Walk into any die shop in the US and nine out of ten times, we discover diffuse reflective sensors being used to detect a large part or a small part exiting a die. Many people have success using this methodology, … Continue reading
Going about our hectic daily lives, we tend to just take the modern cycle of innovation for granted. But when we stop to think about it, the changes we have seen in the products we buy are astonishing. This is … Continue reading
In one of my previous post we covered “How do I wire my 3-wire sensors“. This topic has had a lot of interest so I thought to myself, this would be a great opportunity to add to that subject and … Continue reading
When the topic of welding comes up we know that our application is going to be more challenging for sensor selection. Today’s weld cells typically found in tier 1 and tier 2 automotive plants are known to have hostile environments … Continue reading
In my last post (We Don’t Make Axes Out of Bronze Anymore) we discussed the evolution of technologies which brought up the question, can a prox always replace a limit switch? Not always. Note that most proxes cannot directly switch … Continue reading
Every technology commonly in use today exists for a reason. Technologies have life cycles: they are invented out of necessity and are often widely used as the best available solution to a given technical problem. For example, at one time … Continue reading
Fundamental application problem: Inductive prox sensor is latching on (or…failing to turn on) The prox sensor gap is set to turn on when the target approaches, but it does not turn off when the target recedes (latching on) The prox … Continue reading
If someone says proximity sensor, what is the first thing that comes to mind? My guess is inductive and justly so because they are the most used sensor in automation today. There are other sensing technologies that use the term … Continue reading
Sensors in welding cells are subject to failure because, although they are intended to be non-contact devices, they tend to be located directly in the middle of the welding process. Conditions such as damage by direct mechanical impact, erosion by … Continue reading
