Insulated shaft rotary potentiometer carbon film potentiometer
PC1601-H-B-P18
Description:
A potentiometer is an electrical component that provides variable
resistance. They're commonly found in user control circuits;
volume, speed, brightness, etc…
A wide variety of potmeters exist. Manually adjustable potmeters
can be divided in rotary or linear movement types. The tables below
list the available types and their applications of rotary
potentiometer
There are a number of terms in the electronics industry used to
describe certain types of potentiometers:
• Slide pot or slider pot: a potentiometer that is adjusted by sliding
the wiper left or right (or up and down, depending on the
installation), usually with a finger or thumb
• Thumb pot or thumbwheel pot: a small rotating potentiometer meant to
be adjusted infrequently by means of a small thumbwheel
• Trimpot or trimmer pot: a trimmer potentiometer typically meant to
be adjusted once or infrequently for "fine-tuning" an electrical
signal
Mechanical specifications:
| Total rotation angel | The angle is measured by rotating shaft from the end of terminal R1
to the end of terminal R3. | 300°±5° |
| Rotation torque | Rotational torque when turn the shaft :without special
provision,rotational speed is 60°/s in ambient temperature 5-35℃ | 0.3-1.5Ncm |
| 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 | >40Ncm |
Electrical specifications:
| Total resistance | Measurement shall be made by the resistance between terminal R1and
R3. | 1KΩ |
| 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. | 0.2W(50 ℃) |
| Residual resistance | Test residual resistance beteen terminal R1 and R2; terminal R2 and
R3 | R0≤50Ω |
| Rotation of noise | The murmur will appear when shaft turn from terminal 1 to terminal
3 by 30 rounds/minute equably speed. | ≤100mV |
| Electrical rotation angle | Resistance effective changes in perspective | 280°±20° |
| Max operating voltage | Maximal voltage which sustained by terminal R1 and R3 | 50VDC |
Others:
| Rotation life | After 25,000 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 260°C±5°C for 2±0.5 seconds, the
soldering area should be more than 90%. |
Application:
Potentiometers were used to control the picture brightness,
contrast, and colour response. A potentiometer was often used to
adjust “vertical hold”, which affected the synchronization between
the received picture signal and the receiver’s internal sweep
circuit (a multi-vibrator).
