Smart vision sensors incorporate on-board machine learning, empowering users to deploy them in common applications, without the cost and complexity of traditional products. Common photoelectric (PE) sensors are the most basic type of “vision” device, but traditionally it has required much more advanced technology to capture and analyze actual images for advanced detection. In an…

Basic Sensors - PLC Fundamentals
For a PLC to monitor and in turn control its application variables, there must be a way for it to sense its surroundings. In today’s industrial realm, there are a huge variety of electrical sensors that provide the input data (position, distance, level, flow, etc.) that control systems need. These basic sensors can be broken…
