Optical Sensors: Photoelectric, Industrial

Optical sensors are electronic measurement devices used to detect, measure, and convert light signals into electric signals. Various types of optical sensors, such as photoelectric, infrared, and laser, are available. Photoelectric and industrial optical sensors in particular are used in a wide array of industrial applications. This article will explain the application field and working principle of the PA18CAB20NASA, an industrial optical sensor.

Applications of PA18CAB20NASA

The PA18CAB20NASA is an industrial optical sensor for measuring various parameters in various types of equipment and systems. It is a self-contained device capable of measuring light and dark without the need of external components. It can be used in applications such as detecting when doors are open, measuring the presence of obstacles, detecting temperature and motion, and sensing the presence of objects. Moreover, it can be used in more general applications such as sensing the presence of people and animals, monitoring liquid levels, and indicating the presence of abnormalities in industrial settings.

Working Principle

The PA18CAB20NASA uses a semiconductor to process the light signals and convert them into electric signals. The sensing element consists of an emitter, a receiver, and a detector. The emitter sends out light signals which are picked up by the receiver. The detector then processes the signals and sends them to the output. The output signal can be used to control different processes, such as turning a machine on or off.

The PA18CAB20NASA has a wide dynamic range, meaning it can detect light and dark conditions between 0 and 10V, and is also capable of simultaneously measuring two channels of data. This makes it an ideal choice for applications that require high accuracy and reliability. The accuracy of the PA18CAB20NASA is 0.1%. Additionally, it is highly resistant to vibration, meaning it can be used in rough working environments.

Conclusion

The PA18CAB20NASA is an industrial optical sensor designed for use in various applications. It is a self-contained device that uses a semiconductor to process and convert light signals into electric signals. Its wide dynamic range and accuracy make it highly reliable and suitable for various industrial applications, including detecting open doors, measuring motion, and sensing the presence of people or animals.
