Rotary Potentiometer, Used in Electric Tools, Passed RoHS

Electrical  Property:

 

1

Total Resistance

Measurement shall be made by the resistance between terminals R1and R3

100Ω ~2MΩ

2

Resistance taper

Resistance changes

A: Log B: Linear

C: Alog

3

Total Resistance

tolerance

Measurement shall be made by the resistance tolerance between terminal R1 and R3.

100Ω~1M±20%,1MΩ~2MΩ±30%

4

Rated power

Rated power is based on continuous full load operation at the maximum voltage between terminal R1 and R3.

0.15W(50ºC)

5

Residual

resistance

Test residual resistance between terminal R1 andR2;terminal R2 andR3

R10KΩ  R0≤20Ω

10KΩ<R≤100KΩ

R0≤30Ω

100KΩ<R≤250KΩ

R0≤50Ω

R≥250KΩ  R0≤0.1%

6

rotation of noise

The murmur will appear when shaft turn from terminal 1 to terminal 3 by 30 rounds/minute equably speed.

≤47mV

7

Electrical Rotation

angle

Resistance effective changes in perspective

220°±20°

8

Max operating

voltage

Maximal voltage which sustained by terminal R1 and R3

200V DC

9

Switch current 

Switch silver contacts to inherit the maximum current

6A

Mechanical Property

 

1

Total rotation angle

The angle is measured by rotating shaft from the end of terminal R1 to the end of terminal R3

265°±10°

2

Rotation torque

Rotational torque when turn the shaft :without special provision, rotational speed is 60°/s in

ambient temperature 5-35°C

0.15-3.0Ncm

3

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

>5Ncm

The others

1

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

 

2

Terminal strength

After welding (350 ºC, 3,5 seconds) after the termination of terminal contacts should be good, no loosening of

 

3

Soldering ability

Dip the terminals into tin tank at 260ºC±5ºCfor 2±0.5 seconds, the soldering area should be more than 90%.
