PENGLIN D-Type BNC Panel Mount Connector (50 Ohm) – Female-to-Female Pass-Through Coax Adapter
Product description
Key takeaways
If you’re wiring up a CCTV or other coaxial link, a BNC feed-through adapter is one of those parts that can save time and keep the setup looking tidy. This PENGLIN D-Type BNC panel mount connector is a female-to-female pass-through coupler designed to connect two BNC coax cables together via a bulkhead/panel opening.
On paper, it’s a straightforward solution: two BNC socket ends, a 50 ohm impedance design, and a zinc alloy housing that should hold up better than the cheapest plastic alternatives. That said, it’s still a small component—so it won’t magically improve a poor cable run or incorrect installation. The “worth it” factor mainly comes down to whether you actually need a panel-mount feed-through style connector.
It also uses an opening size of 24mm for the panel mount, so it’s not a universal fit for every enclosure without checking your cut-out size first.
It’s a good fit if you’re building or servicing surveillance camera cabling, creating a clean network of interconnections, or extending a coax segment without fuss. You may want to skip it if your project doesn’t need panel mounting, or if you’re not working with 50 ohm BNC coax infrastructure.
What stands out
The core idea here is simple: a bulkhead-style BNC socket-to-socket adapter. That makes it useful when you want the connector to sit properly in a panel or enclosure, rather than relying on a cable-only join.
A zinc alloy housing is a solid practical choice for a connector that may be handled during installs and troubleshooting. The description also notes the centre pins are made of copper—again, nothing revolutionary, but it’s the kind of detail that matters for coax work where contact quality and consistency are the goal.
Another thing worth noting is how the impedance is specified as 50 ohm. If your cameras or coax system expect 50 ohm, this aligns with that requirement.
Where it shines in day-to-day use
Imagine you’re mounting a small surveillance control box or junction plate in a corner of a workshop. You’ve already got two coax cables—one feeding in, one continuing to another point—and you want a neat pass-through rather than a dangling inline adapter. This panel mount connector lets you join the coax runs at the enclosure itself, keeping the connection point protected and easier to trace later.
That “serviceability” angle is often what separates a decent installation from one you regret after the first few maintenance visits. Being able to check the connection quickly matters more than people expect.

Things to double-check before you buy
This is where projects can trip up, even when the connector itself is fine.
First, check the panel cut-out/opening requirement. The listed opening size is 24mm, so if your enclosure has a different hole size, you may not be able to mount it cleanly.
Second, confirm your coax system is aligned with a 50 ohm expectation. If your setup is meant for a different impedance, you wouldn’t want to “make it fit” with the wrong type.
Finally, this is a panel mount socket. If your use case is purely an inline join between two cables with no need for a bulkhead connection, other approaches may be simpler.
Should you buy it?
Worth considering if you want a female-to-female BNC pass-through connection that can be mounted in a panel, and your surveillance/CCTV coax infrastructure is based around 50 ohm BNC connections. The zinc alloy housing and copper centre pins are the sort of practical, build-minded details that make sense for real installs.
It might not be a great match if you don’t need panel mounting, if your enclosure opening isn’t 24mm, or if your coax system doesn’t match the 50 ohm impedance. In those cases, you’ll likely spend more time working around the wrong fit than you save.
