Finding the Model Number on Your Inductive Sensor

Posted by Eric Miller on Thu, Oct 01, 2015

One of the most important parts of integrating an inductive sensor into an application or ordering replacement parts is being able to identify the part and model number of the sensor. That is why knowing how to find the model number on your inductive sensor is so important. This is actually a fairly simple and straightforward process.

Find the model number on your inductive sensor

There are few places where the model number could be on an inductive sensor, so it is generally easy to find. But, in some cases the sensor may not have any printing on it at all. This could occur when the sensor is very small. But, if there is printing or labeling on the sensor, you are in luck!

Finding the model number is as simple as reading the letters and numbers off of the barrel, cable, or sensing face. For our inductive sensors, there will be three letters followed by a number. The first of the three letters should always be an N, meaning inductive. The next letter is based on the line that the sensor comes from, with the most common being B for basic, but a few other examples are E for extended range and M for the Pile Driver series. The next letter is a B or an N, for flush or nonflush, respectively. The number that follows these three letters is the nominal sensing range.

The next section of the model number has to do with the type or style of housing. For a cylindrical housing, it will be the diameter in millimeters, followed by a G for threaded. If it is unthreaded, it will skip right to the housing material, which is usually M for metal nickel-plated brass. The last number in this section is the sensor length in millimeters (threaded length for shielded and thread plus cap height for unshielded. Ex. NBB8-18GM50-E2-V1 & NBN12-18GM50-E2-V1). If the sensor is not cylindrical, this second section will just have the housing style, such as L2 for our Rhino-style housing (Ex. NBB20-L2-A2-V1) or FP for our flat-pack housing (Ex. NCB50-FP-A2-P4-V1).

After the first two sections, the rest of the model number is specific features of that sensor. Following the housing information, next comes the electrical output, followed by special features, and lastly the connection elements if the sensor has a quick disconnect.

If you don’t see a long model number on the sensor, the next best thing to have on it is our 6-digit part number. Sometimes this will be located on the sensing face of a small sensor. If you can find the 6-digit part number, you can type this into our website search box in the top right corner and that will give you the correct model number.

If you are unlucky and don’t have anything printed on your sensor, then the best place to find your sensor information is going to be on the packaging or through the purchasing information. Keeping this packaging is important so that you will always know what the specific model number is for that sensor. If you find the model number on the packaging, the same nomenclature rules from above will apply.

Being able to find the model number on your inductive sensor is very important so that you know what type of replacement you need, or it can help you find the data sheet for that sensor very easily. So be sure you are able to find the model number of your new sensor!
