introduction：We all know that with the development of science，Photoelectric sensors are also increasingly inseparable from our lives。Photoelectric sensor is a sensor using photoelectric element as a detection element。It first converts the measured change into a change in the light signal，The light signal is then further converted into an electrical signal with the help of a photoelectric element。Photoelectric sensorGeneral light source、The optical path and the photoelectric element are composed of three parts。 Structural analysis： Photoelectric sensors usually consist of three parts，They are respectively：transmitter、Receiver and detection circuit。 The transmitter has a calibration lens，Focus the light towards the receiver，A receiver outlet cable connects the unit to a vacuum tube amplifier。Inside the metal cylinder is a small incandescent lamp as a light source，These small but sturdy incandescent light sensors were the prototype of todays photoelectric sensors。

introduction：HUROFast fuse selection A quick fuse is a kind of fuse，Fast fuses are mainly used for short-circuit protection of semiconductor rectifier elements or rectifier devices。The overload capacity of semiconductor components is very low。It can only withstand a large overload current for a very short time，Therefore, the short-circuit protection is required to have the ability to fuse quickly。The structure of the fast fuse is basically the same as that of the packed closed fuse，But the melt material and shape are different，Its made of silverVMelt with variable cross-section in a deep groove。 Type selection：

introduction：HUROClassification of fast fuses When it comes to fast fuses, I believe everyone is familiar with them，It is very common in our life。HUROThe fast fuse is when the current exceeds the specified value，Fusing the melt with its own heat，An electrical appliance that breaks a circuit。 Common species: Plug-in fuse： It is often used in380VAnd below the voltage level of the line end，As a distribution branch or electrical equipment short circuit protection。 Screw type fuse： The upper end of the melt is covered with a fuse indicator，Once the melt is blown，Indicator will pop up soon，It can be seen through the glass holes in the porcelain cap，It is often used in machine tool electrical control equipment。Screw type fuse。The breaking current is large，Available for voltage levels500VAnd below、Current class200AThe following circuit，Short-circuit protection。
