Product Description YK Series Automobile Air Conditioning Pressure SwitchProduct DescriptionProduct FeaturesAdopt British pipe thread quick connector or copper tube (including capillary) welding connection structure, easy to install, can meet different needs.The shell adopts two installation methods: board mounting (with mounting ears) or wire mounting (no need for additional fixing), which can be selected by users.The sealed double insurance disc stainless steel sensor ensures that the switch connector is automatically and quickly disconnected under pressure, and cuts off the connection between the switch connector and the pressure in the system, ensuring that the system will not be damaged by accidentally turning on the switch to start the machine, which is particularly safe and reliable.The independent automatic disconnection and manual reset dual structure design greatly improves the safety and reliability of pressure protection.Typical appearance diagramWorking Principle When the pressure in the system is higher than the rated safety pressure, the pressure sensing disc in the sensor will be activated instantly, and the push rod will push the safety disc to the locked position. At the same time, the safety disc will push the switch to disconnect through the connecting guide rod. When the pressure decreases, the sensing disc will automatically reset. Since the safety disc is already in the locked position, it cannot automatically reset and the switch cannot be turned on. Only when the external button is pressed and the safety disc is forced to unlock and the switch connector is connected, can the system return to normal working state.Application This series of pressure switches is suitable for various air conditioning and refrigeration systems with special requirements for pressure protection, and a wide range of occasions for overpressure protection of various equipment and tool pressure systems. The pressure switch can be directly installed on the pipeline, or installed on the equipment panel according to the equipment requirements.Design parametersWorking pressure range: 145~800PSI (1~5.5MPa)Burst pressure: 5000PSIAmbient temperature: -30oC~+80oCSystem medium temperature: -50oC~+120oCElectrical specifications: Conventional electrical capacity 125VA at 24Vac, conventional electrical capacity 375VA at 120/240VacDielectric strength: AC700V/S between disconnected contacts, AC2000V/S between terminals and housingSafe withstand voltage: The pressure that the pressure controller can withstand without affecting the action setting value. Maximum working pressure rangeSafety pressure resistance145PSI(1MPa)~400PSI(2.75MPa)600PSI(4.1MPa)>400PSI(2.75MPa)800PSI(5.5MPa)Typical structure diagramElectrical schematic diagramProduct Parameters YK Series Single Cut Single Thrower Auto-reset Pressure Contro (YK-01H YK-02H YK-03H YK-01L YK-02L YK-03L Product Specifications Adopting Eng thread quick connector(copper flare connection)or brass tube welding fitting structure, flexibly setting, easy to use and no special need for mounting and fixing Plugging or wiring connection designed to customers choice SPST connection, normal open or normal close structure to customers choice Security and reliability by adopting fusion welding stainless steel pressure inductor and full air-tight connection Any pressure value within 3-800 PSI(0.02-55mpacan be made based on customers' requirement Pre-set pressure parameter before delivery allows direct use without resetting on the customers site Operating Principle The series of pressure control are made based on the theory that an inside reversible stainless steel motion diaphragm turns over when inducing certain pressure. The electric contact opens or closes with the leader when the diaphragm moves. The switch resets automatically when induced pressure reduces below rated value Application The series of pressure control are used to the high, low pressure protection of some refrigeration system like residential, commercial automobile air-conditioner and ice maker etc. It can also be used to hydraulic pressure and steam pressure control system of all kinds of air compressor, equipment or tool and agricultural machineProduct featuresAdopt quick joint of inch pipe thread or copper pipe welded structure, easy to use, flexible to install, no need of special installation and fixation;Insert type or wire type connection mode is available for users to choose at will;Single-pole single-throw switch mode, normally open switch contact structure; Welded sealed stainless steel pressure inductor with steel explosion-proof enclosure, safe and reliable; It can be manufactured within the pressure range of 1305PS~2610PSI(9~18MPa) according to the user's requirements. Before leaving the factory, the pressure parameters of the product have been set according to the requirements in the factory. There is no need to set any more, so it can be used directly.Installation InstructionsPackage and Shipping1.FedEX / DHL / UPS / TNT for samples,Door to door service;2.By sea for batch goods;3.Customs specifying freight forwarders or negotiable shipping methods;4.Delivery Time:20-25 Days for samples;30-35 Days for batch goods;5.Payment Terms:T/T,L/C at sight,D/P etc.FAQQ1.
