Opto Reflective Sensor

They can be used to provide real time information in a manufacturing setting in order to keep processes running smoothly.

Opto reflective sensor.

The author s prototype is shown in fig. Reflective sensors reflective sensors are composed by leds and photoreceivers phototransistors or photodiodes and are used on distance meters proximity sensors and object detectors. These optical sensors work in a similar way to the slotted opto sensor but rely on infra red light reflected from an object e g. An optical sensor can measure the changes from one or several light beams.

They are a non contact type of sensor often used in the automation industry. Photoelectric sensors detect photo optical workpieces. Reflective optical sensors are photoelectrical sensors that are used to detect the presence or absence of objects or measure the distance to those objects. Optical sensors rohm s optical sensors include high sensitivity high reliability phototransistors infrared light emitting diodes transmission type photointerruptors and reflective type photointerruptors.

That means when the phototransistor is not getting reflected ir rays output remains in logic 0 low and when it gets reflected light output turns to logic 1 high. The trigger reacts to a change in the signal within the light sensor. These days opto reflective sensor is used in various project like proximity sensing position detector robotics etc. The current produced by the sensor is even smaller than the output currents of the.

Omron provides many varieties of sensor including diffuse reflective through beam retro reflective and distance settable sensors as well as sensors with either built in or separate amplifiers and fiber units. A sheet of paper in a printer placed about 2mm to 8mm from the sensor to produce an output. This is often connected to an electrical trigger. 6 346 2 71000 cut tape ct alternate packaging not for new designs 19 7 50cm 1 6 reflective non metallic surface mount 400ma.

Thus we had posted a diy project with working range of 2mm to 10mm. Sensors transducers optical sensors reflective analog output are in stock at digikey. 34 039 digi reel 1.
