PA18CRD08PASA Application Field and Working Principle

Photoelectric sensors are used in many industries today due to their excellent sensing performance, and the PA18CRD08PASA photoelectric blocking type sensor is no exception. This advanced optical sensor is frequently used in a variety of industrial applications, including non-contact sensing, mechanical counting, and positional measurement. By understanding its application field and working principles, you will be better equipped to utilize this versatile tool for a variety of tasks.

Application Field of PA18CRD08PASA

The PA18CRD08PASA has a large application field due to its reliable measurement performance and high precision. Its main application can be classified in two major categories.

Non-Contact Sensing

Non-contact sensing applications can be widely found in industrial automation, robotic arms, and other manufacturing production lines. For example, the output of PA18CRD08PASA can be connected to a robotic arm, enabling it to recognize its relative positioning. This allows the robotic arm to move objects from place to place with precision and accuracy.

Mechanical Counting & Positional Measurement

The PA18CRD08PASA is often used in mechanical counting and positional measurement. It is most frequently used for counting applications, such as items on a production line or animals in a production barn. It can also be used for measuring distance, position, and displacement. By combining the output of the PA18CRD08PASA with the signal from another device, such as a counter or timer, more precise measurements can be made. For example, a timer can be set to measure the time between movements of two consecutive objects. By counting the number of objects that have passed the sensor during that period, the overall speed of the process can be determined.

Working Principle of PA18CRD08PASA

The PA18CRD08PASA utilizes photoelectric sensing principles to detect objects. A light emitting diode (LED) is mounted in the sensor housing and is directed at a special phototransistor. When an object is placed in the path of the LED\'s light beam, the phototransistor\'s electrical properties will change. This change will register as an output signal that can be used by other devices. The PA18CRD08PASA also utilizes a shield plate, which provides extra protection from external influences such as dust and noise. This reduces the possibility of false readings and false alarms. It also allows for easier wiring and setup.

Conclusion

The PA18CRD08PASA is a versatile and reliable photoelectric blocking type sensor that is used in many applications across a range of industries. Its most common uses include non-contact sensing, mechanical counting and position measurement. Its working principles rely on the sensing of objects using light and the reception of the output signal by a phototransistor. Lastly, its additional shield plate helps improve its reliability.
