Slot type photoelectric switch is actually a kind of opposite-beam photoelectric switch, also known as U-shaped photoelectric switch. It is an infrared induction photoelectric product. It is composed of infrared transmitting tube and infrared receiving tube. The strength of the receiving model and the distance of the received signal, with light as the medium, are received and converted by the infrared light between the light-emitting body and the light-receiving body, and the position of the object is detected.
The slot-type photoelectric switch is also non-contact like the proximity switch, which is less restricted by the detection body and has a long detection distance. It can perform long-distance detection (tens of meters) with high detection accuracy and can detect small objects. The application is very extensive.
Compared with the proximity switch, the photoelectric switch has a very long detection distance and is non-contact, so it will not damage the detection object and is not affected by the detection object.
Like other proximity switches, the slot-type photoelectric switch has no mechanical movement, so it can detect objects moving at high speed.
Selection points of slot photoelectric switch (optical coupler):
1. The slot width, the detection object needs to pass through the slot of the slot optocoupler to block the infrared light, so the slot width of the photoelectric sensor should be wider than the detection object, and there should be a certain margin for easy installation.
2. Grooved groove photoelectric appearance: with fixing hole and with fixing hole, please choose according to the actual situation.
3. Installation position: When installing the grooved photoelectricity, the outer diameter of the detection sprocket should exceed the detection point by 1-2mm. This can effectively block the light.
4. Speed: If there is a high-speed application, it is necessary to pay attention to whether the switching frequency of the slot-type optoelectronics meets the requirements for use.
5. Use environment: If it is used in the environment of strong light and natural light, you should pay attention to choosing a sensor that resists strong light interference. ECOTTER trough photoelectric has been tested to resist strong light interference above 20000Lux.
Mobile phones and earphones have become necessities in our lives. How many people feel restless when they don`t have a mobile phone around. The mobile phone gives us a great sense of security to a certain extent, and its additional earphones also have such a function. . Wear headphones when you don`t want to talk; when you don`t want to listen to others, you wear headphones; when you don`t want to be harassed in an unfamiliar environment, you can play your favorite songs, be happy or sad, and enjoy your little universe most comfortable. There are now a variety of earphones on the market for people to choose from. From the original wired earphones to the current wireless Bluetooth earphones, they are more and more in line with people's requirements, and the sound quality and noise reduction are also constantly improving.
If you want to get a sports headset (sports scene) or a true wireless tws true wireless Bluetooth headset, what you expect from him is that it has the ability to withstand the test of different environments, wear it steadily, and have a long battery life, or it may be out of the street. Appearance, excellent sound quality, stable connection, friends who have certain requirements for sound quality and low requirements for noise reduction. You can take a look our earbuds.
