A Look into Factor 1 Proximity Sensors

A Look into Factor 1 Proximity Sensors

Inductive proximity sensors are suitable for many applications. Selecting models with factor 1 capability makes them even easier to deploy for sensing targets of varying metals. Andrew Waugh, Product Manager for Sensor and Safety products at AutomationDirect, authored an article for the May 2019 issue of Design World titled A Look into Factor 1 Proximity ... Read More
 
Wide and Narrow Views of Position Sensors

Wide and Narrow Views of Position Sensors

Andrew Waugh, Product Manager, Sensor and Safety Products at AutomationDirect.com, wrote an article for the September 2018 issue of Design World titled Wide and Narrow Views of Position Sensors, here’s a summary.  Limit switches, photoelectric switches and laser sensors all provide position sensing, but depending on the application some shine and reflect better. Waugh points ... Read More
 
What Is a Proximity Sensor? | AutomationDirect

What Is a Proximity Sensor? | AutomationDirect

What is a Proximity Sensor? Proximity sensors allow non-contact detection of objects. In particular the presence of parts and/or machine elements for the purpose of counting, indexing, verification, end-of-stroke or travel, determining orientation, and many other common automation tasks. They are used in many industries, including manufacturing, robotics, semiconductor, etc. Selection Criteria There are several types of proximity ... Read More

How to Specify Fiber Optic Sensors

How to Specify Fiber Optic Sensors

Fiber optic sensors work well in tight spots and in applications with a high degree of electrical noise, but care must be taken when specifying these critical components.
 
Beam Testing at Portland State

Beam Testing at Portland State

For their undergraduate senior capstone project, a team of Mechanical Engineering students at Portland State University (PSU) recently designed an electronic system upgrade for the control system of a 100-year-old beam testing machine. Using a range of AutomationDirect parts, the purpose of the project was to make the operator experience comparable to modern machines.

AutomationDirect’s AcuAmp® line of power products now includes the CTF series 5A secondary current transformers.  Designed for applications such as ammeters, wattmeters, panel meters, instrumentation, and energy management systems, these current transformers offer a compact, cost-effective means of measuring primary current.
 
Specifying Fiber Optic Sensors

Specifying Fiber Optic Sensors

Part presence sensing is a critical part of automation. A controller must often sense a part is present in a fixture, or sense the part position on a conveyor, to make logic decisions such as run, stop, etc. Presence sensor types include photoelectric, inductive, capacitive and others—and this abundance of choices can complicate specifying the ...

Distance Measuring | Automation Notes

Distance Measuring | Automation Notes

Object detection is sensing if an object is in proximity or not – that’s it, you get an ON or an OFF signal. A more advanced object detection function involves measuring the actual distance of an object from the sensing point. Ultrasonic sensors and laser distance sensors are commonly used to measure how far away ... Read More
 
Object Detection | Automation Notes

Object Detection | Automation Notes

A common function of a control system is detecting the presence of an object. Whether you are detecting the presence of an object passing by on a conveyor, the closure of a gate or the position of a machine part as it goes through its motions, object detection is a staple of the automation industry. There are ...
