I'm a student doing research in a physics lab and we often have the need for a certain type of BNC cable splitter. This splitter has a BNC jack which accepts a single coaxial cable as input. It has two jacks for output. It routes the center pin of the input to the center pin of one of the outputs and it routes the shield of the input to the center pin of the other output.

Understanding the Functionality of BNC Splitters

To give an example, one thing we use this type of splitter for is to amplify a voltage (center pin) with respect to ground (outer pin) using a purely differential amplifier which takes two BNCs as input.

Moreover, BNC splitters are often essential in experiments requiring precise signal distribution. Using a splitter that isolates ground and signal can significantly reduce noise and interference, leading to more accurate measurements and results.

Common Questions about BNC Splitters

My questions are: 1. Is there a name for this type of splitter? 2. Is there anywhere that sells nice, high quality splitters of this type? We can homebuild them but it would be better if we can find a place to buy them from.

I've tried searching for this, but I haven't turned anything up. I appreciate any and all answers!

Edit: I should note that another thing we use this type of splitter for is connecting a two point resistance measurement from a multimeter to our breakout box. The multimeter has banana plugs and we want to connect the positive wire and the negative wire to different jacks on the breakout box (corresponding to different contacts on our sample inside a dilution refrigerator). It seems to me that a splitter like I described is necessary for this.

Where to Find Quality BNC Splitters

Finding the right BNC splitter that separates ground and signal can be a challenge due to its specialized nature. When searching for high-quality splitters, consider suppliers specializing in scientific and laboratory equipment. These suppliers are more likely to offer robust and precision-engineered splitters designed to meet the demanding requirements of research and testing environments.

Need an M12 Connector? Don't Forget to Ask about Coding!

Think about asking someone to go to the store to purchase a light bulb. It seems easy enough on the surface, but they’ll realize there are several options to choose from based on preferences and applications. The same holds true for M12 connectors.

At quick glance, it’s difficult to tell one M12 connector from another. Instead, the vital differences can be found inside the connector in terms of how it’s keyed in the connector insert and how the pins are configured which prevent or allow mating. These configurations are called the connector’s “coding”; codings are necessary to be able to differentiate and identify the various M12 connectors.

As workers in the field or on the plant floor disconnect, reconnect and install new connectors quickly, codings also ensure that an M12 connector is never inserted into the wrong circuit or used in the wrong application. (This is one of the reasons electrical outlet plugs vary between Europe and the United States, too: They feature different shapes to prevent mis-mating.) When you try to plug an M12 connector into the wrong receptacle, it won’t fit.

A wide range of codings makes M12 connectors applicable within many different markets and applications. They can often be found in agriculture, alternative energy, communications, factory automation, food and beverage, measurement and control, robotics and transportation.

Here’s a quick and straightforward overview of what the most common M12 codings mean and where they can be used …

The 5 Most Common M12 Connector Codings

M12 A-coded connectors are widely used and have been around for decades. They’re also the most versatile in terms of the types of connections they support, as well as the number of pins housed in the connector (between three and 12 or even more). They support direct current (DC) connections and are used to connect sensors and actuators, as well as Ethernet connections up to Category 5e (four-pair connections).

M12 B-coded connectors are for network or non-Ethernet fieldbus connections (the most common is PROFIBUS). They can be used for sensor connections as well. Over time, we may see fewer of these connectors in use as PROFIBUS and similar fieldbus protocols are replaced with Ethernet.

M12 C-coded connectors are used for alternating current (AC) applications, including motor connections. In the future, we predict that some of the applications currently calling for M12 C-code connectors may transition to K-coded and S-coded connections (see below to learn more about these codings).

M12 D-coded connectors are used primarily for industrial Ethernet connections, such as PROFINET and EtherNet/IP. They provide a form factor that supports two-pair connections. Unlike M12 X-coded connectors, D-code doesn’t support Gigabit Ethernet; it only supports Fast Ethernet (100 Mb/s).

Lastly, M12 X-coded connectors are a more recent development designed specifically to support Gigabit Ethernet. In addition to preventing mis-mating, these connectors are designed with walls between each group of two pins (four groups of two pins overall). The walls prevent crosstalk and interference to achieve excellent Category 6 or 6A performance (up to 10 Gb/s).

Additional M12 Codings You Need to Know for Power Connections

This brings us to the next group of M12 connectors, which support higher voltage and current ratings over M12 connections. In these connectors, the pins are spaced in a way that provides proper electrical capabilities and prevents mis-mating:

• M12 K-coded connectors have five pins, are intended for AC connections (AC motors, motor-operated switches, PSUs, etc.) and are rated for 630 volts.
• M12 S-coded connectors have four pins, are also intended for AC connections and are rated for 630 volts.
• M12 L-coded connectors have either four or five pins, are intended for DC connections (DC motors and drives, LED fixtures, I/O modules, etc.) and are rated for 63 volts.
• M12 T-coded connectors have four pins plus a functional earth pin, are also intended for DC connections and are rated for 63 volts.

And, finally, we have the M12 Y-coded connector. This hybrid connector supports power and data connections over the same connector; inside, a wall separates the power and data pins. This can save valuable space and reduce installation time and material in applications that call for both.

The next time someone mentions an M12 connector , make sure you ask: What kind of M12 connector do you need? Knowing the answer will save time and reduce frustration when you’re ready to make your selection.
