USB Connectors
Our USB connector range covers all standard USB types in PCB-mount and panel-mount configurations, female and male variants, and vertical and right-angle orientations.
USB Type A
The standard host-side rectangular connector used on computers, chargers, and hubs. Available in USB 2.0 (4-contact) and USB 3.0/3.1 (9-contact). Panel-mount Type A sockets are widely used in industrial equipment and embedded systems requiring front-panel USB access.
USB Type B
The standard device-side connector for USB 2.0 peripherals including printers, scanners, and laboratory instruments. The square profile with beveled top corners prevents incorrect insertion.
USB Type C
The current universal standard supporting USB 3.1/3.2/4.0, USB Power Delivery up to 240W, DisplayPort Alt Mode, and Thunderbolt 3/4. The reversible connector eliminates incorrect insertion. Increasingly standard in all new product designs.
USB Mini and Micro
Legacy device-side connectors for cameras, GPS devices, and mobile devices. Micro-B USB 3.0 (10-contact) is used on external hard drives. Essential for replacement and maintenance of existing equipment.
USB Mounting Styles
| Style | Description | Best For |
|---|---|---|
| Vertical PCB | Opening faces up, perpendicular to PCB | Top-access enclosures |
| Right-angle PCB | Opening faces PCB edge | Edge-access, panel-flush mounting |
| Panel mount | Mounts through panel cutout with flange | Front-panel access, industrial enclosures |
| SMD | Surface-mount pads | Automated PCB assembly, thin designs |
HDMI Connectors
Our HDMI connector range covers Type A (standard 19-pin), Type C (Mini HDMI), Type D (Micro HDMI), and Type E (automotive locking) in PCB-mount and panel-mount configurations.
HDMI Type A supports all versions from 1.0 to 2.1 (up to 48 Gbps, 10K, eARC). Type C and Type D are electrically identical to Type A but in smaller form factors for compact cameras, tablets, Raspberry Pi 4, and ultra-compact devices. Type E adds a vibration-resistant locking tab for automotive infotainment systems.
RJ45 Connectors
Our RJ45 connector range covers 8P8C PCB-mount and panel-mount sockets for Ethernet, network, and PoE applications supporting 10BASE-T through 10GBASE-T.
| Variant | Feature | Best For |
|---|---|---|
| Standard PCB mount | Vertical or right-angle | General Ethernet PCB design |
| With integrated magnetics | Built-in transformer and CMC | Direct PCB-to-Ethernet, no external magnetics |
| With LEDs | Integrated link/activity indicators | Status indication without external LEDs |
| Panel mount | Bulkhead flange | Front/rear panel Ethernet ports |
| Shielded | Metal shell | EMI-sensitive industrial and automotive |
PoE support: IEEE 802.3af (15.4W), 802.3at (30W), 802.3bt (90W). Shielded RJ45 recommended for PoE+ and PoE++ applications.
BNC and RCA Connectors
Our BNC and RCA connector range covers coaxial RF, video, and audio connectors in PCB-mount and panel-mount configurations.
BNC (Bayonet Neill-Concelman) uses a quarter-turn bayonet lock for secure vibration-resistant connection, rated to 4 GHz. BNC 50 ohm is used for RF test equipment, data communications, and radar. BNC 75 ohm is used for CCTV, SDI video, and broadcast equipment. Mixing impedances causes signal reflections and degraded performance.
RCA (phono connector) is the standard for analog audio and composite video in consumer AV equipment. Color-coded: red/white for stereo audio, yellow for composite video.
PCB Mount vs Panel Mount
| Factor | PCB Mount | Panel Mount |
|---|---|---|
| Mechanical stress | Forces on PCB solder joints | Forces absorbed by panel/chassis |
| Serviceability | PCB must be accessible | Accessible from outside enclosure |
| IP sealing | Difficult | Gasket-sealable for IP-rated enclosures |
| Cost | Lower | Higher (panel cutout, hardware) |
| Best for | Internal connections, compact designs | Industrial enclosures, high-mating-cycle |
Frequently Asked Questions
What is the difference between USB Type A and Type C?
USB Type A is the rectangular host-side connector supporting up to USB 3.1 (10 Gbps). USB Type C is the reversible oval connector supporting up to 40 Gbps, USB Power Delivery up to 240W, and alternate modes. Type C is the current universal standard for new designs.
What is the difference between BNC 50 ohm and 75 ohm?
50 ohm is for RF test equipment, data communications, and radar. 75 ohm is for video (CCTV, SDI, composite) and broadcast equipment. Always match impedance to your cable and equipment specification.
What RJ45 connector do I need for PoE?
Standard RJ45 connectors support PoE. For high-power PoE (802.3bt, up to 90W), ensure the connector and cable are rated for the current. Shielded RJ45 is recommended for PoE+ and PoE++ to minimize EMI.
What HDMI connector does Raspberry Pi use?
Raspberry Pi 4 uses Micro HDMI (Type D). Raspberry Pi 3 and earlier use full-size HDMI (Type A). Raspberry Pi Zero uses Mini HDMI (Type C). Always check the specific board version before ordering.
Can I use a panel-mount USB connector with any USB cable?
Yes. Panel-mount USB connectors are electrically identical to PCB-mount connectors and compatible with standard USB cables. The panel-mount variant adds a flange or nut for chassis mounting.
Conclusion
Yoeruyo supplies the complete interface connector range: USB Type A/B/C/Mini/Micro, HDMI Type A/C/D/E, RJ45 Ethernet, and BNC and RCA coaxial connectors in PCB-mount and panel-mount configurations with bulk and OEM pricing.
