Practical Tips and Techniques
Proximity (Capacitive, Inductive), Photo electric (Thru beam, Retro Reflective, Diffuse), Ultrasonic, etc. Sensors can be either discrete (On/Off) or Analog outputs.
Accelerate Learning … Accelerate Machines… Accelerate Knowledge… ACC Automation It is a good time to be in the automation business. Technologies are merging and communicating like never before. What was impossible is now possible for the industrial plant floor. We are looking forward to the New Year and new possibilities for implementing your control solution. … Read more
Signal conditioners are used with analog current and voltage signals. They have the ability to change your input analog signal to another output analog signal. As an example, we can have 4-20mA analog input and change it to a 0-10VDC output signal so we can wire this into our PLC. Typically signal conditioners will also … Read more
An ultrasonic sensor (switch) is able to detect object presence without physical contact (limit switch). No physical contact means that the switch has no parts that will wear out. The life span of the sensor is increased with less maintenance. An ultrasonic sensor will use sound waves to detect objects. These sound waves are at … Read more
A proximity sensor (switch) is able to detect object presence without physical contact like a limit switch. No physical contact means that the switch has no parts that will wear out. The life span of the sensor is increased with less maintenance. A capacitive proximity sensor will detect ferrous and non-ferrous objects. The sensor works … Read more
We will now look at wiring an NPN and PNP inductive proximity sensor to the Click PLC. A proximity sensor (switch) is able to detect object presence without physical contact like a limit switch. No physical contact means that the switch has no parts that will wear out. The life span of the sensor is … Read more
ACC Automation We would like to take a few minutes and reflect on the past, current and future of ACC Automation. 2017 has been our best year yet thanks to you. Your questions, comments and suggestions have helped us to build the site that you see today. Thank you.
