USB Type-C Round Pass-Through Coupler Panel Mount 24mm Cutout Silver / Black

Specifications:

• Interface: USB Type-C Female to Type-C Female (Pass-through)
• Mounting Cutout Diameter: 24mm
• Front Bezel Profile: Round 
• Material: Metal Alloy / Industrial Plastic 
• Data Transfer Support: Yes (USB 2.0 / 3.0 compatibility) 
• Power Delivery Support: Yes
• Connection Method: Plug and Play (No soldering required)
• Fastening Mechanism: Rear threaded locking nut

Minimum hardware to get started:

• Enclosure or mounting panel : to provide a rigid physical surface to mount the coupler.
• 24mm Hole Saw or Step Drill Bit : required to cut the exact diameter hole needed for a flush, secure fit without gaps.
• Internal USB Type-C Cable : to bridge the connection from your internal electronics (like a Raspberry Pi or custom PCB) to the rear port of this coupler.

Safety Warnings:

• Clearance Warning: Ensure you have adequate depth inside your enclosure. The internal Type-C cable will need space to plug in and bend safely without putting mechanical stress on the internal port.
• Torque Warning: Hand-tighten the rear locking nut. Over-tightening with a wrench can crack acrylic or 3D-printed plastic panels. 

Accessories
Included in the Box:

• 1× Type-C Round Pass-Through Coupler (24mm Cutout)
• 1× Threaded Locking Nut
• 1× Protective Dust Cap 

Frequently Asked Questions(FAQs)

• Is this coupler compatible with standard USB-C cables?
  Yes, both the front and rear ports accept any standard USB Type-C male cable.
• Does this support high-speed data transfer?
  It acts as a direct pass-through, so it supports the data speeds (USB 2.0 or 3.0) dictated by your host device and internal cables.
• Can I use this for USB Power Delivery (PD) charging?
  Yes, all pins are mapped straight through, enabling standard PD negotiation between the charger and your device.
• Will this work on a metal enclosure?
  Yes, the coupler can be mounted on metal, plastic, or wood panels, provided the material thickness is within the thread limit.
• What is the maximum voltage this coupler can handle?
  It safely handles standard USB Type-C voltages up to 20V for Power Delivery applications.
• Can it support 5A fast charging?
  Yes, as long as the internal and external cables connected to it are also rated for 5A.
• Will adding this coupler cause a voltage drop?
  Because it introduces two additional mechanical connection points, there may be a marginal voltage drop, but it is generally negligible for standard projects.
• Do I need to solder any wires to this coupler?
  No, this is a fully passive, plug-and-play pass-through connector requiring no soldering.
• Are the ports reversible like a standard USB-C connection?
  Yes, you can plug your Type-C cables into both the front and back ports in any orientation.
• How tight should the rear mounting nut be?
  Hand-tighten it firmly; over-tightening with a wrench, especially on plastic panels, can crack your enclosure.
• Do I need any software drivers to use this coupler?
  No, it is a purely physical hardware bridge and requires no software or drivers.
• Will this interfere with my Arduino or ESP32 serial communication?
  No, it simply extends the physical connection and will not alter or interfere with serial data streams.
• Do I need to configure my Raspberry Pi for USB-C pass-through?
  No configuration is needed; the Raspberry Pi will treat the connection exactly as if the external cable were plugged directly into the board.
