Our BNC plugs are easy to use, effective, and constructed from the highest-quality material. Let’s review how they work:

How do BNC connectors work?

BNC (Bayonet Neill-Concelman) RF connectors make it easy to connect coaxial cables with radio-frequency equipment like radios and TVs, composite video on commercial video devices, and ethernet networks. The amount of ohms indicated basically measures electrical impedance along the coaxial cable.

They’re easy to install with a simple “snap and lock” mechanism, which ensures a high-quality connection. They arrive tested to 3 GHz. And they come in handy when you need to combine them with, say, an RCA connector on the end of the coaxial cable.

All of our BNC connectors are machined from virgin brass (in accordance with MIL-C39012) and plated with bright nickels, unlike less reliable connectors made from cheaper die cast bodies.

So what’s different?

Physically, the main differences can be found in the center pins and dialectric insulators. 75-ohm BNC connectors feature Teflon as a dialectric, and surround the outer spring fingers with air. Its center pin maintains a consistent diameter in both the front and rear areas (this is important—read on to find out why). 50-ohm connectors, on the other hand, use Delrin to surround the spring fingers, and its center pin is larger in the crimp area. You’ll need different crimp tools for each type of center pin.

What’s the difference in functionality?

Both connectors can mate without damage, but you can’t really mix and match and expect to get the same video quality. For example, if you installed a traditional 50-ohm BNC connector on a 75-ohm coaxial video cable, the digital signal would be significantly distorted.

Basically, 50-ohm BNC connectors are used for older analog video applications. But for higher performance A/V applications like HDTVs, 75-ohm BNC devices are necessary. 75-ohm BNC connectors can, however, be used for analog purposes.

(Tip: The center pin MUST have the same diameter in the crimp area as the mating area in order to have true 75-ohm impedance. If a connector claims to be 75-ohm but doesn’t have a consistent pin length, it’s an inferior product that won’t give you what you need.)

Some BNCs have enclosed beryllium copper spring fingers. Is this necessary?

Unless you’re expecting your BNC connector to be subject lots of abuse (like the need for thousands of matings, or foreign objects poking into the connector interface), there’s no need for this design.

How does your cable pull strength stack up?

Our BNC plugs feature a diamond knurling for maximum cable retention. After testing thousands of cable assemblies, our BNCs recorded a pull-test performance of 49.3 inch lbs. on the 735A cable—unparalleled strength and durability. The industry minimum is just 30 lbs.

Is there anything else I need?

We can provide just about anything you need to install BNC connectors, including 75-ohm pin crimpers, universal BNC termination kits, analog video kits, center conductor trimmers, Corex coax strippers, clothespin strippers, and universal crimpers.

CAT5e? CAT-5e? CAT 5-E? To dash or not to dash or where to dash? Don’t worry about it.

We’ve upgraded our site’s search capabilities to handle queries however they may be typed, which means its much, much easier to find the product or information you need. Because (shameless boast coming), when you’ve got a comprehensive catalog bursting with connectivity solutions like ours, the ability to find what you need without drowning in a sea of cable assemblies, connectors, and A/V devices is key.

The upgraded search box can now handle just about any part number or keyword, regardless of how its typed. For example, you’ll see CAT5 and CAT6 cable solutions spelled in just about every possible way (more often than not, there won’t be a commonly accepted standard for these sorts of things). Enter any of the terms, and you’ll be able find all the CAT5e cables, splitters, extenders and receivers, and other accessories we provide.

Furthermore, we’ve added a slew if increased options and features that make easier to drill down within a particular search category, and find more specific products or information. For example, if you search for “coaxial connectors” (which returns 217 results—everything from 7-16 DIN connectors to BNC/RCA termination kits), you’d still have to wade through 25 pages full of relevant products. But if you customize your search by price, category, manufacturer, or department, you can quickly pare down the results and find what you need.

Don’t forget about our product wizards for adapters and cable assemblies either — both of which can quickly direct you to the right product page.

Give us a call if you ever can’t quite find a specific product (or if you’re unsure of which product is best for a job anyway)— we’ll get you set up in no time.

HDMI Over Single CAT5E/CAT6 Splitters and Receivers

Installing HDMI over CAT5E/CAT6 is a great way to boost your entertainment setup. In fact, our HDMI Over Single CAT5E/CAT6 Splitters and Receivers can extend an HDMI signal up to 164 feet (and split it out to up to eight separate HDTVs).

But let’s say you get it all set up, and that Avatar DVD just isn’t as showing up as visually riveting as you’d expected.

The problem probably lies in the source settings. Most HD source devices (like DVD players, cable/satellite boxes, or gaming consoles like Playstation 3 and XBox 360) come preset to “auto-detect” the picture resolution. If you were connecting them directly to the display (your TV), it would do exactly that.

But if you introduce another device in the channel—like, say, our HDMI over CAT5E/CAT6 baluns, some sources won’t know exactly which resolution they’re supposed to “auto-detect,” and need to be manually set the proper resolution.

Here’s how to do that:

1. Find your source’s remote control (sometimes the toughest part of any HD experience).

2. Go to the settings section, and find the resolution or video output setting it.

3. If it’s currently set to something like “auto-detect.” Shame the source for failing to do so.

4. Manually switch to the resolution you’re expecting, like 1080p, 1080i, 720p, etc. This should solve most picture compatibility issues.

5. Resume watching (this time in the pristine high-definition those blue aliens deserve).

    As amazing as technology is these days, it doesn’t always work as flawlessly as we’ve come to expect and demand. But there’s usually an easy fix available.
