introduction：Yueqing rodless cylinder The concept of cylinder rodless originatedorigaPut forward and practice，origaWith their own advanced technology research and development strength，Open the door to the rodless era。Rodless cylinder，Saves space for device integration。Rodless cylinder refers to the use of pistons directly or indirectly connected to the external actuator，And make it follow the piston to achieve reciprocating movement of the cylinder。The big advantage of this type of cylinder is that it saves installation space，Divided into magnetic couple rodless cylinder（Magnetic cylinder）With mechanical rodless cylinders。

introduction：Photoelectric switchThe important function is to be able to handle changes in the intensity of light：optically，Change the beam in the middle of the propagating medium；Using light to reflect objects；Make the beam return instantaneously after a long distance。The photoelectric switch is made by the transmitter、The receiver and the detection circuit are composed of three parts。The transmitter aims a beam at the target，The emitted light usually comes from a light-emitting diode（LED）And laser diode。The beam is emitted without interruption，Or change the pulse width。The radiation intensity of the pulse-modulated beam is selected several times during emission，Run toward the goal not indirectly。The receiver consists of a photodiode or a phototriode。In front of the receiver，Equipped with optical elements such as lenses and apertures。On the back is the detection circuit，It can filter out the effective signal and apply the signal。 Photoelectric switch sensor type：The photoelectric switch can be divided into beam type、Dif

introduction：Load cell elastomer action Load cellThe function of an elastomer is to transfer external forces，It must have the same amount of force at the time，deformational，Because the strain gauge is glued to the elastomer，The deformation of the elastomer is the deformation of the strain gauge；At the same time, it must have a reset，When the external forces disappear，Can reset automatically。Elastomer materials are usually selected from a variety of metals，Mainly aluminum alloy、Stainless steel and alloy steel, etc。

introduction：Photoelectric sensorGenerally by the processing path and processing elements2 Partial composition。Its basic principle is based on the photoelectric effect，The measured change is converted into a change in the optical signal，The non-electrical signal is then further converted into an electrical signal with the help of a photoelectric element。The photoelectric effect is when light shines on an object，You can think of it as a stream of photons with a certain energy bombarding this object，The photon energy is then transferred to the electron，And all the energy of a photon is absorbed by an electron at once，When an electron receives the energy of a photon, its state changes，Thus, the object irradiated by light produces the corresponding electrical effect。 The photoelectric effect is usually divided into3 class： （1）The phenomenon that electrons can escape from the surface of an object under the action of light is called the external photoelectric effect，Such as photocell、Photomultiplier tube, etc； （2）The phenomeno

introduction：Angular displacement sensor（potentiometer）Definition of Angle sensor（potentiometer）Its a tunable electronic component, It moves on the resistor by moving contacts, Thus obtained with the Angle sensor（potentiometer）Input voltage and moving contact displacement(OR-angle) Voltage output into a certain relationship。 Angle sensor（potentiometer）The basic installation mode： Pin type： In general use, Can be Angle sensor（potentiometer）Plug directly into the printed circuit board and wave weld。 Sleeve mounting： When designing structures that need to withstand severe mechanical vibrations and shocks, Angle sensor can be mounted with shaft sleeve（potentiometer）。Use the bushing nut and washer to place the Angle sensor（potentiometer）Fixed to the bottom plate。
