NA2-N28-C5 photoelectronic switches are highly versatile industrial sensors used to measure the presence/absence of an object, as well as its displacement, direction, and location. This type of device is also known as a photoelectric or optical sensor. It uses a beam of light to determine the presence of an object, its displacement, direction, or location.

This type of device consists of a light source, an optical device which directs the light, a transmitting/receiving optical head, and two electrical contacts. When an object interrupts the beam of light, the electrical contacts send a signal through the transmitter/receiver which is then sent to the control system.

These sensors can be used in a multitude of applications. In industrial automation, they are used to detect presence/absence and to measure speed. They are also used to ensure accurate positioning in assembly and machining applications. In medical and security applications, the sensors can provide precise measurements for movement, location, and direction.

NA2-N28-C5 photoelectric switches also have a wide range of applications in robotics. Robotics applications require sensors that can measure and detect precise movements with a high degree of accuracy and repeatability. These sensors are extremely reliable and accurate and can detect and measure a object\'s presence/absence, displacement, direction, and location.

The underlying principle of operation of photoelectric or optical sensors is that the light beam is modulated either electrically or mechanically and then detected by the optical head for the measurement of presence, displacement, direction, or location. The light source is typically a light-emitting diode (LED), and the detector can be either an LED or a phototransistor. Photodiodes are often used in combination with LED/phototransistors to increase the sensitivity of the sensor and to reduce the effects of noise.

The fundamental operation of these sensors is based on the photoelectric effect. When light incident on an object, the incident light will be partially reflected, partially absorbed and partially transmitted. However, when light is incident on an object, the light intensity changes proportional to the distance or displacement of the object. This change in light intensity can be detected by an optical head, and the output signal of the optical head is then used to determine the presence/absence, displacement, direction, or location of any object.

NA2-N28-C5 photoelectric switches are widely used in a variety of industrial, robotic, security, and medical applications. Their ability to detect presence/absence, displacement, direction, and location of an object with a high degree of accuracy and repeatability, coupled with their operational robustness and reliability, makes them an invaluable tool for both automation and manufacturing.
