Good quality Carbon Composition Potentiometer for sales
Time is flying away, remember the first time we met in Ningbo in the year of 2005. I'm so happy with you and your team. Thanks for your support and let's look forward to the next years together.

—— Mr. Halit vergili

From partner to friend, you always give me surprise for your goods and service. We appreciate it so much. By the way, the pickled fish sauce is so nice. I'm self-confident of my cooking skills again. Don't forgot hot pot date next time.

RV28 28mm plastic shaft carbon potentiometer for welding machine

 

Description:

 

Carbon Potentiometer is an electronic component classified as variable resistor. Carbon Potentiometer is used as voltage divider to provide variable output voltage. Carbon Potentiometers uses carbon as resistive element. There are also different types of Potentiometers like Wire Wound type and ceramic type using different materials on resistive element. Carbon Potentiometer can be classified into logarithmic type and linear type depending on the mode of operations. Carbon Potentiometers are of many types and sizes depending on resistance value, power rating and type of mounting.

 

 

Mechanical specifications:

 

Total rotation angel The angle is measured by rotating shaft from the end of terminal R1 to the end of terminal R3. 260°±10°
Rotation torque Rotational torque when turn the shaft :without special provision,rotational speed is 60°/s in ambient temperature 5-35℃ 2-20mN.m
Stop torque The force that shaft transfer from terminal 1 to stop point or terminal 3 to stop point after 10 seconds until be break ≥5kgf.cm

 

Electrical specifications:

Total resistance Measurement shall be made by the resistance between terminal R1and R3. 500Ω ~2MΩ
Resistance taper Resistance changes B
Total Resistance tolerance Measurement shall be made by the resistance tolerance between terminal R1 and R3. ± 20%
Rated power Rated power is based on continuous full load operation at the maximum voltage between terminal R1 and R3. 0.5W(50 ℃)
Residual resistance Test residual resistance beteen terminal R1 and R2; terminal R2 and R3 R≤10KΩ R0≤20Ω 10KΩ<R≤100KΩ R0≤30Ω 100KΩ<R≤250KΩ
R0≤50Ω R≥250KΩ R0≤0.1%
Rotation of noise The murmur will appear when shaft turn from terminal 1 to terminal 3 by 30 rounds/minute equably speed. ≤47mV
Voltage proof Input more then one minute voltage between terminals and shell. 2000VAC
Max. operation voltage Maximal voltage which sustained by terminal R1 and R3 250VAC
Operating temperature Potentiometer of the performance guarantee for the use ambient temperature -30℃~70℃
Insulation resistance Test voltage:DC 500V,
Test position: Between terminal and case
200MΩ

 

Others:

Rotation life After 10,000 rotation after the test, the changes impacted no more than ± (15% R +0.5 Ω) rotational noise of not more than 100 mv
Terminal strength After welding (350℃, 3,5 seconds) after the of terminal contacts should be good, no termination loosening of
Soldering ability Dip the terminals into tin tank at 235°C±5°C for 5±0.5 seconds, the soldering area should be more than 90%.
