Enumere 10 preguntas y respuestas comunes relacionadas con la aplicación de OPB741WZ en soluciones técnicas

  1. What is OPB741WZ?

    • OPB741WZ is a reflective object sensor module that consists of an infrared LED and a phototransistor, used for detecting the presence or absence of an object.

  2. How does OPB741WZ work?

    • The infrared LED emits light, which is then reflected off an object and detected by the phototransistor. When the light is reflected back, it triggers the sensor to indicate the presence of the object.

  3. What are the typical applications of OPB741WZ?

    • OPB741WZ is commonly used in applications such as industrial automation, robotics, assembly line monitoring, and object detection in machinery.

  4. What is the operating voltage range for OPB741WZ?

    • The operating voltage range for OPB741WZ is typically between 4.5V to 5.5V.

  5. What is the sensing distance of OPB741WZ?

    • The sensing distance of OPB741WZ is approximately 0.2 inches to 0.4 inches (5mm to 10mm), depending on the reflectivity of the object.

  6. Can OPB741WZ be used for detecting transparent objects?

    • No, OPB741WZ may not be suitable for detecting transparent objects as they may not reflect enough infrared light to trigger the sensor.

  7. Is OPB741WZ sensitive to ambient light?

    • OPB741WZ is designed to minimize the effects of ambient light, but it may still be affected in extremely bright environments.
