Competitive Advantages:
1. High reliability
2. Sensitive and accurate
2. Weight < 2g
3. Long life cycles of 100,000 times
4. UL,CQC,VDE and RoHS certification approval
5. Wide application
Note:
1 , using the contact temperature installation should be charged with the metal cover up snapping apparatus mounting surface , to ensure that the temperature effect , should be coated with thermal grease or other similar thermal properties of the medium in the surface temperature .
2 , the installation can not cover up the top collapsed , loose or deformed , so as not to affect performance.
3, can not allow the liquid to penetrate the internal temperature may not make the shell cracks , are not free to change the shape of the external terminals.
4 , the product is not greater than 5A current in the circuit , chose the copper cross-section 0 5-1 mm 2 wire connection ; . No greater than 10A current in the circuit , chose the cross-section of 0.75-1.5 mm 2 copper wire connection.
5, the product should be less than 90% relative humidity , ambient temperature is below 40 °C ventilated, clean, dry , non-corrosive gases stored in the warehouse .
KSD-01F classification , in accordance with the temperature to points, can also be classified according to the material , you can also follow the installation way points.
According to the nature of the action : the action can be divided into normally open(H Type) and normally closed(D type).
