Through Beam Photo Sensors

Photo Sensor - Through Beam  The PS-LTB and MTB line of through-beam sensors can be ordered with a micro spot or a standard-size light beam. This makes it easy to select the best photo sensor for your application. Through Beam, sensors are very accurate, have a long sensing range, and are not affected by the object's color.  A beam of light is sent from the Transmitter to the Receiver. When the light is blocked by an object, the sensor switches states and opens or closes a switch.  The standard beam sensor is good for larger objects or porous objects. The large beam would not work as well for smaller objects, since the light could pass around the parts being detected and trigger the receiver.  The Micro Beam Photo Sensors are perfect for detecting smaller parts The small light beam is also good for counting parts that are close together and for precise position sensing. They have a visible laser light that makes it easy to align the sensors and focus on the object being detected.
