In a previous blog Flush or Non-Flush, Looks Can Be Deceiving, Jeff mentions the two common housing designs of inductive sensors, flush and non-flush. So what does this mean to you when you are applying an inductive or even a … Continue reading
I am experiencing the future of tradeshows; a networking & educational conference without the travel, the expense, and the suit! I can sit at my desk and make contact with future vendors and customers. Continue reading
Discrete (off/on) output inductive proximity sensors are used in a multitude of markets and industries. The number of inductive sensors sold each year is in the millions. With that many pieces being sold each year, one has to ask – how are all of these sensors being used? Their uses break down into 3 common applications. Continue reading
Capacitive sensors serve certainly a niche within the group of proximity sensors. This niche makes people overlook the most striking feature this technology provides us – remote detection of any liquid through glass or plastic walls. Well, on the first look that does not sound too exciting and I agree, as long as you have not been tasked to specify a sensor to accomplish this very job. Continue reading
Photoelectric sensors have solved numerous industrial applications over the years. There are basically three different sensing modes. The first is diffuse or reflex mode, next is retro reflective, which requires a reflector, and the third is through beam, transmitted or opposed. These field devices provide an excellent means of detecting target at a distance without contacting the object. All of the sensing modes are based on the sensor’s ability to detect a change in light reaching the sensor’s receiver. In this posting, we will review the diffuse or reflex photoelectric sensor.

Written by: Jeff Himes Selecting the correct inductive proximity sensor for an application can be an intimidating process. There are literally thousands of models available from various vendors so having a good starting point to narrow down the field is … Continue reading
In my previous post we saw the myriad of different applications capacitive technology is involved in. We will discuss today the underlying physical principles of these sensors. Continue reading
Over the last year I have been discussing IP rated products with people in various positions in the manufacturing world and I have encountered some false assumptions about IP67 protection. I want to quickly go over what an IP67 test actually is and then go into the assumptions I’ve seen. Continue reading
