Introduction

Photoelectric sensors, also known as optical sensors, are simple devices used to detect physical presence of objects or processes, and to measure a variety of parameters such as position, distance, velocity, acceleration, force or pressure. There are three major types of optical sensors; the first being industrial photoelectric sensors, the second being photo detectors, and the third being photo reflective sensors. This article will focus on the GRTE18S-P2347, an industrial photoelectric sensor and examine its application field and working principle.

Application Field

The GRTE18S-P2347 is a high frequency, compact, industrial photoelectric sensor that is well-suited for many different types of applications. Common applications include the detection of presence of objects, such as a conveyor belt with small objects, detection of objects on a conveyor line, and detection of reflected light. It is also well-suited for controlling the direction of a robotic arm, which requires precise detection of objects and could also be used for receiving signals from remote locations. In addition, it is used for line-of-sight sensing, such as in barcode readers, and can be used in industrial automation, automotive inspection systems, security systems, and medical equipment as well.

Working Principle

The GRTE18S-P2347 is based on a physical property known as photoelectric effect. This effect was first discovered by physicist Heinrich Hertz in the late 19th century, and involves the illumination of a photosensitive material with electromagnetic radiation. When this radiation hits the material, electrons in the material become excited, causing the material to emit electrons, which can be collected and measured. This principle is used in the GRTE18S-P2347, which is composed of a light-emitting diode (LED) that produces a beam of visible or infrared light, and also a photosensitive element which is used to detect the light. When a portion of the beam is reflected back, the reflected light is detected by the photosensitive element, which signals the controller, producing an electrical output. This output can then be used to control a variety of electronic components or machines.

Conclusion

The GRTE18S-P2347 is a powerful, industrial photoelectric sensor suited for use in many types of applications. It operates based on the concept of photoelectric effect, where photons are used to excite electrons in a material. This in turn produces a measurable output that can be used to control a variety of electronic components or machines. The sensor is very useful in industrial automation, medical equipment, and security systems, as well as line-of-sight sensing such as in barcode readers.
