).

Q3: What are the advantages of the metal housing and polymer core design?

A3: The zinc alloy housing (silver, as shown in the left connector) provides IP67 dust/water resistance. The black PBT polymer core withstands -40°C to 105°C, ideal for harsh environments like Schneider Electric inverters.

Q4: What is the insertion cycle lifespan, and what testing standards are applied?

A4: Industrial-grade models meet IEC 61076-2-101 standards, with ≥10,000 insertion cycles (simulating 50 daily cycles in Foxconn production lines for 5+ years of use).

Q5: Do they meet automotive and medical certifications?

A5: Optional models comply with AEC-Q200 (Tesla supply chain) and ISO 13485 (Philips medical devices), along with RoHS/REACH certifications. Suitable for Bosch KTS diagnostic tools and MRI interfaces.
