Photoelectric Sensors

<p>The photoelectric sensors exploit the photoelectric properties of light. Whenever light enters the transparent bulb of a photo electric cell, it knocks out some electrons from the negatively charged plate (connected to the negative terminal of the battery) and is swept across the opposite terminals.</p>

<p>This flow of electrons constitutes electric current through of the order of micro amperes and is used to detect light in its applications, aptly termed as Photo electric Sensors.</p>

<p>There are four sensing types of Photo electric Sensors namely diffuse reflective, thru-beam, adjustable range reflective and retro-reflective.</p>

<p>• Diffuse Reflective is for short distances of 100 to 800 mm and has a 2mm diametric beam spot.</p>

<p>• Thru-beam is available in up to 15m; detecting distance models have the longest range.</p>

<p>• Adjustable Range Reflective is up to 300m detecting distance.</p>

<p>• Retro-Reflective is specialised model for transparent object detection.</p>

<p>All types are available with NPN or PNP transistor outputs.</p>

<p><b>Compact Photo electric Sensors</b></p>

<p>As the name suggests, these sensors are compact in size measuring as small as the size of your shirt’s button. These sensors, when coupled with a high performance circuitry, can detect small height differences or detect transparent objects and also sense subtle differences in colour.</p>
