Optical sensors are components commonly used in the automation industry. Specifically, the OPB740W series sensor is a reflective Analog Output optical sensor designed to detect the presence of an object in a designated region. This type of sensor is ideal for use in a variety of automation processes as it is effortless to install and highly reliable. In terms of practical application, the OPB740W series is well suited for applications such as position and level sensing, automatic door and window open and closing, printing processes, sorting, labelling, and packaging automation. Additionally, the sensor can also be used for detection of part presence in assembly lines for automatic feeder, cutting, loading and packing processes. The OPB740W series is a popular choice for optical sensing due to its long operating life, reliable performance, and complete protection against electrical interference. This series of sensor utilizes the reflective operating principle, meaning that the automatic sensing mechanism is based on the light reflection from the detected object. In its simplest form, the sensor consists of an IRED (Infrared Emitting Diode) emitting light and a photo-sensitive element detecting the reflection. When an object approaches the sensing area, some light from the IRED is reflected on the object and is detected by the photo-sensitive element. This provides a return signal response to the triggering voltage applied to the IRED, activating the output signal. The use of intensified LED (Light-Emitting Diode) flooding technology coupled with mechanical design improvements makes the OPB740W series one of the more reliable reflective Analog Output optical sensors currently available on the market. The integrated LED light source ensures the unit is always protected from external electrical influences which could have an adverse effect on the sensor’s performance. Furthermore, the integrated LED’s are heat and current protected to ensure a longer life expectancy while providing superior detection accuracy.Nevertheless, with any Optical Sensor, it is important to bear in mind that the accuracy of the detection is heavily dependent on the distance between the object and the detection area of the sensor. As the distance increases, the detector’s accuracy decreases. As such, it is important to select the correct model from the OPB740W series to ensure a precise detection range for your particular application. In summary, the OPB740W Series Optical Sensor is a suitable choice for applications requiring a reliable, long life tactile sensing solution with an Analog Output. By utilizing the reflective operating principle, this series of sensor utilizes reflected light from an object which may be invisible or difficult to detect with other sensing technologies. It is a safe and reliable option for a variety of applications and its highly reliable construction makes it an ideal choice for many automation processes.
