About DEWO
Hello
Thank you for purchasing the service parts of electronic products, thanks! In order to protect your legal rights, remove your worries, Andover Electronic Technology Co., Ltd. of Dongguan City to you to make the following service commitment and when you need accordingly to you.
That since the purchase of Andover parts electronics products within 6 months from the date of, if you buy the product has any problem, you can choose a replacement.
If you need to consult with product related technical problems in the use of
You are welcome to call the service of electronic technology support line:
86-769-81732018/81732098 transfer engineering,
Provide professional solutions by our engineers.
Common considerations:
Detection switch
1, when the terminal is welded, if the load is applied on the terminal, because of the different conditions will be loose, deformation and electrical characteristics of the potential, please note that when using.
2, because when welding, water soluble flux to switch corrosion may, please avoid using.
3, on the condition of welding, please according to the actual conditions of mass production.
4, if the voltage of the following or current 100A DC3V following the use of, there will be contact with the bad, for the above situation, please confirm.
Power Supply
1, can not clean.
2. The product is designed and manufactured by the DC resistance load. Use of other loads (inductive load (L), capacitive load (C)), please confirm.
Press
1, please note that according to the type of switch to set the circuit set (set) the circuit set (the software set) into a combination of components does not produce false action.
2, attention can not be used in the temperature range near the upper and lower limits of long-term continuous use. Please note that the range of test in the use of various environmental conditions specified in the product specification.
Slide
1, in the use of temperature period and near the lower limit of continuous action, please note that should be based on each machine are confirmed using provisions if possible.
Rotation
1, please use the car for the purpose of using the specified switch. Did not specify a switch for the car, pay attention not to use.
2, use should pay attention to the amount of movement should be as close to the total number of mobile location.
Encoder
1. Please note that the mobile location can be used for the full amount of space in the beginning of the ON.
2, please note that the switch can not be used for the recovery of the mechanical parts of the mechanical part of the driving force.
Testing
1, the process of PCB overlap placed and move to send, please note not to the operating department to apply the lateral force.
2, especially the small, thin switch in the assembly parts of the installation process, please pay attention not to apply force.
Switch
1, the use of the printed circuit board and the recommended circuit board, due to the influence of thermal stress will be changed, so please make full confirmation of the welding conditions in advance.
Multi-function
1, due to the bending of the circuit board may cause the characteristics of the change, please consider the mode design and layout design.
Operating device
1, the use ratio of circuit board recommended thickness when the switch is installed, paste may float, please note.
Touch type:
2, if the dust in the use of the environment, dust will enter from the opening, resulting in contact failure and action, the design of the combined parts, please consider this point.
3, if the use of the switch of the machine around the material to produce corrosive gases, will have the potential to cause contact with the phenomenon, so please make full confirmation in advance
Special custom
1, custody method
Products:
1, products in the delivery of the state at room temperature, often wet, not subject to direct sunlight exposure, do not produce corrosive gas in the place of custody, self delivery within 6 months to the limit, please use as soon as possible.
2, Kaifeng to cut off with a polyethylene bag and outside, please keep in the same environment, and use as soon as possible.
3, please do not place too much.
Sliding switch
Precautions when using
1, when the terminal is welded, please note that if the terminal is applied load, according to the conditions of the different causes of the loose, deformation and electrical characteristics may be reduced.
2, because when welding, water soluble flux to switch corrosion may, please avoid using.
3, on the condition of welding, please according to the actual conditions of mass production.
4, welding two times, please reply to the first part of the welding to the room temperature after the re. Continuous heating, there is the outer part of the deformation, the terminal of the loose, off and electrical characteristics may be reduced.
Power Supply
1, please don't let the flux from around the printed circuit board, switch to the top.
Press
1, after the installation of the switch, in order to make the other parts of the binder hardening, etc., through the heat storage hardening furnace, please contact us.
2, the use of the printed circuit board and the recommended circuit board, due to the influence of thermal stress will be changed, so please make full confirmation of the welding conditions in advance.
Slide
1, with a latch type, please plug in the welding position. If the bolt is welded the fixed point state, bolt mechanism Department has the possibility of deformation.
2, can not clean.
Rotation
1, especially the small, thin switch in the assembly parts of the installation process, please pay attention not to apply force.
2, tighten the mounting screws should be carried out within the specified time strength. If you use a greater force than the provisions of the screw, will cause the action of bad or screw damage.
Encoder
1, please insert the product ontology to the provisions of the installation, and so that the installation to reach the level of the state, if not to the level of the state, will lead to bad action.
2, if the voltage of DC1V or below 10 A below the use, there will be contact
