What are Photoelectric Sensors?

Posted by Michelle Szemanski on Jul 29, 2016 8:21:02 AM

Photoelectric sensors detect changes in light, consisting of a light source, receiver, a signal convertor, and an amplifier. The receiver (a phototransistor) reads incoming light to confirm that it comes from the sensor’s own lighting component (usually LED). When confirmed, the sensor triggers a pre-defined response.

From this simple concept, photoelectric sensors are incredibly useful for a broad range of industrial safety and automation processes. Seven sensing modes cover the majority of sensing applications, each addressing unique challenges in detecting photoelectric variation.

What is the PAC (Programmable Automation Controller)?

Posted by Anthony Gioia on Jun 27, 2016 3:00:40 PM

PACs are programmable automation controllers. They are digital computers that hold and execute embedded programs. These are seen in many different types of electromechanical processes and usually control the machinery in factories.

This name is very similar to PLC (programmable logic controllers), which we are very accustomed to in automation. PACs are relatively new to the market and PLCs have been around since the 1960s. The arrival of these new controllers begs the question: “How are they different?”

Easy Encoder Guide – Part 1: Rotary Encoders

Posted by Dave Gazda on Feb 12, 2016 10:12:25 AM

Many motion systems require the use of an encoder to determine position, speed or direction.  But with all the different variations and types of encoders on the market, the designer or engineer may have a hard time choosing the correct fit for the application.  The purpose of this guide is to help explain the different types of encoders and where each type is applied in typical motion applications.  So let us start with the basics to get the most out of your applications: incremental vs. absolute encoders.
