contrinexProximity switch contrinexProximity switch is a position switch that can be operated without direct mechanical contact with moving parts，When the object approaches the sensing surface of the switch to the operating distance，No mechanical contact or pressure is required to make the switch operate，To drive DC electrical appliances or to the computer（plc)The device provides control instructions。As an indispensable part of machinery，The following is a small edition of Feng Ye to take you to understand its performance and characteristics！
Original bindingcontrinexProximity switch Proximity switch is also known as contactless proximity switch，It is an ideal electronic switching sensor。If you want to buy authentic SwisscontrinexProximity switch you can buy on the Feng Ye mall，Because the proximity switches they sell are a large stock of original and genuine products。 Original bindingcontrinexProximity switch wiring diagram
leserPrice of safety valves leserThe safety valve is in a normally closed state under the action of external force，When the medium pressure in the equipment or pipe rises beyond the specified value，A special valve that prevents the pressure of the medium in the pipe or equipment from exceeding specified values by discharging the medium outside the system。Safety valves belong to automatic valves，Mainly used in boilers、Pressure vessels and pipes，Control pressure does not exceed the specified value，It plays an important role in protecting personal safety and equipment operation。

Schneider Electric Limited(Schneider Electric SA )Is the world500One of the strong enterprises， 1836It was founded by the Schneider Brothers。It is headquartered in Ruet, France。 SchneiderElectric is a global leader in energy efficiency management，for100Energy and infrastructure in multiple countries、industry、Data centers and networks、Total solutions for the building and residential markets，It also has strong market capabilities in the field of residential applications。2012Fiscal year，Schneiders total revenue worldwide reached240Billions of euros，in100Several countries have more than140，000staff。 Schneider products true and false how to distinguish？ from2007from，Schneider Electric has started using anti-counterfeiting labels on low-voltage distribution and industrial control products sold in the Chinese market，To protect the authenticity of the product。This new anti-counterfeiting trademark can provide customers with the identification of low-voltage power distribution and industrial control products。
TimkenAngular contact ball bearingDesigned to carry combined radial and axial loads。Single row bearings can handle high axial loads from one direction。In order to achieve large performance some single row bearings are often designed to be paired。biserialConradBearings can withstand axial loads in both directions。 Size range 1、single-row：Inside diameter10 mm – 150 mm (0.3937 in. – 5.9055 in.) 2、biserial：Inside diameter12 mm – 150 mm (0.4724 in. – 5.9055 in.) Design characteristic 1.Angular contact bearings Special geometry of the raceway and shoulder provides the ball contact Angle to carry higher axial loads。 2.Options include special lubricants、Material of cage、Pre-loaded and corrosion-resistant coating。

Variable frequency motor can be adjustable arbitrarily within its speed range，And the motor will not be damaged，Most of the general domestic ordinary motors can only beAC380V/50HZRun under conditions，General electric machineCan be used down or up frequency，But not too wide，Otherwise, the electric machine will heat up and even burn out。 Common fan internal cooling fan and fan movement use the same line，And the frequency conversion fan these two are separate。Therefore, when the frequency conversion of the ordinary fan is too low，It could burn up from overheating。 Variable frequency motor due to withstand high frequency magnetic field，Therefore, the insulation level is higher than that of ordinary motors，In principle, ordinary motors cannot be driven by frequency converters，But in practice to save money，In many occasions where speed regulation is required, ordinary motors are used instead of variable frequency motors，However, the speed regulation accuracy of ordinary motors is not high，In-process fan、Th
