Non-amplified photomicrosensors detects the presence or absence of objects

Omron's non-amplified photomicrosensors, more commonly known as photointerrupters or optical switches, are now available from Mouser stock. They are infrared emitter / detector pairs contained in a compact single housing designed to detect the presence or absence of objects. Omron offers hundreds of variations on the basic photointerrupter. Please see the Omron Whitepaper for reference to focus on the type, body shape and connection style best suited for specific design applications. The transmissive photomicrosensor incorporates an emitter and detector that face each other. When an object is positioned between the emitter and detector, the optical beam is interrupted, causing the detector to react to this change in optical energy. The reflective photomicrosensor incorporates an emitter and detector that face outward. When an object comes into range, the optical beam sent out by the emitter will reflect off the object and back towards the detector, causing the detector to react to this change in optical energy. Omron uses a silicon potting structure on the LEDs inside its photomicrosensors. This reduces any mechanical stress applied to the LED and thus strengthens the physical integrity of the LED chip. The end result is an LED that maintains higher brightness for a longer period of time. A wide range of non-amplified photomicrosensor products is offered giving the choice of transmissive, reflective or actuator types with different slots widths, sensing distances, configurations, and mounting styles.
