Information

The photoelectric switch sensor is a kind of sensor, which converts the change of light intensity between the transmitting end and the receiving end into the change of current to achieve the purpose of detection. Since the output circuit and input circuit of the photoelectric switch sensor are electrically isolated (ie, electrically insulated), it can be used in many occasions. The new generation of photoelectric switch sensor devices manufactured by using integrated circuit technology and SMT surface mounting technology have intelligent functions such as delay, widening, external synchronization, anti-interference, high reliability, stable working area and self-diagnosis. This novel photoelectric switch sensor is an active photoelectric detection system electronic switch that uses pulse modulation. The cold light source it uses includes infrared light, red light, green light, and blue light. It can be contactless and damage-free. Quickly and control the state and action of various solid, liquid, transparent, black, soft, smoke and other substances. It has the advantages of small size, multiple functions, long life, high accuracy, fast response speed, long detection distance and strong resistance to optical, electrical, and magnetic interference.

The photoelectric switch sensor has been used as level detection, liquid level control, product counting, width discrimination, speed detection, fixed-length cutting, hole recognition, signal delay, automatic door sensing, color mark detection, punching and shearing machine And security protection and many other fields. In addition, the use of infrared concealment can also be used as an anti-theft warning in banks, warehouses, shops, offices and other occasions where it is needed.
The commonly used infrared photoelectric switch sensor uses the principle of reflection of the near-infrared beam by the object. The synchronization circuit senses the intensity of the reflected light and detects the presence or absence of the object to achieve its function. The photoelectric sensor first sends out the infrared beam to reach or penetrate The infrared beam is reflected by the object or mirror, and the photoelectric sensor receives the reflected beam, and judges the existence of the object according to the strength of the beam. There are also many types of infrared photoelectric switch sensors. Generally speaking, there are several main types such as retro-reflective photoelectric switch sensor, diffuse reflection type, slot type, through-beam type, and optical fiber type. The photoelectric switch sensor is included in the automatic selection of fast, easy and excellent.
Different photoelectric switch sensors are used in different occasions. For example, optical fiber type photoelectric switch sensors are often used in electromagnetic vibration feeders, and diffuse reflection type photoelectric switch sensors are often used in the supply of packaging film of intermittent packaging machines. Slot-type photoelectric switch sensors are often used in high-speed packaging machines.
