OMRON's Creative Lab | Surface Mount Photomicrosensor

OMRON Photomicrosensors are compact optical sensors designed for high-reliability object or position detection. They are available in two main types: transmissive and reflective. Transmissive sensors detect objects by breaking a light beam, while reflective sensors detect objects by sensing reflected light. OMRON Photomicrosensors offer significant advantages in size and efficiency, making them indispensable in modern manufacturing and consumer electronics. The versatility and reliability make them a ideal for a wide range of applications such as door closures, ATMs, 3D printers, and smart gas meters.

    00:00:06 hello everyone my name is Roland hoo product manager for sensors at rran electronic components today I would like to discuss ran surface mount photo micro sensors photo micro sensors also known as photo interrupts are compact Optical sensors that sense objects or object positions with an optical beam they are commonly used in consumer equipment and Commercial devices which re require High

    00:00:31 reliability photo micro sensors are superior in durability sensing position accuracy and response speed by employing non-c cont switching through the utilization of an optical beam omran offers leaded connector and pre-wired models but today we will be focusing specifically on the surface mount photo micro sensors one notable advantage of surface mount photo micro sensors is

    00:00:57 their ability to eliminate the need for manual soldering after after the Reflow process this not only streamlines the manufacturing process by eliminating the need for hand soldering but also enhances overall efficiency also compared to Conventional lead type models the maximum volum ratio is reduced by 65% photo micro sensors are categorized

    00:01:23 into two main groups transmissive types also known as slotted types shown on the left and reflective types shown here here on the right the LED sends out an infrared light beam that is then picked up by the detector to close the circuit for the slotted type the circuit is closed until the beam is blocked by the object which opens the circuit for reflective types the circuit is open

    00:01:46 until the beam is reflected off of the object to close the circuit they also come with either a photo transistor output where the condition to turn the sensor on or off is adjustable using an external circuit or photo IC output where the condition to turn the sensor on or off is fixed with an internal circuit now let's go over the two sensing types offered first we have the

    00:02:10 transmissive types also referred to as slotted type models these sensors detect objects by passing the target object through the emitted Light Beam from the aperture the emitter is located across from the receiver creating a slot detection occurs when an object breaks the light beam between the emitter and reer receiver the next sensing method are the

    00:02:33 reflective photo micro sensors these detect presence or absence of objects by sensing the reflected light on the object they can also detect marked objects such as printed marks on paper or labels on packaging materials now let's discuss some of the applications where photo micro sensors can be used in first we have presence detection for

    00:02:56 applications that require frequent switching and high reliability here you see the slotted sensor that is capable of detecting various door closures or locking mechanisms ranging from doors on Amusement equipment Lids on vacuum cleaners and medication cabinets these applications can replace the use of micro switches with photo micro

    00:03:21 sensors this can increase the longevity of the products by eliminating contact deterioration or corrosion next we have position detection some examples include card position detection or build detection on ATM machines detecting position of filament and 3D printers to ensure proper alignment and coffee machines detecting the amount of coffee grounds

    00:03:45 left in the machine here we have rotation detection that can be used in smart gas meters to monitor usage monitoring the rotation of mobile cameras and various dials in home appliances such as laundry machines thank you so much for watching to learn more about these sensors and other products that noron has to offer please visit our website at components.
