Solid-state relay price Solid-state relay is a new contactless switching device composed of solid-state electronic components,It uses electronic components(Such as switching triode、Semiconductor devices such as bidirectional thyristor)Switching characteristics of,It can achieve the purpose of connecting and disconnecting the circuit without contact and spark,Therefore, it is also called“No contact switch”。Due to the variability of the automation industry，The price list for solid-state relays is not given below，If you want to buy the original authentic solid state relay you can buy on the Feng Ye Mall，The solid state relays they sell are all original and genuine。
HURODrop type high voltage current limiting fuse HURODrop type high voltage current limiting fuse is based on the current exceeds the specified value after a period of time，The melt melts with its own heat，Thus disconnecting the circuit；A current protector is made by using this principle。Fuses are widely used in high and low voltage distribution systems and control systems as well as electrical equipment，As a short circuit and overcurrent protector，It is one of the widely used protection devices。
HSKProduction of linear bearing products are：Normal form、Gap adjustment type、open-type、Elongated type and flange type。passISO-9002International quality certification。High precision、High stiffness、Low noise。HSKLinear bearingSame outer cylinder、The ball retainer is fixed with the buckle at both ends，Make the steel ball repeat the cycle on the rail surface without falling off。The outer cylinder is sufficiently heat treated to achieve a comparable hardness，To ensure the safety and longevity of exercise。The ball retainer is formed with a high tensile resin，Reduce noise and wear between ball and retainer。
Photoelectric sensorIt is a sensor using a 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 sensors generally consist of light sources、The optical path and the photoelectric element are composed of three parts。 Photoelectric sensor classification Standard type 1）Diffuse reflection type：General type or energy type (-8)，Focus type (-8-H)，With background suppression function type (-8-H) Photoelectric sensor Photoelectric sensor ，Functional type with background analysis (-8-HW) 2）Reflector pattern：General type (-6)，Function type with polarization filter (-54, -55)，With transparent body detection function (-54-G)，With foreground inhibition function type (-54-V) 3）Relative form 4）Groove profile 5）Optical fiber sensor：Plastic fiber type，Glass fiber type
nachiRadial ball bearing parameters The radial ball bearing is a universal design，Able to withstand loads of different sizes in high-speed motion。This type of rolling bearing is composed of a complete set of precision ball and cage and an inner and outer ring。The standard radial ball bearing has a deep groove structure,It can withstand radial loads and small axial loads from any upward direction.Radial ball bearings with large load capacity mainly bear radial loads。
Understanding Nanjing process rolling linear guide should be very clear，It has a small coefficient of friction、High positioning accuracy、Energy saving and suitable for high-speed movement and many other advantages，It has been widely used in many kinds of machines such as CNC machine tools。Reasonable selection of guide rail parameters，For ensuring machine accuracy、It is very important to prolong the life of guide rail and reduce the cost。 1、Type selection： The manufacturers of precision linear rolling guides are different，The types are also different。Japan’34The rolling linear guide produced by the company has automatic adjustment of four directions equal load integral!356type#Sum-and-separate type!36type#、Automatic adjustment radial type!56#And small adjustable type!656#And the newly developed special rolling linear guide rail for machine tools)6type。Experimental proof，)6Type guideway compared with roller guideway，Cutting tool wear is reduced about07*times， Table driving torque reduced0-/， And affect the

Resistance sensorIt is a kind of electrical parameter sensor with early application，There are many kinds of it，Very widely used，The basic principle is to convert the change of the measured physical quantity into the change of the resistance value corresponding to it，After the corresponding measurement circuit，Reflects the change being measured。 The resistance sensor is simple in structure、Good linearity and stability，And the corresponding measuring circuit can be composed of measuring force、manometry、weigh、Measuring displacement、Acceleration measurement、Measuring torque、Temperature measurement and other detection system，It has become one of the indispensable means to detect the production process and realize the production automation。Resistive sensors are mainly intelligent potentiometers、Strain gauge type and piezoresistive type sensor three。 one、First of all, the selection of resistive displacement sensor specifications should leave a margin，Generally, on the basis of the actual trip, choose a large specif
