Frequently Asked Questions
-
Q: What is the maximum wall thickness for this 23.5 inch housing?
A: With 23.5 inch penetration, maximum wall thickness is approximately 22.5 inches (572 mm). Calculation: 23.5in minus 0.5in minimum thread engagement minus 0.06in gap minus 0.44in safety margin. This is the longest standard penetration available. -
Q: Is the probe already installed in this housing?
A: Yes. Option 28 means the 3300 XL 8mm probe is included and factory installed. The probe has multiple approvals (CSA/ATEX/IECEx) for hazardous locations. -
Q: What is the probe cable length?
A: The probe has a 1.0 meter (3.3 feet) cable. This provides flexibility for proximitor mounting. Extension cables can be added to reach 5m or 9m total system length. -
Q: Why no fittings included with option 00?
A: Option 00 means without fittings. For this long penetration housing, you may need custom conduit adapters. Order fittings separately based on your specific cable entry requirements. -
Q: Can this housing withstand internal pressure?
A: No. The plastic housing is certified for NEMA 4X and IP66 (external water protection) but is not designed to resist internal or external pressure. For pressurized applications with long penetrations, contact Bently Nevada about custom designs.

Great as long as you know its limitations; runs warm; monitor settings may need to be changed
I reluctantly gave up MagSafe and joined the USB-C future when my employer issued me a new 2019 16" MacBook Pro. Searching for a way to connect my various peripherals I settled on this hub as a reasonable way to connect a 4K display, pass power from the laptop charger (albeit not the full 96W; macOS reports 79W after hub losses—good enough most of the time), connect 1GigE, and provide a few spare USB ports and occasionally-used SD card slots. I've learned a few things: A port that looks like USB-C does not pass video unless it is a "Thunderbolt" port (look for the lightning bolt logo, apparently); connecting a USB-C-to-mini-DisplayPort adapter to the USB-C port on this hub did not allow my monitor to work. Lesson learned. The HDMI port did work, and did pass 4K@60Hz, but only after I adjusted my monitor settings. At first I was convinced either my HDMI cable or this hub were defective, because macOS would only allow me to select 4K@30Hz. I have an LG 4K display, and from reading forums, one must enable 60Hz in the on-screen display menu before the monitor will tell the computer it is capable of displaying 60Hz video. For my monitor, that meant changing "Ratio" in "Quick Settings" to "Original" (it defaulted to "Wide", with a separate configuration for each port), as well as turning on "HDMI ULTRA HD Deep Color" from "Picture" -> "Picture Adjust." After I changed those two settings, 60Hz was not available until I unplugged the HDMI cable from the hub and plugged it in again. After that I had buttery smooth 4K video at 60Hz. The hub works as advertised, at least for my configuration. The 1GigE port works well, and is equivalent to a direct USB-C to Ethernet adapter I tried. It does run warm to the touch as other reviewers have reported. That's not problematic, but I'd prefer it pass the missing 17W to the laptop rather than dissipate it as heat. Time will tell how well the hub holds up, but for now I'm happy. In summary: if you have a new Mac this hub will likely work for you, though you may need to adjust your monitor settings.

Older flash drives might not work.
Port labels are too faint to read easily and the PD out port isn't labelled (I suppose they thought it was obvious since it has a fixed cable).
The USB ports are speedy except it won't recognize any of my several SanDisk Cruzer Glides. Others flash drives work okay.
Works great as an iPhone USB C to TV HDMI converter.

Works perfectly with MacBook
Bought these adapters after getting a wireless mouse for a MacBook and realizing the USB receiver couldn’t be connected directly because the Mac doesn’t have a regular USB port. These adapters solved the problem completely.
They work exactly as expected and were very easy to use. The quality feels good and the color matches the MacBook nicely, so they don’t look cheap or out of place. Small, simple, and stylish adapters that do their job well

Anker adapters
These Anker adapters honestly saved me. The quality feels very premium and they work perfectly with no disconnecting or recognition issues. I used them to connect USB-C accessories and everything worked instantly and smoothly.
They’re compact, durable, and super convenient to carry around for my content creation setup. The metallic finish also feels much more reliable compared to cheaper adapters I’ve tried before.
Definitely recommend this brand if you want something dependable and high quality for your devices. ✨
