SCR30 rotary carbon film single turn potentiometer with metal shaft
Description:
The carbon film potentiometers are formed by depositing carbon composition ink on an insulating body, which in most of the cases is phenolic resin. This is one of the most commonly used materials for the pots that is quite cheap and has resolution better than the wire wound potentiometers. They have reasonable life and tolerable noise levels.
Mechanical specifications:
| Total rotation angel | The angle is measured by rotating shaft from the end of terminal R1 to the end of terminal R3. | 312°±10° |
| Rotation torque | Rotational torque when turn the shaft :without special provision,rotational speed is 60°/s in ambient temperature 5-35℃ | 150~450gf.cm |
| 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 | ≥12kgf.cm |
Electrical specifications:
| Total resistance | Measurement shall be made by the resistance between terminal R1and R3. | 100Ω ~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. | 2W(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. | 1000VAC |
| Max. operation voltage | Maximal voltage which sustained by terminal R1 and R3 | 500VAC |
| 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%. |
Resistance taper:
A letter code may be used to identify which taper is used, but the letter code definitions are not standardized. Potentiometers made in Asia and the USA are usually marked with an "A" for logarithmic taper or a "B" for linear taper; "C" for the rarely seen reverse logarithmic taper. Others, particularly those from Europe, may be marked with an "A" for linear taper, a "C" or "B" for logarithmic taper, or an "F" for reverse logarithmic taper.[2] The code used also varies between different manufacturers.
